Bruce,

Attached is my equivalent implementation of ATOMIC_PT_UPDATE. Notice that I
changed the name to MMU_PT_UPDATE_PRESERVE_AD, also that I removed a bunch
of code duplication albeit at the expense of passing yet another parameter
around.

Could you rev your Linux patch and give it a spin?

 Thanks,
 Keir
