Merge tag 'x86_tdx_for_6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 tdx updates from Dave Hansen:

 - Fix a race window where load_unaligned_zeropad() could cause a fatal
   shutdown during TDX private<=>shared conversion

   The race has never been observed in practice but might allow
   load_unaligned_zeropad() to catch a TDX page in the middle of its
   conversion process which would lead to a fatal and unrecoverable
   guest shutdown.

 - Annotate sites where VM "exit reasons" are reused as hypercall
   numbers.
