    ARM: kprobes: make more tests conditional · 5c5b06c3
    Arnd Bergmann authored
    The mls instruction is not available in ARMv6K or below, so we
    should make the test conditional on at least ARMv7. ldrexd/strexd
    are available in ARMv6K or ARMv7, which we can test by checking
    the CONFIG_CPU_32v6K symbol.
