[PATCH] i386: Use loaddebug macro consistently
This moves the macro loaddebug from asm-i386/suspend.h to
asm-i386/processor.h, which is the place that makes sense for it to be
defined, removes the extra copy of the same macro in
arch/i386/kernel/process.c, and makes arch/i386/kernel/signal.c use the
macro in place of its expansion.
This is a purely cosmetic cleanup for the normal i386 kernel. However, it
is handy for Xen to be able to just redefine the loaddebug macro once
instead of also changing the signal.c code.
