x86 Page Attribute Table (PAT) MSR support.
...
Reconfigure PAT to permit write-combining memory type to be assigned
on a page-by-page basis. Changes PWT and PCD bit combinations in page
table entries so that they correspond to the following format:
PAT
|PCD
||PWT
|||
000 WB Write Back (WB)
001 WC Write Combining (WC)
010 UC- Uncached (UC-)
011 UC Uncacheable (UC)

...
MSR_IA32_MISC_ENABLE, MSR_IA32_PERF_CTL and MSR_IA32_ENERGY_PERF_BIAS
are responsible for performance settings, this change enables McKernel
to perform on par with Linux when running the fwq benchmark.

fix PTRACE_PEEKUSER, PTRACE_POKEUSER, PTRACE_GETREGS.
...
support PTRACE_SETREGS.
In struct process, add 'unsigned long *ptrace_debugreg', instead of 'struct user *userp'.
debug registers are read/written from/to ptrace_debugreg, save/restore in schedule().
most general registers are proc->uctx.
fs_base is proc->thread.tlsblock_base.
gs_base,ds,es,fs,gs and orig_rax are uncompleted.
other members in 'struct user' are ignored, same as Linux implementation.
