[GIT PULL] x86/tdx for 7.3-rc1

[Dave Hansen]

Hi Linus,

Please pull some x86/tdx changes for 7.3-rc1. TDX guests cause #VE
exceptions whenever they do port I/O. The guest then does some
instruction decoding and makes a call up to the host for help. That
decoding had a couple of bugs.

Fix those bugs. Use an existing and now shared KVM helper for one
of them.
