[PATCH v2 0/8] Misc MM patches

[Matthew Wilcox <willy@infradead.org>]

From: "Matthew Wilcox (Oracle)" <willy@infradead.org>

These are all things that I noticed while working on the THP patches, but
all stand alone as useful MM cleanups.  Andrew, please consider applying.

There's two extra patches in here compared to v1; I separated out the
patch renaming the arguments to find_subpage() from the patch converting
it to use hpage_nr_pages(), and I added a patch to check PageTail()
in hpage_nr_pages() for the !THP case.

Patch 5 (Remove CONFIG_TRANSPARENT_HUGE_PAGECACHE) adds the missing hunk
that Alex Duyck pointed out.

Patch 8 (pagecache_get_page documentation) also renames the 'offset'
parameter to 'index'.
