From Simon Horman:
Second Round of Renesas ARM based SoC Fixes for v3.13
* r8a7790 (R-Car H2) based Lager board
- Correct SHDI resource sizes
This bug has been present since sdhi resources were added to the r8a7790 by
8c9b1aa41853272a ("ARM: shmobile: r8a7790: add MMCIF and SDHI DT
templates") in v3.11-rc2.
* r8a7778 (R-Car M1) based Bock-W board
- Correct DMA mask
This resolves a regression introduced by 4dcfa60071b3d23f
("ARM: DMA-API: better handing of DMA masks for coherent allocations")
in v3.12-rc1.
* r8a7740 (R-Mobile A1) based Armadillo board
- Add PWM backlight power supply
This resolves a regression introduced by 22ceeee16eb8f0d0
("pwm-backlight: Add power supply support") in v3.12.

After commit 88f718e3fa4d67f3a8dbe79a2f97d722323e4051
"ARM: pxa: delete the custom GPIO header" a compilation
error was introduced in the PXA25x gadget driver.
An attempt to fix the problem was made in
commit b144e4ab1ef130e8bf30bcd3e529b7f35112c503
"usb: gadget: fix pxa25x compilation problems"
by explictly stating the driver needs the <mach/hardware.h>
header, which solved the compilation for a few boards,
such as the pxa255-idp and its defconfig.
However the Lubbock board has this special clause in
drivers/usb/gadget/pxa25x_udc.c:
This include file has an implicit dependency on
<mach/irqs.h> having been included before <mach/lubbock.h>
was included.
Before commit 88f718e3fa4d67f3a8dbe79a2f97d722323e4051
"ARM: pxa: delete the custom GPIO header" this implicit
dependency for the pxa25x_udc compile on the Lubbock was
satisfied by <linux/gpio.h> implicitly including
<mach/gpio.h> which was in turn including <mach/irqs.h>,
apart from the earlier added <mach/hardware.h>.
Fix this by having the PXA25x <mach/lubbock.h> explicitly
include <mach/irqs.h>.

I accidentally removed some mux code for omap4 that I thought was

The r8a7790.dtsi file has four sdhi nodes which the first two have the wrong
resource size for their register block. This causes the sh_modbile_sdhi driver
to fail to communicate with card at-all.
Change sdhi{0,1} node size from 0x100 to 0x200 to correct these nodes
as per Kuninori Morimoto's response to the original patch where all four
nodes where changed. sdhi{2,3} are the correct size.
This bug has been present since sdhi resources were added to the r8a7790 by
8c9b1aa41853272a ("ARM: shmobile: r8a7790: add MMCIF and SDHI DT
templates") in v3.11-rc2.

For NUMA systems, initializing the blk-mq layer and using per node hctx.
We initialize submit queues to 1, while blk-mq nr_hw_queues is
initialized to the number of NUMA nodes.
This makes the null_init_hctx function overwrite memory outside of what
it allocated. In my case it lead to writing garbage into struct
request_queue's mq_map.

radeon_hwmon_show_temp_thresh()
Since commit ec39f64bba34 ("drm/radeon/dpm: Convert to use
devm_hwmon_register_with_groups") radeon_hwmon_init() is using
hwmon_device_register_with_groups(), which sets `rdev' as a device
private driver_data, while hwmon_attributes_visible() and
radeon_hwmon_show_temp_thresh() are still waiting for `drm_device'.
Fix them by using dev_get_drvdata(), in order to avoid this oops:

Pull networking fixes from David Miller:
1) Revert CHECKSUM_COMPLETE optimization in pskb_trim_rcsum(), I can't
figure out why it breaks things.
2) Fix comparison in netfilter ipset's hash_netnet4_data_equal(), it
was basically doing "x == x", from Dave Jones.
3) Freescale FEC driver was DMA mapping the wrong number of bytes, from
Sebastian Siewior.
4) Blackhole and prohibit routes in ipv6 were not doing the right thing
because their ->input and ->output methods were not being assigned
correctly. Now they behave properly like their ipv4 counterparts.
From Kamala R.
5) Several drivers advertise the NETIF_F_FRAGLIST capability, but
really do not support this feature and will send garbage packets if
fed fraglist SKBs. From Eric Dumazet.
6) Fix long standing user triggerable BUG_ON over loopback in RDS
protocol stack, from Venkat Venkatsubra.
7) Several not so common code paths can potentially try to invoke
packet scheduler actions that might be NULL without checking. Shore
things up by either 1) defining a method as mandatory and erroring
on registration if that method is NULL 2) defininig a method as
optional and the registration function hooks up a default
implementation when NULL is seen. From Jamal Hadi Salim.
8) Fix fragment detection in xen-natback driver, from Paul Durrant.
9) Kill dangling enter_memory_pressure method in cg_proto ops, from
Eric W Biederman.
10) SKBs that traverse namespaces should have their local_df cleared,
from Hannes Frederic Sowa.
11) IOCB file position is not being updated by macvtap_aio_read() and
tun_chr_aio_read(). From Zhi Yong Wu.
12) Don't free virtio_net netdev before releasing all of the NAPI
instances. From Andrey Vagin.
13) Procfs entry leak in xt_hashlimit, from Sergey Popovich.
14) IPv6 routes that are no cached routes should not count against the
garbage collection limits. We had this almost right, but were
missing handling addrconf generated routes properly. From Hannes
Frederic Sowa.
15) fib{4,6}_rule_suppress() have to consider potentially seeing NULL
route info when they are called, from Stefan Tomanek.
16) TUN and MACVTAP have had truncated packet signalling for some time,
fix from Jason Wang.
17) Fix use after frrr in __udp4_lib_rcv(), from Eric Dumazet.
18) xen-netback does not interpret the NAPI budget properly for TX work,
fix from Paul Durrant.

This reverts commit 102aefdda4d8275ce7d7100bc16c88c74272b260.
Tom London reports that it causes sync() to hang on Fedora rawhide:
https://bugzilla.redhat.com/show_bug.cgi?id=1033965
and Josh Boyer bisected it down to this commit. Reverting the commit in
the rawhide kernel fixes the problem.
Eric Paris root-caused it to incorrect subtype matching in that commit
breaking fuse, and has a tentative patch, but by now we're better off
retrying this in 3.14 rather than playing with it any more.

4178bac ARM: call of_clk_init from default time_init handler
added implicit call to of_clk_init() from default time_init callback,
but it did not change platforms calling it from other callbacks, despite
of not having custom time_init callbacks. This caused double clock
initialization on such platforms, leading to boot failures. An example
of such platform is mach-s3c64xx.
This patch fixes boot failure on s3c64xx by dropping custom init_irq
callback, which had a call to of_clk_init() and moving system reset
initialization to init_machine callback. This allows us to have
clocks initialized properly without a need to have custom init_time or
init_irq callbacks.

An old array block could have its reference count decremented below
zero when it is being replaced in the btree by a new array block.
The fix is to increment the old ablock's reference count just before
inserting a new ablock into the btree.

The old behaviour, returning -EINVAL if a ref_count of 0 would be
decremented, was removed in commit f722063 ("dm space map: optimise
sm_ll_dec and sm_ll_inc"). To fix this regression we return an error
code from the mutator function pointer passed to sm_ll_mutate() and have
dec_ref_count() return -EINVAL if the old ref_count is 0.
Add a DMERR to reflect the potential seriousness of this error.
Also, add missing dm_tm_unlock() to sm_ll_mutate()'s error path.
With this fix the following dmts regression test now passes:
dmtest run --suite cache -n /metadata_use_kernel/
The next patch fixes the higher-level dm-array code that exposed this
regression.

Commit 4942642080ea ("mm: memcg: handle non-error OOM situations more
gracefully") allowed tasks that already entered a memcg OOM condition to
bypass the memcg limit on subsequent allocation attempts hoping this
would expedite finishing the page fault and executing the kill.
David Rientjes is worried that this breaks memcg isolation guarantees
and since there is no evidence that the bypass actually speeds up fault
processing just change it so that these subsequent charge attempts fail
outright. The notable exception being __GFP_NOFAIL charges which are
required to bypass the limit regardless.

There is a race condition between a memcg being torn down and a swapin
triggered from a different memcg of a page that was recorded to belong
to the exiting memcg on swapout (with CONFIG_MEMCG_SWAP extension). The
result is unreclaimable pages pointing to dead memcgs, which can lead to
anything from endless loops in later memcg teardown (the page is charged
to all hierarchical parents but is not on any LRU list) or crashes from
following the dangling memcg pointer.
Memcgs with tasks in them can not be torn down and usually charges don't
show up in memcgs without tasks. Swapin with the CONFIG_MEMCG_SWAP
extension is the notable exception because it charges the cgroup that
was recorded as owner during swapout, which may be empty and in the
process of being torn down when a task in another memcg triggers the
swapin:
teardown: swapin:
lookup_swap_cgroup_id()
rcu_read_lock()
mem_cgroup_lookup()
css_tryget()
rcu_read_unlock()
disable css_tryget()
call_rcu()
offline_css()
reparent_charges()
res_counter_charge() (hierarchical!)
css_put()
css_free()
pc->mem_cgroup = dead memcg
add page to dead lru
Add a final reparenting step into css_free() to make sure any such raced
charges are moved out of the memcg before it's finally freed.
In the longer term it would be cleaner to have the css_tryget() and the
res_counter charge under the same RCU lock section so that the charge
reparenting is deferred until the last charge whose tryget succeeded is
visible. But this will require more invasive changes that will be
harder to evaluate and backport into stable, so better defer them to a
separate change set.

Rename old regmap field of "struct sec_pmic_dev" to "regmap_pmic" and
add new regmap for RTC.
On S5M8767A registers were not properly updated and read due to usage of
the same regmap as the PMIC. This could be observed in various hangs,
e.g. in infinite loop during waiting for UDR field change.
On this chip family the RTC has different I2C address than PMIC so
additional regmap is needed.

Commit fad1a86e25e0 ("procfs: call default get_unmapped_area on
MMU-present architectures"), as its title says, took care of only the
MMU case, leaving the !MMU side still in the regressed state (returning
-EIO in all cases where pde->proc_fops->get_unmapped_area is NULL).
From the fad1a86e25e0 changelog:
"Commit c4fe24485729 ("sparc: fix PCI device proc file mmap(2)") added
proc_reg_get_unmapped_area in proc_reg_file_ops and
proc_reg_file_ops_no_compat, by which now mmap always returns EIO if
get_unmapped_area method is not defined for the target procfs file, which
causes regression of mmap on /proc/vmcore.
To address this issue, like get_unmapped_area(), call default
current->mm->get_unmapped_area on MMU-present architectures if
pde->proc_fops->get_unmapped_area, i.e. the one in actual file operation
in the procfs file, is not defined"

Commit 84235de394d9 ("fs: buffer: move allocation failure loop into the
allocator") started recognizing __GFP_NOFAIL in memory cgroups but
forgot to disable the OOM killer.
Any task that does not fail allocation will also not enter the OOM
completion path. So don't declare an OOM state in this case or it'll be
leaked and the task be able to bypass the limit until the next
userspace-triggered page fault cleans up the OOM state.
