    metag: OProfile support · 00e6c923
    James Hogan authored
    Add OProfile support for metag, using the perf backend, and falling back
    to generic timer based sampling if perf counter interrupt support is
    disabled.
    
    The oprofile code prepends "metag/" to the perf pmu name to give
    "metag/meta2" which is more consistent with other oprofile arch names.
    
    The backtrace code makes use of <asm/stacktrace.h> for kernel
    backtracing, and a simple frame pointer walk for userland backtracing.
