[Daniel Berrange <1815889@bugs.launchpad.net>]

FYI the QEMU change merged in the following pull request changed to
return an EPERM errno for the thread affinity syscalls:

    * remotes/otubo/tags/pull-seccomp-20190327:
      seccomp: report more useful errors from seccomp
      seccomp: don't kill process for resource control syscalls
    
    Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

IOW, mesa's usage of this syscalls will still be blocked, but it will no
longer kill the process.
