Pull generic kernel entry/exit code from Thomas Gleixner:
 "Generic implementation of common syscall, interrupt and exception
  entry/exit functionality based on the recent X86 effort to ensure
  correctness of entry/exit vs RCU and instrumentation.

  As this functionality and the required entry/exit sequences are not
  architecture specific, sharing them allows other architectures to
  benefit instead of copying the same code over and over again.

  This branch was kept standalone to allow others to work on it. The
  conversion of x86 comes in a seperate pull request which obviously is
  based on this branch"
