2.5.44-mm3

[Andrew Morton <akpm@digeo.com>]

url: http://www.zip.com.au/~akpm/linux/patches/2.5/2.5.44/2.5.44-mm3/

. Lots of little fixes.

. Dropped the patch which allocates each CPU's per-cpu memory separately.
  That's over in experimental/ and has been reworked to use alloc_pages_node(),
  if anyone's interested.

. Badari has redone the patch which permits finer-than-fs-blocksize
  direct IO.

. Patch from Rusty permits NR_CPUS > sizeof(unsigned long)*8.

. An enormous patch from Adam Richter against the loop driver.  It needs
  work, but let's get that under test.

. Added Ingo's put-page-offset-into-ptes-for-mmap patch.  That's ia32-only
  at present so I've uploaded a 2.5.44-mm3-non-ia32.gz rollup as well,
  which doesn't have that one.

. Update to the patch management scripts is in
  http://www.zip.com.au/~akpm/linux/patches/patch-scripts-0.2/
  This includes a new command "pstatus" from Stephen Cameron which
  provides a status summary of all your patches.

  User testimonials include "neat", "it encourages you to make
  fine-grained patches" and "I made 30 patches and almost all of
  them were merged!".
