KVM: Make paravirt tlb flush also reload the PAE PDPTRs
The paravirt tlb flush may be used not only to flush TLBs, but also to reload the four page-directory-pointer-table entries, as it is used as a replacement for reloading CR3. Change the code to do the entire CR3 reloading dance instead of simply flushing the TLB. Cc: stable@kernel.org Signed-off-by: Avi Kivity <avi@redhat.com>
