2017-11-05update aarch64 hwcap.h for linux v4.11Szabolcs Nagy1-0/+2
new hwcap bits were added in kernel commits 77c97b4ee21290f5f083173d957843b615abbff2 f92f5ce01ee6a6a86cbfc4e3b0d18529c302b1ea
2016-10-20add bits/hwcap.h and include it in sys/auxv.hSzabolcs Nagy1-0/+11
aarch64, arm, mips, mips64, mipsn32, powerpc, powerpc64 and sh have cpu feature bits defined in linux for AT_HWCAP auxv entry, so expose those in sys/auxv.h it seems the mips hwcaps were never exposed to userspace neither by linux nor by glibc, but that's most likely an oversight.
