  Current linux_fooaffinity() emulation fails, as the FreeBSD affinity
  syscalls expect the bitmap size in the range from 32 to 128. Old glibc
  always assumed size 1024, while newer glibc searches for approriate
  size, starting from 1024 and going up.
  
  For now, use FreeBSD size of cpuset_t for bitmap size parameter and
  return EINVAL if length of user space bitmap less than our size of
  cpuset_t.
