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.
