- * Prototype: u64 cnt32_to_63(u32 cnt)
- * Many hardware clock counters are only 32 bits wide and therefore have
- * a relatively short period making wrap-arounds rather frequent.  This
- * is a problem when implementing sched_clock() for example, where a 64-bit
- * non-wrapping monotonic value is expected to be returned.
- *
- * To overcome that limitation, let's extend a 32-bit counter to 63 bits
- * in a completely lock free fashion. Bits 0 to 31 of the clock are provided
- * by the hardware while bits 32 to 62 are stored in memory.  The top bit in
- * memory is used to synchronize with the hardware clock half-period.  When
- * the top bit of both counters (hardware and in memory) differ then the
- * memory is updated with a new value, incrementing it when the hardware
- * counter wraps around.
- *
- * Because a word store in memory is atomic then the incremented value will
- * always be in synch with the top bit indicating to any potential concurrent
- * reader if the value in memory is up to date or not with regards to the
- * needed increment.  And any race in updating the value in memory is harmless
- * as the same value would simply be stored more than once.
- *
- * The only restriction for the algorithm to work properly is that this
- * code must be executed at least once per each half period of the 32-bit
- * counter to properly update the state bit in memory. This is usually not a
- * problem in practice, but if it is then a kernel timer could be scheduled
- * to manage for this code to be executed often enough.
- *
- * Note that the top bit (bit 63) in the returned value should be considered
- * as garbage.  It is not cleared here because callers are likely to use a
- * multiplier on the returned value which can get rid of the top bit
- * implicitly by making the multiplier even, therefore saving on a runtime
- * clear-bit instruction. Otherwise caller must remember to clear the top
- * bit explicitly.

+ *
+ * No data-dependent reads from memory-like regions are ever reordered
+ * over this barrier.  All reads preceding this primitive are guaranteed
+ * to access memory (but not necessarily other CPUs' caches) before any
+ * reads following this primitive that depend on the data return by
+ * any of the preceding reads.  This primitive is much lighter weight than
+ * rmb() on most CPUs, and is never heavier weight than is
+ * rmb().
+ *
+ * These ordering constraints are respected by both the local CPU
+ * and the compiler.
+ *
+ * Ordering is not guaranteed by anything other than these primitives,
+ * not even by data dependencies.  See the documentation for
+ * memory_barrier() for examples and URLs to more information.
+ *
+ * For example, the following code would force ordering (the initial
+ * value of "a" is zero, "b" is one, and "p" is "&a"):
+ *
+ * <programlisting>
+ *	CPU 0				CPU 1
+ *
+ *	b = 2;

+ *	p = &b;				q = p;
+ *					read_barrier_depends();

+ * NOTES about DMA transfers:

+ *  controller 1: channels 0-3, byte operations, ports 00-1F
+ *  controller 2: channels 4-7, word operations, ports C0-DF
+ *
+ *  - ALL registers are 8 bits only, regardless of transfer size
+ *  - channel 4 is not used - cascades 1 into 2.
+ *  - channels 0-3 are byte - addresses/counts are for physical bytes
+ *  - channels 5-7 are word - addresses/counts are for physical words
+ *  - transfers must not cross physical 64K (0-3) or 128K (5-7) boundaries
+ *  - transfer count loaded to registers is 1 less than actual count
+ *  - controller 2 offsets are all even (2x offsets for controller 1)
+ *  - page registers for 5-7 don't use data bit 0, represent 128K pages
+ *  - page registers for 0-3 use bit 0, represent 64K pages
+ *
+ * DMA transfers are limited to the lower 16MB of _physical_ memory.
+ * Note that addresses loaded into registers must be _physical_ addresses,
+ * not logical addresses (which may differ if paging is active).
+ *
+ *  Address mapping for channels 0-3:
+ *
+ *   A23 ... A16 A15 ... A8  A7 ... A0    (Physical addresses)
+ *    |  ...  |   |  ... |   |  ... |
+ *    |  ...  |   |  ... |   |  ... |
+ *    |  ...  |   |  ... |   |  ... |
+ *   P7  ...  P0  A7 ... A0  A7 ... A0
+ * |    Page    | Addr MSB | Addr LSB |   (DMA registers)
+ *
+ *  Address mapping for channels 5-7:
+ *
+ *   A23 ... A17 A16 A15 ... A9 A8 A7 ... A1 A0    (Physical addresses)
+ *    |  ...  |   \   \   ... \  \  \  ... \  \
+ *    |  ...  |    \   \   ... \  \  \  ... \  (not used)
+ *    |  ...  |     \   \   ... \  \  \  ... \
+ *   P7  ...  P1 (0) A7 A6  ... A0 A7 A6 ... A0
+ * |      Page      |  Addr MSB   |  Addr LSB  |   (DMA registers)
+ *
+ * Again, channels 5-7 transfer _physical_ words (16 bits), so addresses
+ * and counts _must_ be word-aligned (the lowest address bit is _ignored_ at
+ * the hardware level, so odd-byte transfers aren't possible).
+ *
+ * Transfer count (_not # bytes_) is limited to 64K, represented as actual
+ * count - 1 : 64K => 0xFFFF, 1 => 0x0000.  Thus, count is always 1 or more,
+ * and up to 128K bytes may be transferred on channels 5-7 in one operation.

+ * SMP/VPE-safe functions to access "registers" (see note).
+ *
+ * NOTES:
+* - These macros use ll/sc instructions, so it is your responsibility to
+ * ensure these are available on your platform before including this file.
+ * - The MIPS32 spec states that ll/sc results are undefined for uncached
+ * accesses. This means they can't be used on HW registers accessed
+ * through kseg1. Code which requires these macros for this purpose must
+ * front-end the registers with cached memory "registers" and have a single
+ * thread update the actual HW registers.
+ * - A maximum of 2k of code can be inserted between ll and sc. Every
+ * memory accesses between the instructions will increase the chance of
+ * sc failing and having to loop.
+ * - When using custom_read_reg32/custom_write_reg32 only perform the
+ * necessary logical operations on the register value in between these
+ * two calls. All other logic should be performed before the first call.
+  * - There is a bug on the R10000 chips which has a workaround. If you
+ * are affected by this bug, make sure to define the symbol 'R10000_LLSC_WAR'
+ * to be non-zero.  If you are using this header from within linux, you may
+ * include <asm/war.h> before including this file to have this defined
+ * appropriately for you.

+ * Notes:
+ *  1) The SPI registers are split into two blocks, one offset from the
+ *     MSP_SPI_BASE by 0x00 and the other offset from the MSP_SPI_BASE by
+ *     0x68.  The SPI driver definitions for the register must be aware
+ *     of this.
+ *  2) The block copy engine register are divided into two regions, one
+ *     for the control/configuration of the engine proper and one for the
+ *     values of the descriptors used in the copy process.  These have
+ *     different base defines (CTRL_BASE vs DESC_BASE)
+ *  3) These constants are for physical addresses which means that they
+ *     work correctly with "ioremap" and friends.  This means that device
+ *     drivers will need to remap these addresses using ioremap and perhaps
+ *     the readw/writew macros.  Or they could use the regptr() macro
+ *     defined below, but the readw/writew calls are the correct thing.
+ *  4) The UARTs have an additional status register offset from the base
+ *     address.  This register isn't used in the standard 8250 driver but
+ *     may be used in other software.  Consult the hardware datasheet for
+ *     offset details.
+ *  5) For some unknown reason the security engine (MSP_SEC_BASE) registers
+ *     start at an offset of 0x84 from the base address but the block of
+ *     registers before this is reserved for the security engine.  The
+ *     driver will have to be aware of this but it makes the register
+ *     definitions line up better with the documentation.

+    *  Some general notes:
+    *
+    *  Register addresses are grouped by function and follow the order
+    *  of the User Manual.
+    *
+    *  For the most part, when there is more than one peripheral
+    *  of the same type on the SOC, the constants below will be
+    *  offsets from the base of each peripheral.  For example,
+    *  the MAC registers are described as offsets from the first
+    *  MAC register, and there will be a MAC_REGISTER() macro
+    *  to calculate the base address of a given MAC.
+    *
+    *  The information in this file is based on the BCM1X55/BCM1X80
+    *  User Manual, Document 1X55_1X80-UM100-R, 22/12/03.
+    *
+    *  This file is basically a "what's new" header file.  Since the
+    *  BCM1250 and the new BCM1480 (and derivatives) share many common
+    *  features, this file contains only what's new or changed from
+    *  the 1250.  (above, you can see that we include the 1250 symbols
+    *  to get the base functionality).
+    *
+    *  In software, be sure to use the correct symbols, particularly
+    *  for blocks that are different between the two chip families.
+    *  All BCM1480-specific symbols have _BCM1480_ in their names,
+    *  and all BCM1250-specific and "base" functions that are common in
+    *  both chips have no special names (this is for compatibility with
+    *  older include files).  Therefore, if you're working with the
+    *  SCD, which is very different on each chip, A_SCD_xxx implies
+    *  the BCM1250 version and A_BCM1480_SCD_xxx implies the BCM1480
+    *  version.

+    *  Some general notes:
+    *
+    *  This file is basically a "what's new" header file.  Since the
+    *  BCM1250 and the new BCM1480 (and derivatives) share many common
+    *  features, this file contains only what's new or changed from
+    *  the 1250.  (above, you can see that we include the 1250 symbols
+    *  to get the base functionality).
+    *
+    *  In software, be sure to use the correct symbols, particularly
+    *  for blocks that are different between the two chip families.
+    *  All BCM1480-specific symbols have _BCM1480_ in their names,
+    *  and all BCM1250-specific and "base" functions that are common in
+    *  both chips have no special names (this is for compatibility with
+    *  older include files).  Therefore, if you're working with the
+    *  SCD, which is very different on each chip, A_SCD_xxx implies
+    *  the BCM1250 version and A_BCM1480_SCD_xxx implies the BCM1480
+    *  version.

+    *    #define SIBYTE_HDR_FEATURES	SIBYTE_HDR_FMASK_112x_PASS1
+    *
+    *		Generate defines only for that revision of chip.

+    *    #if SIBYTE_HDR_FEATURE(chip,pass)

+    *		True if header features for that revision or later of

+    *	        (Use this to bracket #defines for features present in a given
+    *		revision and later.)
+    *
+    *		Note that there is no implied ordering between chip types.
+    *
+    *		Note also that 'chip' and 'pass' must textually exactly
+    *		match the defines below.  So, for example,
+    *		SIBYTE_HDR_FEATURE(112x, PASS1) is OK, but
+    *		SIBYTE_HDR_FEATURE(1120, pass1) is not (for two reasons).
+    *
+    *    #if SIBYTE_HDR_FEATURE_UP_TO(chip,pass)
+    *

+    *		and earlier revisions of the named chip type.
+    *
+    *    #if SIBYTE_HDR_FEATURE_EXACT(chip,pass)
+    *
+    *		Same as SIBYTE_HDR_FEATURE, but only true for the named
+    *		revision of the named chip type.  (Note that this CANNOT
+    *		be used to verify that you're compiling only for that
+    *		particular chip/revision.  It will be true any time this
+    *		chip/revision is included in SIBYTE_HDR_FEATURES.)
+    *
+    *    #if SIBYTE_HDR_FEATURE_CHIP(chip)
+    *
+    *		True if header features for (any revision of) that chip type
+    *		are enabled in SIBYTE_HDR_FEATURES.  (Use this to bracket
+    *		#defines for features specific to a given chip type.)
+    *
+    *  Mask values currently include room for additional revisions of each
+    *  chip type, but can be renumbered at will.  Note that they MUST fit
+    *  into 31 bits and may not include C type constructs, for safe use in
+    *  CPP conditionals.  Bit positions within chip types DO indicate
+    *  ordering, so be careful when adding support for new minor revs.

+    *                  shifted to the correct position in the register.
+    *
+    *  S_xxx           SHIFT constant.  This is the number of bits that

+    *  For the most part, when there is more than one peripheral

+ * The KLCONFIG area is organized as a LINKED LIST of BOARDs. A BOARD
+ * can be either 'LOCAL' or 'REMOTE'. LOCAL means it is attached to
+ * the LOCAL/current NODE. REMOTE means it is attached to a different
+ * node.(TBD - Need a way to treat ROUTER boards.)
+ *
+ * There are 2 different structures to represent these boards -
+ * lboard - Local board, rboard - remote board. These 2 structures
+ * can be arbitrarily mixed in the LINKED LIST of BOARDs. (Refer
+ * Figure below). The first byte of the rboard or lboard structure
+ * is used to find out its type - no unions are used.
+ * If it is a lboard, then the config info of this board will be found
+ * on the local node. (LOCAL NODE BASE + offset value gives pointer to
+ * the structure.
+ * If it is a rboard, the local structure contains the node number
+ * and the offset of the beginning of the LINKED LIST on the remote node.
+ * The details of the hardware on a remote node can be built locally,
+ * if required, by reading the LINKED LIST on the remote node and
+ * ignoring all the rboards on that node.
+ *
+ * The local node uses the REMOTE NODE NUMBER + OFFSET to point to the
+ * First board info on the remote node. The remote node list is
+ * traversed as the local list, using the REMOTE BASE ADDRESS and not
+ * the local base address and ignoring all rboard values.

+ * Each BOARD consists of COMPONENTs and the BOARD structure has
+ * pointers (offsets) to its COMPONENT structure.
+ * The COMPONENT structure has version info, size and speed info, revision,
+ * error info and the NIC info. This structure can accommodate any
+ * BOARD with arbitrary COMPONENT composition.
+ *
+ * The ERRORINFO part of each BOARD has error information
+ * that describes errors about the BOARD itself. It also has flags to
+ * indicate the COMPONENT(s) on the board that have errors. The error
+ * information specific to the COMPONENT is present in the respective
+ * COMPONENT structure.
+ *
+ * The ERRORINFO structure is also treated like a COMPONENT, ie. the
+ * BOARD has pointers(offset) to the ERRORINFO structure. The rboard
+ * structure also has a pointer to the ERRORINFO structure. This is
+ * the place to store ERRORINFO about a REMOTE NODE, if the HUB on
+ * that NODE is not working or if the REMOTE MEMORY is BAD. In cases where
+ * only the CPU of the REMOTE NODE is disabled, the ERRORINFO pointer can
+ * be a NODE NUMBER, REMOTE OFFSET combination, pointing to error info
+ * which is present on the REMOTE NODE.(TBD)
+ * REMOTE ERRINFO can be stored on any of the nearest nodes
+ * or on all the nearest nodes.(TBD)
+ * Like BOARD structures, REMOTE ERRINFO structures can be built locally
+ * using the rboard errinfo pointer.
+ *
+ * In order to get useful information from this Data organization, a set of
+ * interface routines are provided (TBD). The important thing to remember while
+ * manipulating the structures, is that, the NODE number information should
+ * be used. If the NODE is non-zero (remote) then each offset should
+ * be added to the REMOTE BASE ADDR else it should be added to the LOCAL BASE ADDR.
+ * This includes offsets for BOARDS, COMPONENTS and ERRORINFO.
+ *
+ * Note that these structures do not provide much info about connectivity.
+ * That info will be part of HWGRAPH, which is an extension of the cfg_t
+ * data structure. (ref IP27prom/cfg.h) It has to be extended to include
+ * the IO part of the Network(TBD).
+ *
+ * The data structures below define the above concepts.

+ *	copy of the task_struct, which is currently not used by gdb,

+ *	are stored as part of the upage.  The upage should always be
+ *	only one page long.
+ *  data: The data segment follows next.  We use current->end_text to
+ *	current->brk to pick up all of the user variables, plus any memory
+ *	that may have been sbrk'ed.  No attempt is made to determine if a
+ *	page is demand-zero or if a page is totally unused, we just cover
+ *	the entire range.  All of the addresses are rounded in such a way
+ *	that an integral number of pages is written.
+ *  stack: We need the stack information in order to get a meaningful
+ *	backtrace.  We need to write the data from usp to
+ *	current->start_stack, so we round each of these in order to be able

+ * Variant clock event timer support for SMTC on MIPS 34K, 1004K
+ * or other MIPS MT cores.
+ *
+ * Notes on SMTC Support:
+ *
+ * SMTC has multiple microthread TCs pretending to be Linux CPUs.
+ * But there's only one Count/Compare pair per VPE, and Compare
+ * interrupts are taken opportunisitically by available TCs
+ * bound to the VPE with the Count register.  The new timer
+ * framework provides for global broadcasts, but we really
+ * want VPE-level multicasts for best behavior. So instead
+ * of invoking the high-level clock-event broadcast code,
+ * this version of SMTC support uses the historical SMTC
+ * multicast mechanisms "under the hood", appearing to the
+ * generic clock layer as if the interrupts are per-CPU.
+ *
+ * The approach taken here is to maintain a set of NR_CPUS
+ * virtual timers, and track which "CPU" needs to be alerted
+ * at each event.
+ *
+ * It's unlikely that we'll see a MIPS MT core with more than
+ * 2 VPEs, but we *know* that we won't need to handle more
+ * VPEs than we have "CPUs".  So NCPUs arrays of NCPUs elements
+ * is always going to be overkill, but always going to be enough.

  *
- * P3: Translation from irq 0x0d to mask 0x2000 is for MrCoffee.
+ * This ambiguity is resolved in the 'intr' property for device nodes
+ * in the OF device tree.  Each 'intr' property entry is composed of
+ * two 32-bit words.  The first word is the IRQ priority value, which
+ * is what we're intersted in.  The second word is the IRQ vector, which
+ * is unused.
+ *
+ * The low 4 bits of the IRQ priority indicate the PIL, and the upper
+ * 4 bits indicate onboard vs. SBUS leveled vs. VME leveled.  0x20
+ * means onboard, 0x30 means SBUS leveled, and 0x40 means VME leveled.
+ *
+ * For example, an 'intr' IRQ priority value of 0x24 is onboard SCSI
+ * whereas a value of 0x33 is SBUS level 2.  Here are some sample
+ * 'intr' property IRQ priority values from ss4, ss5, ss10, ss20, and
+ * Tadpole S3 GX systems.

  *
- * The implementation, however, is not as general as it might seem. In

- *	Pentium III, Xeon, Pentium 4, etc.
- *

- *	1.0	16 Feb 2000, Tigran Aivazian <tigran@sco.com>
- *		Initial release.
- *	1.01	18 Feb 2000, Tigran Aivazian <tigran@sco.com>
- *		Added read() support + cleanups.
- *	1.02	21 Feb 2000, Tigran Aivazian <tigran@sco.com>
- *		Added 'device trimming' support. open(O_WRONLY) zeroes
- *		and frees the saved copy of applied microcode.
- *	1.03	29 Feb 2000, Tigran Aivazian <tigran@sco.com>
- *		Made to use devfs (/dev/cpu/microcode) + cleanups.
- *	1.04	06 Jun 2000, Simon Trimmer <simon@veritas.com>
- *		Added misc device support (now uses both devfs and misc).
- *		Added MICROCODE_IOCFREE ioctl to clear memory.
- *	1.05	09 Jun 2000, Simon Trimmer <simon@veritas.com>
- *		Messages for error cases (non Intel & no suitable microcode).
- *	1.06	03 Aug 2000, Tigran Aivazian <tigran@veritas.com>
- *		Removed ->release(). Removed exclusive open and status bitmap.
- *		Added microcode_rwsem to serialize read()/write()/ioctl().
- *		Removed global kernel lock usage.
- *	1.07	07 Sep 2000, Tigran Aivazian <tigran@veritas.com>
- *		Write 0 to 0x8B msr and then cpuid before reading revision,
- *		so that it works even if there were no update done by the
- *		BIOS. Otherwise, reading from 0x8B gives junk (which happened
- *		to be 0 on my machine which is why it worked even when I
- *		disabled update by the BIOS)
- *		Thanks to Eric W. Biederman <ebiederman@lnxi.com> for the fix.
- *	1.08	11 Dec 2000, Richard Schaal <richard.schaal@intel.com> and
- *			     Tigran Aivazian <tigran@veritas.com>
- *		Intel Pentium 4 processor support and bugfixes.
- *	1.09	30 Oct 2001, Tigran Aivazian <tigran@veritas.com>
- *		Bugfix for HT (Hyper-Threading) enabled processors
- *		whereby processor resources are shared by all logical processors
- *		in a single CPU package.
- *	1.10	28 Feb 2002 Asit K Mallick <asit.k.mallick@intel.com> and
- *		Tigran Aivazian <tigran@veritas.com>,
- *		Serialize updates as required on HT processors due to speculative
- *		nature of implementation.
- *	1.11	22 Mar 2002 Tigran Aivazian <tigran@veritas.com>
- *		Fix the panic when writing zero-length microcode chunk.
- *	1.12	29 Sep 2003 Nitin Kamble <nitin.a.kamble@intel.com>,
- *		Jun Nakajima <jun.nakajima@intel.com>
- *		Support for the microcode updates in the new format.
- *	1.13	10 Oct 2003 Tigran Aivazian <tigran@veritas.com>
- *		Removed ->read() method and obsoleted MICROCODE_IOCFREE ioctl
- *		because we no longer hold a copy of applied microcode
- *		in kernel memory.
- *	1.14	25 Jun 2004 Tigran Aivazian <tigran@veritas.com>
- *		Fix sigmatch() macro to handle old CPUs with pf == 0.
- *		Thanks to Stuart Swales for pointing out this bug.

+ *	Pentium III, Xeon, Pentium 4, etc.
+ *
+ *	Reference: Section 8.11 of Volume 3a, IA-32 Intel? Architecture

+ *
+ *	1.0	16 Feb 2000, Tigran Aivazian <tigran@sco.com>
+ *		Initial release.
+ *	1.01	18 Feb 2000, Tigran Aivazian <tigran@sco.com>
+ *		Added read() support + cleanups.
+ *	1.02	21 Feb 2000, Tigran Aivazian <tigran@sco.com>
+ *		Added 'device trimming' support. open(O_WRONLY) zeroes
+ *		and frees the saved copy of applied microcode.
+ *	1.03	29 Feb 2000, Tigran Aivazian <tigran@sco.com>
+ *		Made to use devfs (/dev/cpu/microcode) + cleanups.
+ *	1.04	06 Jun 2000, Simon Trimmer <simon@veritas.com>
+ *		Added misc device support (now uses both devfs and misc).
+ *		Added MICROCODE_IOCFREE ioctl to clear memory.
+ *	1.05	09 Jun 2000, Simon Trimmer <simon@veritas.com>
+ *		Messages for error cases (non Intel & no suitable microcode).
+ *	1.06	03 Aug 2000, Tigran Aivazian <tigran@veritas.com>
+ *		Removed ->release(). Removed exclusive open and status bitmap.
+ *		Added microcode_rwsem to serialize read()/write()/ioctl().
+ *		Removed global kernel lock usage.
+ *	1.07	07 Sep 2000, Tigran Aivazian <tigran@veritas.com>
+ *		Write 0 to 0x8B msr and then cpuid before reading revision,
+ *		so that it works even if there were no update done by the
+ *		BIOS. Otherwise, reading from 0x8B gives junk (which happened
+ *		to be 0 on my machine which is why it worked even when I
+ *		disabled update by the BIOS)
+ *		Thanks to Eric W. Biederman <ebiederman@lnxi.com> for the fix.
+ *	1.08	11 Dec 2000, Richard Schaal <richard.schaal@intel.com> and
+ *			     Tigran Aivazian <tigran@veritas.com>
+ *		Intel Pentium 4 processor support and bugfixes.
+ *	1.09	30 Oct 2001, Tigran Aivazian <tigran@veritas.com>
+ *		Bugfix for HT (Hyper-Threading) enabled processors
+ *		whereby processor resources are shared by all logical processors
+ *		in a single CPU package.
+ *	1.10	28 Feb 2002 Asit K Mallick <asit.k.mallick@intel.com> and
+ *		Tigran Aivazian <tigran@veritas.com>,
+ *		Serialize updates as required on HT processors due to
+ *		speculative nature of implementation.
+ *	1.11	22 Mar 2002 Tigran Aivazian <tigran@veritas.com>
+ *		Fix the panic when writing zero-length microcode chunk.
+ *	1.12	29 Sep 2003 Nitin Kamble <nitin.a.kamble@intel.com>,
+ *		Jun Nakajima <jun.nakajima@intel.com>
+ *		Support for the microcode updates in the new format.
+ *	1.13	10 Oct 2003 Tigran Aivazian <tigran@veritas.com>
+ *		Removed ->read() method and obsoleted MICROCODE_IOCFREE ioctl
+ *		because we no longer hold a copy of applied microcode
+ *		in kernel memory.
+ *	1.14	25 Jun 2004 Tigran Aivazian <tigran@veritas.com>
+ *		Fix sigmatch() macro to handle old CPUs with pf == 0.
+ *		Thanks to Stuart Swales for pointing out this bug.

+ *		      2006	Shaohua Li <shaohua.li@intel.com>
+ *
+ *	This driver allows to upgrade microcode on Intel processors
+ *	belonging to IA-32 family - PentiumPro, Pentium II,
+ *	Pentium III, Xeon, Pentium 4, etc.
+ *
+ *	Reference: Section 8.11 of Volume 3a, IA-32 Intel? Architecture
+ *	Software Developer's Manual
+ *	Order Number 253668 or free download from:
+ *

+ *
+ *	1.0	16 Feb 2000, Tigran Aivazian <tigran@sco.com>
+ *		Initial release.
+ *	1.01	18 Feb 2000, Tigran Aivazian <tigran@sco.com>
+ *		Added read() support + cleanups.
+ *	1.02	21 Feb 2000, Tigran Aivazian <tigran@sco.com>
+ *		Added 'device trimming' support. open(O_WRONLY) zeroes
+ *		and frees the saved copy of applied microcode.
+ *	1.03	29 Feb 2000, Tigran Aivazian <tigran@sco.com>
+ *		Made to use devfs (/dev/cpu/microcode) + cleanups.
+ *	1.04	06 Jun 2000, Simon Trimmer <simon@veritas.com>
+ *		Added misc device support (now uses both devfs and misc).
+ *		Added MICROCODE_IOCFREE ioctl to clear memory.
+ *	1.05	09 Jun 2000, Simon Trimmer <simon@veritas.com>
+ *		Messages for error cases (non Intel & no suitable microcode).
+ *	1.06	03 Aug 2000, Tigran Aivazian <tigran@veritas.com>
+ *		Removed ->release(). Removed exclusive open and status bitmap.
+ *		Added microcode_rwsem to serialize read()/write()/ioctl().
+ *		Removed global kernel lock usage.
+ *	1.07	07 Sep 2000, Tigran Aivazian <tigran@veritas.com>
+ *		Write 0 to 0x8B msr and then cpuid before reading revision,
+ *		so that it works even if there were no update done by the
+ *		BIOS. Otherwise, reading from 0x8B gives junk (which happened
+ *		to be 0 on my machine which is why it worked even when I
+ *		disabled update by the BIOS)
+ *		Thanks to Eric W. Biederman <ebiederman@lnxi.com> for the fix.
+ *	1.08	11 Dec 2000, Richard Schaal <richard.schaal@intel.com> and
+ *			     Tigran Aivazian <tigran@veritas.com>
+ *		Intel Pentium 4 processor support and bugfixes.
+ *	1.09	30 Oct 2001, Tigran Aivazian <tigran@veritas.com>
+ *		Bugfix for HT (Hyper-Threading) enabled processors
+ *		whereby processor resources are shared by all logical processors
+ *		in a single CPU package.
+ *	1.10	28 Feb 2002 Asit K Mallick <asit.k.mallick@intel.com> and
+ *		Tigran Aivazian <tigran@veritas.com>,
+ *		Serialize updates as required on HT processors due to
+ *		speculative nature of implementation.
+ *	1.11	22 Mar 2002 Tigran Aivazian <tigran@veritas.com>
+ *		Fix the panic when writing zero-length microcode chunk.
+ *	1.12	29 Sep 2003 Nitin Kamble <nitin.a.kamble@intel.com>,
+ *		Jun Nakajima <jun.nakajima@intel.com>
+ *		Support for the microcode updates in the new format.
+ *	1.13	10 Oct 2003 Tigran Aivazian <tigran@veritas.com>
+ *		Removed ->read() method and obsoleted MICROCODE_IOCFREE ioctl
+ *		because we no longer hold a copy of applied microcode
+ *		in kernel memory.
+ *	1.14	25 Jun 2004 Tigran Aivazian <tigran@veritas.com>
+ *		Fix sigmatch() macro to handle old CPUs with pf == 0.
+ *		Thanks to Stuart Swales for pointing out this bug.
