[git pull] common helper for kmap_local_page() users in local filesystems

[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.

	The helper is trivial and it's early in the cycle.  It would simplify
the things if you could pull it - then I'd simply rebase the affected branches
to -rc2...
