[PATCH 0/3] Fix preemption errors in watchpoints

[Benjamin Gray <bgray@linux.ibm.com>]

When enabling debug config options relating to preemption, several bugs
appear in the kernel log. With this series applied, the breakpoint code
no longer prints bugs when running the powerpc/ptrace selftests.

Benjamin Gray (3):
  powerpc/watchpoints: Disable preemption in thread_change_pc()
  powerpc/watchpoint: Disable pagefaults when getting user instruction
  powerpc/watchpoints: Annotate atomic context in more places
