636174219b ipv4: do not cache looped multicasts
Starting from 3.6 we cache output routes for
multicasts only when using route to 224/4. For local receivers
we can set RTCF_LOCAL flag depending on the membership but
in such case we use maddr and saddr which are not caching
keys as before. Additionally, we can not use same place to
cache routes that differ in RTCF_LOCAL flag value.

	Fix it by caching only RTCF_MULTICAST entries
without RTCF_LOCAL (send-only, no loopback). As a side effect,
we avoid unneeded lookup for fnhe when not caching because
multicasts are not redirected and they do not learn PMTU.

	Thanks to Maxime Bizon for showing the caching
problems in __mkroute_output for 3.6 kernels: different
RTCF_LOCAL flag in cache can lead to wrong ip_mc_output or
ip_output call and the visible problem is that traffic can
not reach local receivers via loopback.

884162df2a md/raid10: decrement correct pending counter when writing to replacement.
When a write to a replacement device completes, we carefully
and correctly found the rdev that the write actually went to
and the blithely called rdev_dec_pending on the primary rdev,
even if this write was to the replacement.

This means that any writes to an array while a replacement
was ongoing would cause the nr_pending count for the primary
device to go negative, so it could never be removed.

This bug has been present since replacement was introduced in
3.3, so it is suitable for any -stable kernel since then.

e7c0c3fa29 md/raid10: close race that lose writes lost when replacement completes.
When a replacement operation completes there is a small window
when the original device is marked 'faulty' and the replacement
still looks like a replacement.  The faulty should be removed and
the replacement moved in place very quickly, bit it isn't instant.

So the code write out to the array must handle the possibility that
the only working device for some slot in the replacement - but it
doesn't.  If the primary device is faulty it just gives up.  This
can lead to corruption.

So make the code more robust: if either  the primary or the
replacement is present and working, write to them.  Only when
neither are present do we give up.

This bug has been present since replacement was introduced in
3.3, so it is suitable for any -stable kernel since then.

c567b0584c ARM: OMAP2+: omap_device: Correct resource handling for DT boot
When booting with DT the OF core can fill up the resources provided within
the DT blob.
The current way of handling the DT boot prevents us from removing hwmod data
for platforms only suppose to boot with DT (OMAP5 for example) since we need
to keep the whole hwmod database intact in order to have more resources in
hwmod than in DT (to be able to append the DMA resource from hwmod).

To fix this issue we just examine the OF provided resources:
If we do not have resources we use hwmod to fill them.
If we have resources we check if we already able to recive DMA resource, if
no we only append the DMA resurce from hwmod to the OF provided ones.

In this way we can start removing hwmod data for devices which have their
resources correctly configured in DT without regressions.

ef6c5be658 fix incorrect NR_FREE_PAGES accounting (appears like memory leak)
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 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

ca64cae960 md/raid5: Make sure we clear R5_Discard when discard is finished.
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.

ef5b7c69b7 md/raid5: move resolving of reconstruct_state earlier in
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.

It has been a while since dove_defconfig was updated to recent development.
This patch adds all currently available Dove boards, including a DT-enabled
machine.

DT support requires to allow ATAGS passed by boot loader as most of them are
not yet capable of passing DT blobs. Also OF_SERIAL is enabled to actually
see the bootlog.

Finally, sdhci driver for Dove, mv_cesa, GPIO LEDs, and highmem support is
added.

0a0d628573 ARM - OMAP: ads7846: fix pendown debounce setting
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.

Correct. I did the conversion and tested that the partitions
can be read with dd and produce exactly the same data before and
after conversion. So, the partition offsets at least should be fine.

Ok, I did convert the i2c definition to use the devicetree.
The adt7476 device itself is not at reach of device tree,
AFAIK and requires more work at there?

Thanks for your valuable comments. Following is a new patch that
should address the problems and mistakes you pointed and also
some of the pointed by Jason Cooper. The nand and i2c are now
defined at DT and I also removed the pointless defines and
ARM_APPENDED_DTB. It is based against the Linus' official
3.6 version.

- A GPIO fan which is only available on the NS2 Mini.
- A single USB host port is wired on the NS2 Mini. The NS2 Lite provides
  an additional dual-mode USB port (host/device).

- CPU: Marvell 88F6192 800Mhz
- SDRAM memory: 128MB DDR2 200Mhz
- 1 SATA port: internal
- Gigabit ethernet: PHY Marvell 88E1318
- Flash memory: SPI NOR 512KB (Macronix MX25L4005A)
- i2c EEPROM: 512 bytes (24C04 type)
- 2 USB2 ports: host and host/device
- 1 push button
- 1 SATA LED (bi-color, blue and red)

Note that the SATA LED is not compatible with the driver leds-ns2. The
LED behaviour ("on", "off" or "SATA activity blink") is controlled via
a single MPP (21).
