Merge branch 'perf/core-v3' of git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks into perf/hw_breakpoints

Pull AMD range breakpoints support from Frederic Weisbecker:

" - Extend breakpoint tools and core to support address range through perf
    event with initial backend support for AMD extended breakpoints.

    Syntax is:

           perf record -e mem:addr/len:type

    For example set write breakpoint from 0x1000 to 0x1200 (0x1000 + 512)

           perf record -e mem:0x1000/512:w

 - Clean up a bit breakpoint code validation

 It has been acked by Jiri and Oleg. "
