Description

In the Linux kernel, the following vulnerability has been resolved: arm64: hibernate: Restore DAIF state on error Sashiko AI has reported that if swsusp_mte_save_tags() for some reason fails we return from swsusp_arch_suspend() with DAIF being masked - that is not what we'd expect. Restore the saved DAIF state before returning from the error path.
