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

From: Li Zhong
Date: Mon May 13 2013 - 01:21:52 EST


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
