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
