2.5.43-m3

url: http://www.zip.com.au/~akpm/linux/patches/2.5/2.5.42/2.5.42-mm3/

- drop SARD again.  It broke RAID0.  Al is working on converting SARD
  to a driverfs interface.

- fix the crashing in the timer code.

- went on an uninlining rampage and shrunk the kernel image by 10k or so.

- merge up the ext2/3 extended attribute code, convert that to use
  the slab shrinking API in Linus's current tree.

- add a new timer API function:

	add_timer_on(struct timer_list *timer, int cpu);

  to start a timer on a different CPU.

- rework the slab shrinking code to use add_timer_on(), so we don't
  need to launch a kernel thread just to get a timer onto another CPU.

- Add Ingo's current remap_file_pages() patch.  I had to renumber his
  syscall from 253 to 254 due to a clash with the oprofile syscall.

This will only work on ia32.  To test on other architectures, please

Trivial patch for the "too chicken to enable xattrs for now" case, but I
need this to compile:

Please add this to include/linux/errno.h instead:

#define ENOTSUP EOPNOTSUPP      /* Operation not supported */

ENOTSUPP is distinct from (EOPNOTSUPP = ENOTSUP)

(Yes, it's a mess.)

You explained some time ago that it is not posix-compliant to have
two errnos with the same numerical value.  So please do it right..

Actually, what I've been doing is just using EOPNOTSUPP directly in
the patches; I just missed those error returns in ext[23]_xattr.h.
