SubjectRe: [PATCH v3 2/3] perf arm64: Generate system call table from asm/unistd.h

I'm going with this quick hack applied so that I can pass all tests,
feel free to provide an alternative patch that makes
tools/include/uapi/asm-generic/unistd.h be used when included by
tools/arch/arm64/include/uapi/asm/unistd.h, that I haven't tried to do
and looks the right fix.
