[Qemu-devel] [PATCHv3 0/2] seccomp: remove unused syscalls - for 1.6

In this small patch series I basically:

  v3 update:
  - reincluded getrlimit(), it's used by Xen.

  v2 update:
  - set libseccomp 2.1.0 as requirement on configure script.
  - reincluded setrlimit() (used by Xen) and removed sendfile64() from
    the whitelist.

  1) Remove the ifdef's for the (not so) new libseccomp version that does a
  best effort and translates x86_32 syscalls into x86_64 when possible.

  2) Remove unused syscalls on the seccomp whitelist. For that removal, I've 
  running several instances of Qemu using a script written on top of
  virt-test[0]. After some weeks testing I could come up with this small list,
  and safely remove them without breaking anything.
