[PATCH] paravirt: Add MMU virtualization to paravirt_ops
Add the three bare TLB accessor functions to paravirt-ops. Most amusingly,
flush_tlb is redefined on SMP, so I can't call the paravirt op flush_tlb.
Instead, I chose to indicate the actual flush type, kernel (global) vs. user
(non-global). Global in this sense means using the global bit in the page
table entry, which makes TLB entries persistent across CR3 reloads, not
global as in the SMP sense of invoking remote shootdowns, so the term is
confusingly overloaded.
AK: folded in fix from Zach for PAE compilation
