(Resending the pachset as the v9 sent on 6/23/2023 didn't draw much attention)
The two patches are based on today's tip.git's master branch.
Note: the two patches don't apply to the current x86/tdx branch, which
doesn't have commit 75d090fd167a ("x86/tdx: Add unaccepted memory support").
As Dave suggested, I moved some local variables of tdx_map_gpa() to
inside the loop. I added Sathyanarayanan's Reviewed-by.
Please review.
FWIW, the old versons are here:
