This fixes regression introduced in 113134fcbca83619be4c68d0ca66db6093777b5d
Intel Tiger platforms hang when calling SAL_GET_PHYSICAL_ID_INFO
instead of properly returning -1 for unimplemented, so add a
version check.
SGI Altix platforms have an incorrect SAL version hard-coded into
their prom -- they encode 2.9, but actually implement 3.2 -- so
fix it up and allow ia64_sal_get_physical_id_info to keep
working.

Since kvm/module needs to use some unexported functions in kernel,
so export them with this patch.

Remove in-source externs, linux/init.h is included in all cases.
This is a fixups for "Dynamic kernel command-line" patch.
It also includes some uml __init fixups so that we can __initdata also its
command_line.

1. Rename saved_command_line into boot_command_line.
2. Set command_line as __initdata.
[akpm@osdl.org: move some declarations to the right place]

The check to see if the firmware drops interrupts during a
SAL_CACHE_FLUSH is done to early in the boot. SAL_CACHE_FLUSH expects
to be able to make PAL calls in virtual mode, on some cell based
machines a fault occurs causing a MCA. This patch moves the check
after mmu_context_init so the TLB and VHPT are properly setup.

Sorry I didn't notice earlier, but that BUG_ON triggers for me on the
simulator. AFAICS the mask for itv is set in cpu_init(), which comes
after sal_init(). Consequently on the simulator the itv still has its
start value of zero. I've probably missed something, but I wonder why
at this stage of the boot you even need to save and restore the itv?

If SAL_CACHE_FLUSH drops interrupts, complain about it and fall back to
using PAL_CACHE_FLUSH instead.
This is to work around a defect in HP rx5670 firmware: when an interrupt
occurs during SAL_CACHE_FLUSH, SAL drops the interrupt but leaves it marked
"in-service", which leaves the interrupt (and others of equal or lower
priority) masked.

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!
