[RFC PATCH v3 0/5] powerpc: Support context tracking for Power pSeries

[Li Zhong]

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.

v3:

This version is mainly a rebasing, against 3.10-rc1, also as the common code 
to handle the exception are pulled into 3.10, so there is no dependency on 
tip tree. So patch #2 and #6 in previous version_2 is merged together. 

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
