The first two are queued for 6.12. 409f45387c93 ("x86/sev: Fix broken SNP support with KVM module built-in") does not apply there. 6.12 predates the segmented-RMP rework, so snp_rmptable_init() still uses probed_rmp_base/memremap() and the commit needs seven prerequisites, six of them the v6.14-rc1 segmented-RMP/RMPREAD series. That is hardware enablement, not stable material, so I don't want to pull it in as a dependency. Could someone send a tested 6.12.y-specific backport of 409f45387c93? I'll hold 6.12 until it shows up. -- Thanks, Sasha
