[PATCH 1/2] KVM: Make paravirt tlb flush also reload PAE PDPTEs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
