[PATCH] Extended attributes syscalls for powerpc (updated, re-send)

Hi Paul,

This is a re-send of an updated patch for extended attributes syscall
allocation for powerpc, Linus has added a syscall (tkill) to the
powerpc arch in 2.5.4 so my patch had to be adjusted and the
allocation has changed.  Since Linus appears to randomly keep powerpc
syscalls in sync with other architectures I believe it is imperative
that this patch be sent along to him ASAP so we don't have to keep
reallocating these syscalls and thus breaking userspace along the way.

Linus has merged the Extended attributes API from Andreas Gruenbacher
and Nathan Scott (SGI) into 2.5.3, and added the i386 syscalls.

By request of Nathan I have created the attached patch to add the
syscalls to the powerpc arch.

This patch allocates syscalls 209-220, if you have no problems with
this allocation could you merge this patch with the powerpc 2.5
kernel tree?  The sooner this can happen the better as Nathan is
working on getting the userspace utilities fixed to use the official
API and official syscall numbers, therefore we need the powerpc
syscall numbers reserved ASAP so the userspace utilities can support
the powerpc architecture.


This patch, and a version against the Linus 2.5.4 tree is also
available at:
