Merge tag 'pull-highmem' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs

Pull put_and_unmap_page() helper from Al Viro:
"kmap_local_page() conversions in local filesystems keep running into
kunmap_local_page()+put_page() combinations. We can keep inventing
names for identical inline helpers, but it's getting rather
inconvenient. I've added a trivial helper to linux/highmem.h instead.

I would've held that back until the merge window, if not for the mess
it causes in tree topology - I've several branches merging from that
one, and it's only going to get worse if e.g. ext2 stuff gets picked
by Jan"
