Some cached pages may actually be overlays on guest memory that have a
fixed HVA within the VMM. It's pointless to invalidate such cached
mappings if the overlay is moved so allow a cache to be activated directly
with the HVA to cater for such cases. A subsequent patch will make use
of this facility.

Btw, I think you have falsified some Reviewed-by: tags on the rest of
the series. Remember, if they aren't literally cut and pasted, the
magic gets lost. Just the same as Signed-off-by: tags. Never type them
for someone else.

Indeed. They were all copied and pasted.

I'm prepared to believe my fingers betrayed me and autocompleted
@infradead.org for one or two of them when I meant to use the @amazon
address, but surely not *all* of them that I reviewed last time round?


Hmm. I guess I must have cut'n'pasted from the wrong place then. I'll be more careful.
