Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc
Pull sparc fixes from David Miller:
"Two sparc64 perf bug fixes and add a sysrq facility so I can diagnose
these kinds of problems more quickly in the future."
* git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc:
sparc64: Fix bit twiddling in sparc_pmu_enable_event().
sparc64: Add global PMU register dumping via sysrq.
sparc64: Like x86 we should check current->mm during perf backtrace generation.
