v2.4.9.1 -> v2.4.9.2

  - Al Viro: block device cleanups
  - Marcelo Tosatti: make bounce buffer allocations more robust (it's ok
  for them to do IO, just not cause recursive bounce IO. So allow them)
  - Anton Altaparmakov: NTFS update (1.1.17)
  - Paul Mackerras: PPC update (big re-org)
  - Petko Manolov: USB pegasus driver fixes
  - David Miller: networking and sparc updates
  - Trond Myklebust: Export atomic_dec_and_lock
  - OGAWA Hirofumi: find and fix umsdos "filldir" users that were broken
  by the 64-bit-cleanups. Fix msdos warnings.
  - Al Viro: superblock handling cleanups and race fixes
  - Johannes Erdfelt++: USB updates

 CONFIG_ALL_PPC
   Linux currently supports several different kinds of PowerPC-based
   machines: Apple Power Macintoshes and clones (such as the Motorola

+  as the Motorola PowerStacks, Motorola cPCI/VME embedded systems,
+  and some IBM RS/6000 systems), CHRP (Common Hardware Reference
+  Platform), and several embedded PowerPC systems containing 4xx, 6xx,
+  7xx, 8xx, 74xx, and 82xx processors.  Currently, the default option
+  is to build a kernel which works on the first three. 
+
+AltiVec Kernel Support
+CONFIG_ALTIVEC
+  This option enables kernel support for the Altivec extensions to the
+  PowerPC processor. The kernel currently supports saving and restoring
+  altivec registers, and turning on the 'altivec enable' bit so user
+  processes can execute altivec instructions.
+
+  This option is only usefully if you have a processor that supports 
+  altivec (G4, otherwise known as 74xx series), but does not have
+  any affect on a non-altivec cpu (it does, however add code to the
+  kernel).
+
+  If in doubt, say Y here.
+
+Thermal Management Support
+CONFIG_TAU
+  G3 and G4 processors have an on-chip temperature sensor called the
+  'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
+  temperature within 2-4 degrees celcius. 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 some cases, does not work at all, so don't assume the cpu
+  temp is actually what /proc/cpuinfo says it is.
+
+Interrupt driven TAU driver
+CONFIG_TAU_INT
+  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.
+
+Average high and low temp
+CONFIG_TAU_AVERAGE
+  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.
+
+Support for CUDA based PowerMacs
+CONFIG_ADB_CUDA
+  This provides support for CUDA based Power Macintosh systems.  This
+  includes most OldWorld PowerMacs, the first generation iMacs, the
+  Blue&White G3 and the Yikes G4 (PCI Graphics).  All later models
+  should use CONFIG_ADB_PMU instead.
+
+  If unsure say Y.
