Queued the first two for 6.12 - they go in as a unit, since the second is the only caller of the helper the first adds, and the tree would not link with just one. The third is a separable pre-existing fix rather than a prerequisite: the RMP-init ordering has been wrong on 6.12 for CONFIG_KVM_AMD=y since the SNP host support landed, independent of either backport, and it conflicts on this tree. Backports are welcome :) -- Thanks, Sasha
