They fix simple and more severe issues and are all targeted for v5.13. The most important fixes are the revert of 7024f60d6552 which just doesn't work in any context the #VC handler could run and the fix to forward #PF exceptions caused during emulation. The issue that 7024f60d6552 intended to fix should be fixed correctly with these patches too. Please review and test. Regards, Joerg Joerg Roedel (6): x86/sev-es: Don't return NULL from sev_es_get_ghcb() x86/sev-es: Forward page-faults which happen during emulation x86/sev-es: Use __put_user()/__get_user Revert "x86/sev-es: Handle string port IO to kernel memory properly" x86/sev-es: Fix error message in runtime #VC handler x86/sev-es: Leave NMI-mode before sending signals arch/x86/kernel/sev.c | 76 +++++++++++++++++++++---------------------- 1 file changed, 38 insertions(+), 38 deletions(-) base-commit: 059e5c321a65657877924256ea8ad9c0df257b45 -- 2.31.1
