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. "
