Its filename is > mm-truncateshmem-handle-truncates-that-split-thps-fix-fix.patch Andrew, Stephen, This lot is proving to be a work in progress, the current state breaks booting on 32-bit, livelocks trinity, and breaks shmem in more ways than I can quickly explain. Please revert (in reverse order): mm-truncateshmem-handle-truncates-that-split-thps.patch mm-truncateshmem-handle-truncates-that-split-thps-fix.patch mm-truncateshmem-handle-truncates-that-split-thps-fix-fix.patch mm-filemap-return-only-head-pages-from-find_get_entries.patch (I don't think there's any problem with that last patch, but assume that it relies on ..split-thpfs.patch being in already.) Thanks, Hugh
