[Qemu-devel] [PATCH 1/2] seccomp: Whitelist cacheflush since 2.2.0 not 2.2.3

[James Hogan <james.hogan@imgtec.com>]

The cacheflush system call (found on MIPS and ARM) has been included in
the libseccomp header since 2.2.0, so include include it back to that
version. Previously it was only enabled since 2.2.3 since that is when
it was enabled properly for ARM.

This will allow seccomp support to be enabled for MIPS back to
libseccomp 2.2.0.
