Subject[PATCHv2 0/3] x86/tdx: Fix one more load_unaligned_zeropad() issue
Date
During review of TDX guests on Hyper-V patchset Dave pointed to the
potential race between changing page private/shared status and
load_unaligned_zeropad().

Fix the issue.

v2:
- Add more info in commit message of the first patch.
- Move enc_status_change_finish_noop() into a separate patch.
- Fix typo in commit message and comment.

Kirill A. Shutemov (3):
x86/mm: Allow guest.enc_status_change_prepare() to fail
x86/tdx: Fix race between set_memory_encrypted() and
load_unaligned_zeropad()
x86/mm: Fix enc_status_change_finish_noop()
