-	help
-	  Say y to enable the watchdog during the kernel decompression
-	  stage. If the kernel fails to uncompress, then the watchdog
-	  will trigger a reset and the system should restart.
-
-	  Although this uses the same hardware unit as the kernel watchdog
-	  driver, it is not a replacement for it. If you use this option,
-	  you will have to use the watchdg driver to either stop the timeout
-	  or restart it. If you do not, then your kernel will reboot after
-	  startup.
-
-	  The driver uses a fixed timeout value, so the exact time till the
-	  system resets depends on the value of PCLK. The timeout on an
-	  200MHz s3c2410 should be about 30 seconds.

+ * Spec
+ *
+ * memcpy copies len bytes from src to dst and sets v0 to dst.
+ * It assumes that
+ *   - src and dst don't overlap
+ *   - src is readable
+ *   - dst is writable
+ * memcpy uses the standard calling convention
+ *
+ * __copy_user copies up to len bytes from src to dst and sets a2 (len) to
+ * the number of uncopied bytes due to an exception caused by a read or write.
+ * __copy_user assumes that src and dst don't overlap, and that the call is
+ * implementing one of the following:
+ *   copy_to_user
+ *     - src is readable  (no exceptions when reading src)
+ *   copy_from_user
+ *     - dst is writable  (no exceptions when writing dst)
+ * __copy_user uses a non-standard calling convention; see
+ * include/asm-mips/uaccess.h
+ *
+ * When an exception happens on a load, the handler must
+ # ensure that all of the destination buffer is overwritten to prevent
+ * leaking information to user mode programs.
+ */
+
+/*
+ * Implementation
+ */
+
+/*
+ * The exception handler for loads requires that:
+ *  1- AT contain the address of the byte just past the end of the source
+ *     of the copy,
+ *  2- src_entry <= src < AT, and
+ *  3- (dst - src) == (dst_entry - src_entry),
+ * The _entry suffix denotes values when __copy_user was called.
+ *
+ * (1) is set up up by uaccess.h and maintained by not writing AT in copy_user
+ * (2) is met by incrementing src by the number of bytes copied
+ * (3) is met by not doing loads between a pair of increments of dst and src
+ *
+ * The exception handlers for stores adjust len (if necessary) and return.
+ * These handlers do not need to overwrite any data.
+ *
+ * For __rmemcpy and memmove an exception is always a kernel bug, therefore
+ * they're not protected.

-	  on-die temperature in /proc/cpuinfo if the cpu supports it.
-
-	  Unfortunately, on some chip revisions, this sensor is very inaccurate

-config TAU_INT

-	  The TAU supports an interrupt driven mode which causes an interrupt

-	  to get notified the temp has exceeded a range. With this option off,
-	  a timer is used to re-check the temperature periodically.
-
-	  However, on some cpus it appears that the TAU interrupt hardware
-	  is buggy and can cause a situation which would lead unexplained hard
-	  lockups.
-
-	  Unless you are extending the TAU driver, or enjoy kernel/hardware
-	  debugging, leave this option off.
-
-config TAU_AVERAGE
-	bool "Average high and low temp"
-	depends on TAU
-	---help---
-	  The TAU hardware can compare the temperature to an upper and lower
-	  bound.  The default behavior is to show both the upper and lower
-	  bound in /proc/cpuinfo. If the range is large, the temperature is
-	  either changing a lot, or the TAU hardware is broken (likely on some
-	  G4's). If the range is small (around 4 degrees), the temperature is
-	  relatively stable.  If you say Y here, a single temperature value,
-	  halfway between the upper and lower bounds, will be reported in
-	  /proc/cpuinfo.
-
-	  If in doubt, say N here.

+	  If you say N here, these extra instructions will not be included,

+	  temperature within 2-4 degrees Celsius. This option shows the current
+	  on-die temperature in /proc/cpuinfo if the cpu supports it.
+
+	  Unfortunately, on some chip revisions, this sensor is very inaccurate
+	  and in many cases, does not work at all, so don't assume the cpu
+	  temp is actually what /proc/cpuinfo says it is.
+
+config TAU_INT
+	bool "Interrupt driven TAU driver (DANGEROUS)"
+	depends on TAU
+	---help---
+	  The TAU supports an interrupt driven mode which causes an interrupt
+	  whenever the temperature goes out of range. This is the fastest way
+	  to get notified the temp has exceeded a range. With this option off,
+	  a timer is used to re-check the temperature periodically.
+
+	  However, on some cpus it appears that the TAU interrupt hardware
+	  is buggy and can cause a situation which would lead unexplained hard
+	  lockups.
+
+	  Unless you are extending the TAU driver, or enjoy kernel/hardware
+	  debugging, leave this option off.
+
+config TAU_AVERAGE
+	bool "Average high and low temp"
+	depends on TAU
+	---help---
+	  The TAU hardware can compare the temperature to an upper and lower
+	  bound.  The default behavior is to show both the upper and lower
+	  bound in /proc/cpuinfo. If the range is large, the temperature is
+	  either changing a lot, or the TAU hardware is broken (likely on some
+	  G4's). If the range is small (around 4 degrees), the temperature is
+	  relatively stable.  If you say Y here, a single temperature value,
+	  halfway between the upper and lower bounds, will be reported in
+	  /proc/cpuinfo.
+
+	  If in doubt, say N here.
+

+	  The QUICC Engine (QE) is a new generation of communications
+	  coprocessors on Freescale embedded CPUs (akin to CPM in older chips).

 /*
  * thermal support for the cell processor
  *
+ * This module adds some sysfs attributes to cpu and spu nodes.
+ * Base for measurements are the digital thermal sensors (DTS)
+ * located on the chip.
+ * The accuracy is 2 degrees, starting from 65 up to 125 degrees celsius
+ * The attributes can be found under
+ * /sys/devices/system/cpu/cpuX/thermal
+ * /sys/devices/system/spu/spuX/thermal
+ *
+ * The following attributes are added for each node:
+ * temperature:
+ *	contains the current temperature measured by the DTS
+ * throttle_begin:
+ *	throttling begins when temperature is greater or equal to
+ *	throttle_begin. Setting this value to 125 prevents throttling.
+ * throttle_end:
+ *	throttling is being ceased, if the temperature is lower than
+ *	throttle_end. Due to a delay between applying throttling and
+ *	a reduced temperature this value should be less than throttle_begin.
+ *	A value equal to throttle_begin provides only a very little hysteresis.
+ * throttle_full_stop:
+ *	If the temperatrue is greater or equal to throttle_full_stop,
+ *	full throttling is applied to the cpu or spu. This value should be
+ *	greater than throttle_begin and throttle_end. Setting this value to
+ *	65 prevents the unit from running code at all.

-/* This is a modified version of linux/drivers/sound/dmasound.c to
- * support the CS4218 codec on the 8xx TDM port.  Thanks to everyone
- * that contributed to the dmasound software (which includes me :-).
- *
- * The CS4218 is configured in Mode 4, sub-mode 0.  This provides
- * left/right data only on the TDM port, as a 32-bit word, per frame
- * pulse.  The control of the CS4218 is provided by some other means,
- * like the SPI port.
- * Dan Malek (dmalek@jlc.net)

-/* ++TeSche: radically changed for new expanding purposes...
- *
- * These two routines now deal with copying/expanding/translating the samples
- * from user space into our buffer at the right frequency. They take care about
- * how much data there's actually to read, how much buffer space there is and
- * to convert samples into the right frequency/encoding. They will only work on
- * complete samples so it may happen they leave some bytes in the input stream
- * if the user didn't write a multiple of the current sample size. They both
- * return the number of bytes they've used from both streams so you may detect
- * such a situation. Luckily all programs should be able to cope with that.
- *
- * I think I've optimized anything as far as one can do in plain C, all
- * variables should fit in registers and the loops are really short. There's
- * one loop for every possible situation. Writing a more generalized and thus
- * parameterized loop would only produce slower code. Feel free to optimize
- * this in assembler if you like. :)
- *
- * I think these routines belong here because they're not yet really hardware
- * independent, especially the fact that the Falcon can play 16bit samples
- * only in stereo is hardcoded in both of them!
- *
- * ++geert: split in even more functions (one per format)
