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
