Input: mousedev - fix race when creating mixed device
We should not be using static variable mousedev_mix in methods that can be
called before that singleton gets assigned. While at it let's add open and
close methods to mousedev structure so that we do not need to test if we
are dealing with multiplexor or normal device and simply call appropriate
method directly.

Input: don't modify the id of ioctl-provided ff effect on upload failure
If a new (id == -1) ff effect was uploaded from userspace,
ff-core.c::input_ff_upload() will have assigned a positive number to the
new effect id. Currently, evdev.c::evdev_do_ioctl() will save this new id
to userspace, regardless of whether the upload succeeded or not.
On upload failure, this can be confusing because the dev->ff->effects[]
array will not contain an element at the index of that new effect id.
This patch fixes this by leaving the id unchanged after upload fails.
Note: Unfortunately applications should still expect changed effect id for
quite some time.
This has been discussed on:

Input: synaptics - add manual min/max quirk
The new Lenovo Haswell series (-40's) contains a new Synaptics touchpad.
However, these new Synaptics devices report bad axis ranges.
Under Windows, it is not a problem because the Windows driver uses RMI4
over SMBus to talk to the device. Under Linux, we are using the PS/2
fallback interface and it occurs the reported ranges are wrong.
Of course, it would be too easy to have only one range for the whole
series, each touchpad seems to be calibrated in a different way.
We can not use SMBus to get the actual range because I suspect the firmware
will switch into the SMBus mode and stop talking through PS/2 (this is the
case for hybrid HID over I2C / PS/2 Synaptics touchpads).
So as a temporary solution (until RMI4 land into upstream), start a new
list of quirks with the min/max manually set.

Input: cypress_ps2 - don't report as a button pads
The cypress PS/2 trackpad models supported by the cypress_ps2 driver
emulate BTN_RIGHT events in firmware based on the finger position, as part
of this no motion events are sent when the finger is in the button area.
The INPUT_PROP_BUTTONPAD property is there to indicate to userspace that
BTN_RIGHT events should be emulated in userspace, which is not necessary
in this case.
When INPUT_PROP_BUTTONPAD is advertised userspace will wait for a motion
event before propagating the button event higher up the stack, as it needs
current abs x + y data for its BTN_RIGHT emulation. Since in the
cypress_ps2 pads don't report motion events in the button area, this means
that clicks in the button area end up being ignored, so
INPUT_PROP_BUTTONPAD actually causes problems for these touchpads, and
removing it fixes:

null_blk: mem garbage on NUMA systems during init
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.

mm: memcg: do not allow task about to OOM kill to bypass the limit
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.

mm: memcg: fix race condition between memcg teardown and swapin
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 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

"Commit
c4fe24485729 ("sparc: fix PCI device proc file mmap(2)") added
proc_reg_get_unmapped_area in proc_reg_file_ops and

get_unmapped_area method is not defined for the target procfs file, which
causes regression of mmap on /proc/vmcore.

mtd: nand: pxa3xx: Use info->use_dma to release DMA resources

mtd: nand: pxa3xx: Allocate data buffer on detected flash size
the way the buffer is allocated was changed: the first READ_ID is issued
with a small kmalloc'ed buffer. Only once the flash page size is detected
the DMA buffers are allocated, and info->use_dma is set.
Currently, if the device detection fails, the driver checks the 'use_dma'
module parameter and tries to release unallocated DMA resources.
Fix this by checking the proper indicator of the DMA allocation, which
is 'info->use_dma'.

Partially revert "mtd: nand: pxa3xx: Introduce 'marvell,armada370-nand' compatible string"
This partially reverts
c0f3b8643a6fa2461d70760ec49d21d2b031d611.
The "armada370-nand" compatible support is not complete, and it was mistake
to add it. Revert it and postpone the support until the infrastructure is
in place.

selinux: process labeled IPsec TCP SYN-ACK packets properly in selinux_ip_postroute()
Due to difficulty in arriving at the proper security label for
TCP SYN-ACK packets in selinux_ip_postroute(), we need to check packets
while/before they are undergoing XFRM transforms instead of waiting
until afterwards so that we can determine the correct security label.
