13 Originally virtualization was slow on grsec/pax with either uderef or
14 kernexec enabled. Pipacs overcame this limitation in 3.5.4-r1 and
15 overcame a memory commit issue kvm was having in 3.5.4-r2. He overcame
16 it using nested page tables on newer CPUs, which means older CPUs will
17 likely still be slow.
