    Subject[PATCH v8 3/5] arm64: replace -pg with CC_FLAGS_FTRACE in mm/kasan Makefile
    Date
    From
      In preparation for arm64 supporting ftrace built on other compiler
    options, let's have makefiles remove the $(CC_FLAGS_FTRACE)
    flags, whatever these may be, rather than assuming '-pg'.

    There should be no functional change as a result of this patch.
