Semaphore to mutex conversion.
The conversion was generated via scripts, and the result was validated
automatically via a script as well.

It's not like this has changed significantly, and probably never will.
Reduce some bootup dmesg noise.

I spotted 'main_lock' whilst grovelling through a vmlinux with objdump.
Even if it is static, it's a horrible name.

Intel Xeons
They report 40bit, but only have 36bits of physical address space.
This caused problems with setting up the correct masks for MTRR.
CPUID workaround for steppings 0F33h(supporting x86) and 0F34h(supporting x86
and EM64T). Detail info can be found at:

There has been some discuss about solving the SMP MTRR suspend/resume
breakage, but I didn't find a patch for it. This is an intent for it. The
basic idea is moving mtrr initializing into cpu_identify for all APs (so it
works for cpu hotplug). For BP, restore_processor_state is responsible for
restoring MTRR.

It doesn't make sense to only do this only for AMD K8.
This would support future CPUs with extended address spaces properly.

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!
