Subject: KVM: x86: enable TDP MMU by default
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=71ba3f3189c78f756a659568fb473600fd78f207;p=linux.git

KVM: x86: enable TDP MMU by default

With the addition of fast page fault support, the TDP-specific MMU has reached
feature parity with the original MMU.  All my testing in the last few months
has been done with the TDP MMU; switch the default on 64-bit machines.
