Appended patch adds the support for Intel dual-core detection and displaying
the core related information in /proc/cpuinfo.
It adds two new fields "core id" and "cpu cores" to x86 /proc/cpuinfo and the
"core id" field for x86_64("cpu cores" field is already present in x86_64).
Number of processor cores in a die is detected using cpuid(4) and this is
documented in IA-32 Intel Architecture Software Developer's Manual (vol 2a)
(http://developer.intel.com/design/pentium4/manuals/index_new.htm#sdm_vol2a)
This patch also adds cpu_core_map similar to cpu_sibling_map.
Slightly hacked by AK.

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.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
