These are the generic bits needed to enable reliable stack traces based
on Dwarf2-like (.eh_frame) unwind information. Subsequent patches will
enable x86-64 and i386 to make use of this.
Thanks to Andi Kleen and Ingo Molnar, who pointed out several possibilities
for improvement.

In x86_64 architecture, if device driver with msi function
gets 0xee vector by assign_irq_vector() function, system will
crash if this interrupt happens. It is because 0xee interrupt
entry is empty. This patch modifies this. This patch is based
on 2.6.17-rc6.

- Rename the GART_IOMMU option to IOMMU to make clear it's not
just for AMD
- Rewrite the help text to better emphatise this fact
- Make it an embedded option because too many people get it wrong.
To my astonishment I discovered the aacraid driver tests this
symbol directly. This looks quite broken to me - it's an internal
implementation detail of the PCI DMA API. Can the maintainer
please clarify what this test was intended to do?

Fix a potential deadlock scenario introduced by io_apic.c's new vector_lock
on i386 and x86_64.
Found by the locking correctness validator. The patch was boot-tested on
x86. For details of the deadlock scenario, see the validator output:
======================================================
[ BUG: hard-safe -> hard-unsafe lock order detected! ]
------------------------------------------------------
idle/1 [HC0[0]:SC0[0]:HE0:SE1] is trying to acquire:
(msi_lock){....}, at: [<c04ff8d2>] startup_msi_irq_wo_maskbit+0x10/0x35
and this task is already holding:
(&irq_desc[i].lock){++..}, at: [<c015b924>] probe_irq_on+0x36/0x107
which would create a new lock dependency:
(&irq_desc[i].lock){++..} -> (msi_lock){....}
but this new dependency connects a hard-irq-safe lock:
(&irq_desc[i].lock){++..}
... which became hard-irq-safe at:

[<c015aff5>] __do_IRQ+0x3d/0x113
[<c01062d3>] do_IRQ+0x8c/0xad
to a hard-irq-unsafe lock:
(vector_lock){--..}
... which became hard-irq-unsafe at:

It was originally added for 2.4 oprofile, but 2.6 oprofile doesn't
need that anymore. Shouldn't be any use in tree anymore and it doesn't
make much sense to export the ia32 syscalls when the main syscalls
are not exported.
I think Adrian Bunk asked for removing it several times.
Also included hunk from Adrian to remove the .globl ia32_sys_call_table

- 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).

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.

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.

Enable some hwmon drivers as modules and tulip and stack unwinding
Kernel image should be somewhat bigger now because of the unwind
information being included, but you'll get exact backtraces for that.

binfmt_flat.c calls set_personality with PER_LINUX as the personality.
On the arm architecture this results in the program running in 26bit
usermode. PER_LINUX_32BIT should be used instead. This doesn't affect
other architectures that use binfmt_flat.

Here is a patch to the system call handling for 5307/5272/etc to:
- fix the strace support (one tested the wrong bit)
- 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.

Remove list of fixed clock frequency options used for configuring master
clock, and make field an int. Much more flexible this way, no need to add
more options for every new used freqency.

A cleanup of m68knommu/kernel/setup.c :
- No need to initialize global pointers to NULL, they will have that value
automatically, and they eat up space in my data segment image in FLASH.
- Remove get_cpuinfo. It has been replaced by show_cpuinfo.
