Impact: fix /proc/cpuinfo output on x86/Voyager

| x86: convert cpuinfo_x86 array to a per_cpu array
We've had an extra field in cpuinfo_x86 which is cpu_index.
Unfortunately, voyager has never initialised this, although the only
noticeable impact seems to be that /proc/cpuinfo shows all zeros for
the processor ids.
Anyway, fix this by initialising the boot CPU properly and setting the
index when the secondaries update.

| x86, xsave: enable xsave/xrstor on cpus with xsave support
Which deliberately expose boot cpu dependence to pieces of the system,
I think it's time to explicitly have a variable for it to prevent this
continual misassumption that the boot CPU is zero.

Impact: allow /dev/mem mmaps on non-PAT CPUs/platforms
Fix mmap to /dev/mem when CONFIG_X86_PAT is off and CONFIG_STRICT_DEVMEM is
off
mmap to /dev/mem on kernel memory has been failing since the
introduction of PAT (CONFIG_STRICT_DEVMEM=n case). Seems like
the check to avoid cache aliasing with PAT is kicking in even
when PAT is disabled. The bug seems to have crept in 2.6.26.
This patch makes sure that the mmap to regular
kernel memory succeeds if CONFIG_STRICT_DEVMEM=n and
PAT is disabled, and the checks to avoid cache aliasing
still happens if PAT is enabled.

| x86: move prefill_possible_map calling early
prefill_possible_mask() was hidden under CONFIG_HOTPLUG_CPU rendering
it invisitble to voyager. Since this commit it's exposed, but not
provided by the voyager subarch, so add a dummy stub to fix the link

Impact: fix AMD Family 11h boot hangs / USB device problems
The AMD Fam11h CPUs have a K8 northbridge. This northbridge is different
from other family's because it lacks GART support (as I just learned).
But the kernel implicitly expects a GART if it finds an AMD northbridge.
Fix this by removing the Fam11h northbridge id from the scan list of K8
northbridges. This patch also changes the message in the GART driver
about missing K8 northbridges to tell that the GART is missing which is
the correct information in this case.

Impact: fix kdump crash on 32-bit sparsemem kernels
Since linux-2.6.27, kdump has failed on i386 sparsemem kernel.
1st-kernel gets a panic just before switching to 2nd-kernel.
The cause is that a kernel accesses invalid mem_section by
page_to_pfn(image->swap_page) at machine_kexec().
image->swap_page is allocated if kexec for hibernation, but
it is not allocated if kdump. So if kdump, a kernel should
not access the mem_section corresponding to image->swap_page.
The attached patch fixes this invalid access.

Impact: fix guest kernel boot crash on certain configs
Recent i686 2.6.27 kernels with a certain amount of memory (between
736 and 855MB) have a problem booting under a hypervisor that supports
batched mprotect (this includes the RHEL-5 Xen hypervisor as well as
any 3.3 or later Xen hypervisor).
The problem ends up being that xen_ptep_modify_prot_commit() is using
virt_to_machine to calculate which pfn to update. However, this only
works for pages that are in the p2m list, and the pages coming from
change_pte_range() in mm/mprotect.c are kmap_atomic pages. Because of
this, we can run into the situation where the lookup in the p2m table
returns an INVALID_MFN, which we then try to pass to the hypervisor,
which then (correctly) denies the request to a totally bogus pfn.
The right thing to do is to use arbitrary_virt_to_machine, so that we
can be sure we are modifying the right pfn. This unfortunately
introduces a performance penalty because of a full page-table-walk,
but we can avoid that penalty for pages in the p2m list by checking if
virt_addr_valid is true, and if so, just doing the lookup in the p2m
table.
The attached patch implements this, and allows my 2.6.27 i686 based
guest with 768MB of memory to boot on a RHEL-5 hypervisor again.
Thanks to Jeremy for the suggestions about how to fix this particular
issue.

Canonicalize a few remaining header guards, with the exception for
those which are still in subarchitecture directories.

Drop double underscores from header guards in arch/x86/include. They
are used inconsistently, and are not necessary.

Change header guards named "ASM_X86__*" to "_ASM_X86_*" since:
a. the double underscore is ugly and pointless.
b. no leading underscore violates namespace constraints.

The variable apic_flat references
the function __init flat_acpi_madt_oem_check()
This is harmless, because the .acpi_madt_oem_check is only called
during init time. But we keep the function pointer around in a .data
function pointer template, so it's better we do not keep that stale
- so mark this function non-__init.

Hi all,
Wrong usage of 2nd parameter in reserve_early call.
66/75: reserve_early(start_bad, last_bad - start_bad, "BAD RAM");
^^^^^^^^^^^^^^^^^^^^
The correct way is to use 'end' address and not 'size'.
As a bonus a fix to the printk format.
