perf/x86/amd: AMD support for bp_len > HW_BREAKPOINT_LEN_8
Implement hardware breakpoint address mask for AMD Family 16h and
above processors. CPUID feature bit indicates hardware support for
DRn_ADDR_MASK MSRs. These masks further qualify DRn/DR7 hardware
breakpoint addresses to allow matching of larger addresses ranges.
Valuable advice and pseudo code from Oleg Nesterov <oleg@redhat.com>
