- Change CPUID to match the old Ki386Cpuid and take 4 output arguments instead of an array. This way we save some stack when using a dummy cpuid for synchronization and can query only the registers we want in the case we don't want all 4.
- Simplify Ke386GetTr and Ke386GetLocalDescriptorTable to return by value instead of reference.
- Make RDMSR smaller by making it fastcall as rdmsr takes its argument in ecx.
- Fix KiGetCacheInformation -- it only handled the Intel and AMD case.
- Replace Ke386HaltProcessor with __halt.
- KiHaltProcessorDpcRoutine: Always halt the processor for the architectures we support for consistency.
- Clean up x86 and PPC headers from deprecated stuff.
- Fix broken LOCK undefine in v86m_sup.S -- LOCK is used both in a macro and the code, so only undefine it where required and redefine it after it is used (this worked because LOCK was interpreted as lock).

Get rid of KeArch*:
- Rename KeArchInitThreadWithContext to KiInitializeContextThread and use the same name for all architectures.
- Kill KeArchHaltProcessor. Use __halt and KeArmHaltProcessor directly instead.
- Use Ke386FnInit instead of KeArchFnInit -- it is only used for x86.
