    perf: Drop the skip argument from perf_arch_fetch_regs_caller · b0f82b81
    Frederic Weisbecker authored
    Drop this argument now that we always want to rewind only to the
    state of the first caller.
    It means frame pointers are not necessary anymore to reliably get
    the source of an event. But this also means we need this helper
    to be a macro now, as an inline function is not an option since
    we need to know when to provide a default implentation.
