bf12a5c45e Introduction of write-combined memory type mappings.
Introduction of VR_WRITE_COMBINED, PTATTR_WRITE_COMBINED and modification
to the memobj's get_page() interface so that Linux communicates back mapping
flags (such as write-combined).

ea5681232e 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)

e4f47df3c3 initialize pstate, turbo mode and power/performace bias MSR registers
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.

c3ade864d9 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.

19fa391d4f Implement vfork system call
It's implemented by making it issue clone system call internally with
the arguments of (SIGCHLD, 0, 0, 0, 0). The feature in which the caller
of vfork blocks until the child issues exit/execve is not implemented.
Refer to #233.
