Pull x86 TDX updates from Dave Hansen:
 "There are a few cleanups, and some changes that should allow TDX and
  kexec to coexist nicely.

  The biggest change, however, is support for updating the TDX module
  after boot, just like CPU microcode. TDX users really want this
  because it lets them do security updates without tearing things down
  and rebooting.

   - Add TDX module update support

   - Make kexec and TDX finally place nice together

   - Put TDX error codes into a single header"
