Merge tag 'x86_sev_for_v6.6_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 SEV updates from Borislav Petkov: - Handle the case where the beginning virtual address of the address range whose SEV encryption status needs to change, is not page aligned so that callers which round up the number of pages to be decrypted, would mark a trailing page as decrypted and thus cause corruption during live migration. - Return an error from the #VC handler on AMD SEV-* guests when the debug registers swapping is enabled as a DR7 access should not happen then - that register is guest/host switched. * tag 'x86_sev_for_v6.6_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/sev: Make enc_dec_hypercall() accept a size instead of npages x86/sev: Do not handle #VC for DR7 read/write
