[RFC PATCH 20/55] KVM: x86: allow KVM_TRANSLATE on plane vCPU fds

[David Woodhouse]

From: David Woodhouse <dwmw@xxxxxxxxxxxx>

The VMM needs to translate guest virtual addresses in the context of a
specific plane to implement HvCallTranslateVirtualAddress, which a
higher VTL uses to resolve a lower VTL's buffer addresses.
KVM_TRANSLATE already works on any vCPU; permit it on plane fds too.
