Jeremy Fitzhardinge eba0045ff8 x86/paravirt: add a pgd_alloc/free hooks 
Add hooks which are called at pgd_alloc/free time.  The pgd_alloc hook
may return an error code, which if non-zero, causes the pgd allocation
to be failed.  The hooks may be used to allocate/free auxillary
per-pgd information.
