Commit Message

David Matlack Dec. 8, 2022, 7:38 p.m. UTC 
Introduce a new config option to gate support for the common TDP MMU.
This will be used in future commits to avoid compiling the TDP MMU code
and avoid adding fields to common structs (e.g. struct kvm) on
architectures that do not support the TDP MMU yet.

No functional change intended.
