Some more misc fallout from nouveau rework.
* 'drm-nouveau-fixes' of git://anongit.freedesktop.org/git/nouveau/linux-2.6:
drm/nouveau/bios: fix DCB v1.5 parsing
drm/nouveau: add missing pll_calc calls
drm/nouveau: fix crash with noaccel=1
drm/nv40: allocate ctxprog with kmalloc
drm/nvc0/disp: fix thinko in vblank regression fix..
Only compile time tested, noticed nv50_fence_create was never used,
so fix this. This will probably fix vblank on nv50 cards.
Hopefully this is still in time for 3.7 final release.

And indeed, its used to strcpy to a fixed-sized buffer.

Due to the missing ininitalization at adding/deleting entries, when
a plain_ip,port,net element was the object, multiple elements were
added/deleted instead. The bug came from the missing dangling
default initialization.
The error-prone default initialization is corrected in all hash:* types.

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.htmlhttps://bugzilla.kernel.org/show_bug.cgi?id=50181
Commit 1fb3f8ca0e ("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

Pull networking updates from David Miller:
1) inet6_csk_update_pmtu() must return NULL or non-NULL, so translate
ERR_PTR to NULL, as needed. Fix from Eric Dumazet.
2) Fix copy&paste error in IRDA sir_dev ->set_speed method invocation,
it was testing the NULL'ness of a different method to guard the
call. Fix from Alexander Shiyan.
3) Fix build regression of xilinx driver, from Jeff Mahoney.
4) Make XEN netfront (like XEN netback) handle compound pages in SKBs
properly. From Ian Campbell.
5) Fix inverted logic of team_dev_queue_xmit() return value checks,
from Jiri Pirko and Dan Carpenter.
6) dma_poll_create() no longer allows a NULL device argument, breaking
both ixp4xx drivers. Fix from Xi Wang.
7) ne2000 driver doesn't hook up the parent device properly, breaking
udev matching. Fix from Alan Cox.
8) Locking and memory leak fixes in Near Field Communications layer.
From Thierry Escande, Szymon Janc, and Waldemar Rymarkiewicz.
9) sis900 resume regression, sis900_set_mode() is being called with the
iomem pointer instead of the expected device private. Fix from
Francois Romieu.
10) Fix IBSS regression caused by uninitializing the ibss-internals
before performing an emptyness check, from Simon WUnderlich.
11) Fix SNIFFER mode regression in iwlwifi driver, from Johannes Berg.
12) Fix task wedges in mwifiex_cmd_timeout_func(), from Bing Zhao.
13) Add back wireless sysfs directory, too much stuff depends upon it
being there (actually I'd say it never should have been removed to
begin with). From Johannes Berg.
14) Fix hang introduced by suspend/resume changes in ath9k. Fix from
Sujith Manoharan.

commit 9e44476851
MD: raid5 avoid unnecessary zero page for trim
change raid5 to clear R5_Discard when the complete request is
handled rather than when submitting the per-device discard request.
However it did not clear R5_Discard for the parity device.
This means that if the stripe_head was reused before it expired from
the cache, the setting would be wrong and a hang would result.
Also if the R5_Uptodate bit happens to be set, R5_Discard again
won't be cleared. But R5_Uptodate really should be clear at this point.
So make sure R5_Discard is cleared in all cases, and clear
R5_Uptodate when a 'discard' completes.

stripe_handle.
The chunk of code in stripe_handle which responds to a
*_result value in reconstruct_state is really the completion
of some processing that happened outside of handle_stripe
(possibly asynchronously) and so should be one of the first
things done in handle_stripe().
After the next patch it will be important that it happens before
handle_stripe_clean_event(), as that will clear some dev->flags
bit that this code tests.

From Tony Lindgren:
Few more regression fixes related to u-boot only muxing
essential pins.
* tag 'omap-for-v3.7-rc5/fixes-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
ARM: OMAP4: TWL: mux sys_drm_msecure as output for PMIC
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 c9c55d9 (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.

Since the pendown GPIO is handled by the driver, the debounce time

John W. Linville says:
====================
This is a batch of fixes intended for 3.7...
Included are two pulls. Regarding the mac80211 tree, Johannes says:
"Please pull my mac80211.git tree (see below) to get two more fixes for
3.7. Both fix regressions introduced *before* this cycle that weren't
noticed until now, one for IBSS not cleaning up properly and the other
to add back the "wireless" sysfs directory for Fedora's startup scripts."
Regarding the iwlwifi tree, Johannes says:
"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."
On top of that, a few more bits... Albert Pool adds a USB ID
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
fixes a thinko that would trigger an ath9k hang during device reset.
