 - Kconfig cleanups:
    - enable DMA_NONCOHERENT, DMA_COHERENT or DMA_IP27 via reverse dependencies
    - untangle VRC4171 / VRC4173 selection
    - R10000 support enables PREFETCH
    - SEAD needs IRQ_CPU
 - Update defconfig against latest Kconfig files.
 - Fix computation of return address if syscall number was out of range
 - Add power managment hooks in signal code.
 - Don't try to handle signals when previous context was not in user mode.
 - Fix serial interface setup for VR41xx systems.
 - Build fixes after CLEAR_BITMAP changed name.
 - Removes bogus comment from <asm/checksum.h>
 - <asm/hdreg.h> is dead.
 - Start collecting common definitions for PMON firmware in <asm/pmon.h>
 - Define ARCH_MIN_TASKALIGN to 8; we have 64-bit members even on 32-bit
   kernels if we're running on MIPS II or better.

From: Ralf Baechle <ralf@linux-mips.org>

- more work on resurrecting AMD Alchemy platforms
- cleanup of unnecessary <asm/pgalloc.h> inclusions
- update default config files
- cleanup 32-bit compat ioctl code
- support for Montum Jaguar ATX
- workarounds for early revs of the RM9000
- fixes for RM5000 and RM7000 cache handling
- add support for PMC-Sierra Yosemite eval board
- further cleanup and bugfixes for SGI IP27
- make LASAT and VR41xx build and work in 2.6
- improved SGI IP32 support
- plenty of small fixes

Below following 125547 lines of patches, all to arch/mips and
include/asm-mips.  I'm going to send the remaining stuff of which the one
or other bit may need to be discussed in smaller bits.

Here's another MIPS update.  The patch is huge because it completly
folds mips64 into mips, thereby eleminating 41010 lines of code.

initialized size in consideration.

Update defconfig files throughout kernel. Replacing CONFIG_NTFS_RW
with CONFIG_NTFS_DEBUG as the former no longer exists while the
latter now exists.

  - Alan Cox: big driver/mips sync
  - Andries Brouwer, Christoph Hellwig: more gendisk fixups
  - Tobias Ringstrom: tulip driver workaround for DC21143 erratum

  - David Miller: sparc rw semaphores moved over
  - Alan Cox: yet more resyncs
  - NIIBE Yutaka: Super-H driver update
  - David Howells: more rw-sem cleanups, updates
  - USB updates
  - Al Viro: filesystem init cleanup
