2007-08-20ide: fix hidden dependencies on CONFIG_IDE_GENERICBartlomiej Zolnierkiewicz
Some host drivers depend on CONFIG_IDE_GENERIC to do the probing but their config options lack explicit dependencies on IDE_GENERIC. In the long-term these host drivers should be fixed to do the probing themselves but for now fix them by making their config options select CONFIG_IDE_GENERIC.

2007-08-20ide: make CONFIG_IDE_GENERIC default to NTejun Heo
These days, CONFIG_IDE_GENERIC causes more confusion and misconfiguration than it helps. Especially so because libata is linked after the generic driver. Default to N.

2007-08-20V4L/DVB (6027): Get rid of an ill-behaved msleep in i2c writeJonathan Corbet
Configuring the OLPC camera requires something over 150 register writes. Unfortunately, querying the CAFE i2c controller too soon after a write causes the hardware to flake. The problem had been "solved" with an msleep() call, but, between the number of registers and how msleep() behaves, that resulted in a 3-second delay on camera initialization. Instead, we hand-code a wait for the completion interrupt which avoids reading the status registers.

2007-08-19KVM: Avoid calling smp_call_function_single() with interrupts disabledAvi Kivity
When taking a cpu down, we need to hardware_disable() it. Unfortunately, the CPU_DYING notifier is called with interrupts disabled, which means we can't use smp_call_function_single(). Fortunately, the CPU_DYING notifier is always called on the dying cpu, so we don't need to use the function at all and can simply call hardware_disable() directly.

2007-08-18x86: properly initialize temp insn buffer for paravirt patchingChris Wright
With commit ab144f5ec64c42218a555ec1dbde6b60cf2982d6 the patching code now collects the complete new instruction stream into a temp buffer before finally patching in the new insns. In some cases the paravirt patchers will choose to leave the patch site unpatched (length mismatch, clobbers mismatch, etc). This causes the new patching code to copy an uninitialized temp buffer, i.e. garbage, to the callsite. Simply make sure to always initialize the buffer with the original instruction stream. A better fix is to audit all the patchers and return proper length so that apply_paravirt() can skip copies when we leave the patch site untouched.

2007-08-18fix random hang in forcedeth driver when using netconsoleTimo Jantunen
If the forcedeth driver receives too much work in an interrupt, it assumes it has a broken hardware with stuck IRQ. It works around the problem by disabling interrupts on the nic but makes a printk while holding device spinlog - which isn't smart thing to do if you have netconsole on the same nic. This patch moves the printk's out of the spinlock protected area. Without this patch the machine hangs hard. With this patch everything still works even when there is significant increase on CPU usage while using the nic.

2007-08-18i386: Fix a couple busy loops in mach_wakecpu.h:wait_for_init_deassert()Satyam Sharma
Use cpu_relax() in the busy loops, as atomic_read() doesn't automatically imply volatility for i386 and x86_64. x86_64 doesn't have this issue because it open-codes the while loop in smpboot.c:smp_callin() itself that already uses cpu_relax(). For i386, however, smpboot.c:smp_callin() calls wait_for_init_deassert() which is buggy for mach-default and mach-es7000 cases. [ I test-built a kernel -- smp_callin() itself got inlined in its only callsite, smpboot.c:start_secondary() -- and the relevant piece of code disassembles to the following: 0xc1019704 <start_secondary+12>: mov 0xc144c4c8,%eax 0xc1019709 <start_secondary+17>: test %eax,%eax 0xc101970b <start_secondary+19>: je 0xc1019709 <start_secondary+17> init_deasserted (at 0xc144c4c8) gets fetched into %eax only once and then we loop over the test of the stale value in the register only, so these look like real bugs to me. With the fix below, this becomes: 0xc1019706 <start_secondary+14>: pause 0xc1019708 <start_secondary+16>: cmpl $0x0,0xc144c4c8 0xc101970f <start_secondary+23>: je 0xc1019706 <start_secondary+14> which looks nice and healthy. ] Thanks to Heiko Carstens for noticing this.

2007-08-17[POWERPC] Fix interrupt routing and setup of ULI M1575 on FSL boardsKumar Gala
The interrupt routing in the device trees for the ULI M1575 was inproperly using the interrupt line field as pci function. Fixed up the device tree's to actual conform for to specification and changed the interrupt mapping code so it just uses a static mapping setup as follows: PIRQA - IRQ9 PIRQB - IRQ10 PIRQC - IRQ11 PIRQD - IRQ12 USB 1.1 OCHI (1c.0) - IRQ12 USB 1.1 OCHI (1c.1) - IRQ9 USB 1.1 OCHI (1c.2) - IRQ10 USB 1.1 ECHI (1c.3) - IRQ11 LAN (1b.0) - IRQ6 AC97 (1d.0) - IRQ6 Modem (1d.1) - IRQ6 HD Audio (1d.2) - IRQ6 SATA (1f.1) - IRQ5 SMB (1e.1) - IRQ7 PMU (1e.2) - IRQ7 PATA (1f.0) - IRQ14/15 Took the oppurtunity to refactor the code into a single file so we don't have to duplicate these fixes on the two current boards in the tree and several forth coming boards that will also need the code. Fixed RTC support that requires a dummy memory read on the P2P bridge to unlock the RTC and setup the default of the RTC alarm registers to match with a basic x86 style CMOS RTC. Moved code that poked ISA registers to a FIXUP_FINAL quirk to ensure the PCI IO space has been setup properly before we start poking ISA registers at random locations.

2007-08-16[MATH-EMU]: Fix underflow exception reporting.David S. Miller
The underflow exception cases were wrong. This is one weird area of ieee1754 handling in that the underflow behavior changes based upon whether underflow is enabled in the trap enable mask of the FPU control register. As a specific case the Sparc V9 manual gives us the following description: -------------------- If UFM = 0: Underflow occurs if a nonzero result is tiny and a loss of accuracy occurs. Tininess may be detected before or after rounding. Loss of accuracy may be either a denormalization loss or an inexact result. If UFM = 1: Underflow occurs if a nonzero result is tiny. Tininess may be detected before or after rounding. -------------------- What this amounts to in the packing case is if we go subnormal, we set underflow if any of the following are true: 1) rounding sets inexact 2) we ended up rounding back up to normal (this is the case where we set the exponent to 1 and set the fraction to zero), this should set inexact too 3) underflow is set in FPU control register trap-enable mask The initially discovered example was "DBL_MIN / 16.0" which incorrectly generated an underflow. It should not, unless underflow is set in the trap-enable mask of the FPU csr. Another example, "0x0.0000000000001p-1022 / 16.0", should signal both inexact and underflow. The cpu implementations and ieee1754 literature is very clear about this. This is case #2 above. However, if underflow is set in the trap enable mask, only underflow should be set and reported as a trap. That is handled properly by the prioritization logic in arch/sparc{,64}/math-emu/math.c:record_exception(). Based upon a report and test case from Jakub Jelinek. Signed-off-by: David S. Miller <davem@davemloft.net>
