- Factor out the duplicated access/cache code into a single file
* Shared between i386/x86-64.
- Share flush code between AGP and IOMMU
* Fix a bug: AGP didn't wait for end of flush before
- Drop 8 northbridges limit and allocate dynamically
- Add lock to serialize AGP and IOMMU GART flushes
- Add PCI ID for next AMD northbridge
- Random related cleanups
The old K8 NUMA discovery code is unchanged. New systems
should all use SRAT for this.

A trivial change to have gart_unmap_sg call gart_unmap_single directly,
instead of bouncing through the dma_unmap_single wrapper in
dma-mapping.h.
This change required moving the gart_unmap_single above gart_unmap_sg,
and under gart_map_single (which seems a more logical place that its
current location IMHO).

Previously we would just silently provide 64 bit services
for this to 32bit processes.
I also added all the other cases explicitely to the ptrace
compat wrapper to make sure this doesn't happen again.
And removed one bogus check in the wrapper.

Allow search for a contiguous block of iommu space to cross the next_bit
marker if we have already committed ourselves to flushing the gart.
There shouldn't be any reason why we'd restrict the search.

Changes are largely identical to the i386 version:
* alternative #define are moved to the new alternative.h file.
* one new elf section with pointers to the lock prefixes which can be
nop'ed out for non-smp.
* two new elf sections simliar to the "classic" alternatives to
replace SMP code with simpler UP code.
* fixup headers to use alternative.h instead of defining their own
LOCK / LOCK_PREFIX macros.
The patch reuses the i386 version of the alternatives code to avoid code
duplication. The code in alternatives.c was shuffled around a bit to
reduce the number of #ifdefs needed. It also got some tweaks needed for
x86_64 (vsyscall page handling) and new features (noreplacement option
which was x86_64 only up to now). Debug printk's are changed from
compile-time to runtime.
Loosely based on a early version from Bastian Blank <waldi@debian.org>

Intel systems report the cache level data from CPUID 4 in sysfs.
Add a CPUID 4 emulation for AMD CPUs to report the same
information for them. This allows programs to read this
information in a uniform way.
The AMD way to report this is less flexible so some assumptions
are hardcoded (e.g. no L3)

vSMPowered systems use apic_cluster too. Forcing apic_physflat works
on these systems too, but only if we change phys_pkg_id to use
hard_smp_prcoessor_id() instead of cpuid_ebx. I am guessing other
multichassi cluster systems would need this too.

- make all system calls a little bit faster by inlining set_esp0 and
supporting ENOSYS out of the critical path.
- remove extraneous spaces

This patch solve a bug triggered by execvp (this function use calloc to
store the argument list and gcc 3.4.x align the stack to word, not to dword).
This situation aren't related to signal handling and all 2.6.x have the bug.
On ColdFire targets we must force the stack to be aligned.
