[patch 05/24] mm: page_vma_mapped_walk(): crossing page table boundary

by Andrew Morton

From: Hugh Dickins <hughd(a)google.com> Subject: mm: page_vma_mapped_walk(): crossing page table boundary page_vma_mapped_walk() cleanup: adjust the test for crossing page table boundary - I believe pvmw->address is always page-aligned, but nothing else here assumed that; and remember to reset pvmw->pte to NULL after unmapping the page table, though I never saw any bug from that.

[patch 04/24] mm: page_vma_mapped_walk(): prettify PVMW_MIGRATION block

I've marked all of these for stable: many are merely cleanups, but I think they are much better before the main fix than after. This patch (of 11): page_vma_mapped_walk() cleanup: sometimes the local copy of pvwm->page was used, sometimes pvmw->page itself: use the local copy "page" throughout.

[PATCH 5.12 v2] KVM: SVM: Call SEV Guest Decommission if ASID binding fails

by Alper Gun

commit 934002cd660b035b926438244b4294e647507e13 upstream. Send SEV_CMD_DECOMMISSION command to PSP firmware if ASID binding fails. If a failure happens after a successful LAUNCH_START command, a decommission command should be executed. Otherwise, guest context will be unfreed inside the AMD SP. After the firmware will not have memory to allocate more SEV guest context, LAUNCH_START command will begin to fail with SEV_RET_RESOURCE_LIMIT error. The existing code calls decommission inside sev_unbind_asid, but it is not called if a failure happens before guest activation succeeds. If sev_bind_asid fails, decommission is never called. PSP firmware has a limit for the number of guests. If sev_asid_binding fails many times, PSP firmware will not have resources to create another guest context.
