There have been some 3.7-rc reports of vm issues, including some kswapd
bugs and, more importantly, some memory "leaks":

	http://www.spinics.net/lists/linux-mm/msg46187.html
	https://bugzilla.kernel.org/show_bug.cgi?id=50181

Commit 1fb3f8ca ("mm: compaction: capture a suitable high-order page
immediately when it is made available") took split_free_page() and
reused it for the compaction code.  It does something curious with
capture_free_page() (previously known as split_free_page()):

  int capture_free_page(struct page *page, int alloc_order,
  ...
          __mod_zone_page_state(zone, NR_FREE_PAGES, -(1UL << order));

  -       /* Split into individual pages */
  -       set_page_refcounted(page);
  -       split_page(page, order);
  +       if (alloc_order != order)
  +               expand(zone, page, alloc_order, order,
  +                       &zone->free_area[order], migratetype);

Note that expand() puts the pages _back_ in the allocator, but it does
not bump NR_FREE_PAGES.  We "return" 'alloc_order' worth of pages, but
we accounted for removing 'order' in the __mod_zone_page_state() call.

For the old split_page()-style use (order==alloc_order) the bug will not
trigger.  But, when called from the compaction code where we
occasionally get a larger page out of the buddy allocator than we need,
we will run in to this.

This patch simply changes the NR_FREE_PAGES manipulation to the correct
'alloc_order' instead of 'order'.

I've been able to repeatedly trigger this in my testing environment.
The amount "leaked" very closely tracks the imbalance I see in buddy
pages vs.  NR_FREE_PAGES.  I have confirmed that this patch fixes the
imbalance

Merge tag 'omap-for-v3.7-rc5/fixes-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes

From Tony Lindgren:
Few more regression fixes related to u-boot only muxing

  ARM: OMAP3: igep0020: Set WIFI/BT GPIO pins in correct mux mode
  ARM: OMAP: Add maintainer entry for IGEP machines

Commit 97ee9f01 (ARM: OMAP: fix the ads7846 init code) have enabled the
pendown GPIO debounce time setting by the below sequence:

  gpio_request_one()
  gpio_set_debounce()
  gpio_free()

It also revealed a bug in the OMAP GPIO handling code which prevented
the GPIO debounce clock to be disabled and CORE transition to low power
states.

Commit c9c55d92 (gpio/omap: fix off-mode bug: clear debounce settings on
free/reset) fixes the OMAP GPIO handling code by making sure that the
GPIO debounce clock gets disabled if no GPIO is requested from current
bank.

While fixing the OMAP GPIO handling code (in the right way), the above
commit makes the gpio_request->set_debounce->free sequence invalid as
after freeing the GPIO, the debounce settings are lost.

Fix the debounce settings by moving the debounce initialization to the
actual GPIO requesting code - the ads7846 driver.

"Please also pull my iwlwifi.git tree, I have two fixes: one to remove a
spurious warning that can actually trigger in legitimate situations, and
the other to fix a regression from when monitor mode was changed to use
the "sniffer" firmware mode."

Also included is an nfc tree pull.  Samuel says:

"We mostly have pn533 fixes here, 2 memory leaks and an early unlocking fix.
Moreover, we also have an LLCP adapter linked list insertion fix."

to rtlwifi.  Bing Zhao provides two mwifiex fixes -- one to fix
a system hang during a command timeout, and the other to properly
report a suspend error to the MMC core.  Finally, Sujith Manoharan

This is a regression introduced by ceb90fa0 (xen/privcmd: add
PRIVCMD_MMAPBATCH_V2 ioctl).  It broke xentrace as it used
xc_map_foreign() instead of xc_map_foreign_bulk().

Most code-paths prefer the MMAPBATCH_V2, so this wasn't very obvious
that it broke. The return value is set early on to -EINVAL, and if all
goes well, the "set top bits of the MFN's" never gets called, so the
return value is still EINVAL when the function gets to the end, causing
the caller to think it went wrong (which it didn't!)
