Merge up to 2.6.26
Merge of 2.6.x-xfs-melb:linux:31804b by kenmcd.

/*
 * linux/asm-sparc64/reg.h
 * Layout of the registers as expected by gdb on the Sparc
 * we should replace the user.h definitions with those in
 * this file, we don't even use the other 
 * -miguel
 *
 * The names of the structures, constants and aliases in this file
 * have the same names as the sunos ones, some programs rely on these
 * names (gdb for example).
