valgrind currently does not know anything about the CPUID flag added to the HWCAP auxv entry in kernel 4.11+
At runtime it will fails like this: ARM64 front end: branch_etc disInstr(arm64): unhandled instruction 0xD5380001 disInstr(arm64): 1101'0101 0011'1000 0000'0000 0000'0001 ==2082== valgrind: Unrecognised instruction at address 0x4014e64. This patch is a workaround by masking all HWCAP.
