This has been in mm-unstable for a long time. As the series had a mixture of cc:stable and not-cc:stable patches, I figured we'd merge them all into next merge window and let the -stable maintainers figure it all out. As this is more urgent than I believed, we need to figure out what to do. a) Pluck out the two cc:stable patches, merge just those into 6.19-rc. b) Merge all of them into 6.19-rc, let -stable maintainers figure it out c) Stick with my original plan. The cc:stable "mm/hugetlb: fix excessive IPI broadcasts when unsharing PMD tables using mmu_gather" has dependencies on the preceding two non-cc:stable patches. So I'm thinking I add cc:stable to everything and send the whole series into 6.19-rcX. wdyt? Also, David, where do we stand with : I'd love to get some generic hugetlb testing on arm64 and powerpc, : that do hugetlb TLB flushing stuff a bit more special. : : I'll try doing some arm64 testing early in the new year myself. ?
