[FFmpeg-devel] [PATCH] tests/checkasm: add exclude_guest for non-x86 linux perf

[J. Dekker]

exclude_guest is currently only supported on x86. However, not
specifying 'exclude_guest' implies that you can count guest events
should you run one. This creates an ABI issue whereby some non-x86
kernels require specifying exclude_guest = 1 explicitly.
