[RFC PATCH v4 0/5] powerpc: Support context tracking for Power pSeries

[Li Zhong <zhong@linux.vnet.ibm.com>]

These patches try to support context tracking for Power arch, beginning with
64-bit pSeries. The codes are ported from that of the x86_64, and in each
patch, I listed the corresponding patch for x86.

v4:
fixed some cosmetic issues suggested by Ben.

Li Zhong (5):
  powerpc: Syscall hooks for context tracking subsystem
  powerpc: Exception hooks for context tracking subsystem
  powerpc: Exit user context on notify resume
  powerpc: Use the new schedule_user API on userspace preemption
  powerpc: select HAVE_CONTEXT_TRACKING for pSeries
