Add it to the whitelist. Signed-off-by: Andrew Jones --- I'm not sure about the priority selection. Maybe cacheflush gets used frequently enough that it deserves a higher one? This patch isn't really necessary yet due to ae6e8ef11e6c: "Revert seccomp tests that allow it to be used on non-x86 architectures", which we can't revert until libseccomp has released a fix for arm-specific syscall symbol naming, but when linking to a patched libseccomp and reverting ae6e8ef11e6c, then this patch allows guests to boot with '-sandbox on'.
