Currently kexec() support and TDX host are muturally exclusive in the

work together and can be enabled at the same time in the Kconfig.

This follows Dave's suggestion to add the CC_ATTR_HOST_MEM_INCOHERENT
attribute to unify both Intel and AMD, instead of having Intel/AMD
specific checks around [1].

Hi Tom,

I've tested on my TDX testig machine but I don't have AMD machine to
test.  I highly appreciate if you or any AMD guy can help to review
and/or test this series to make sure I didn't break anything.

Hi Kai,

I'm adding Ashish to the thread to take a look at this as he's been focusing on kexec related things recently.


Thanks Tom.

Hi Ashish,

I appreciate if you can help to review and test the first patch. Thanks!
