The value returned by sys_personality has type "long int".
It is saved to a variable of type "int", which is not a problem
yet because the type of task_struct->pesonality is "unsigned int".
The problem is the sign extension from "int" to "long int"
that happens on return from sys_sparc64_personality.
For example, a userspace call personality((unsigned) -EINVAL) will
result to any subsequent personality call, including absolutely
harmless read-only personality(0xffffffff) call, failing with
errno set to EINVAL.

ALSA timer ioctls have an open race and this may lead to a
use-after-free of timer instance object. A simplistic fix is to make
each ioctl exclusive. We have already tread_sem for controlling the
tread, and extend this as a global mutex to be applied to each ioctl.
The downside is, of course, the worse concurrency. But these ioctls
aren't to be parallel accessible, in anyway, so it should be fine to
serialize there.

As struct mci_dma_data is now only used by AVR32, it is nothing but
pointless indirection. Replace it with struct dw_dma_slave in the
AVR32 platform code and with a void pointer elsewhere.

Commit ecb89f2f5f3e7 ("mmc: atmel-mci: remove compat for non DT board

using DT. This restores a fallback mechanism for such cases.

Non-bufferable MMPDUs are sent out to STAs even while in PS mode
(for example probe responses). Applying filtered frame handling for
these doesn't seem to make much sense and will only create more
air utilization when the STA wakes up. Hence, apply filtered frame
handling only for bufferable MMPDUs.
Discovered while testing an old VOIP phone that started probing
for APs while in PS mode. The mac80211/ath9k AP where the STA is
associated would reply with a probe response but the phone sometimes
moved to a new channel already and couldn't ack the probe response
anymore. In that case mac80211 applied filtered frame handling
for the un-acked probe response.

On hw restart, mac80211 might try to reconfigure already
stopped sched scan, if ieee80211_sched_scan_stopped_work()
wasn't scheduled yet.
This in turn will keep the device driver with scheduled scan
configured, while both mac80211 and cfg80211 will clear
their sched scan state once the work is scheduled.
Fix it by ignoring ieee80211_sched_scan_stopped() calls
while in hw restart, and flush the work before starting
the reconfiguration.

My commit below broken PS-Poll handling. In case the driver
has no frames buffered, driver_release_tids will be 0, but
calling find_highest_prio_tid() with 0 as a parameter is
not a good idea:
fls(0) - 1 = -1.
This bug caused mac80211 to think that frames were buffered
in the driver which in turn was confused because mac80211
was asking to release frames that were not reported to
exist.
On iwlwifi, this led to the WARNING below:

This reverts commit cd37a90b2a417e5882414e19954eeed174aa4d29.
Different userspace programs interpreted HWSIM_ATTR_ADDR_TRANSMITTER
and HWSIM_ATTR_ADDR_RECEIVER differently: some expected it to
be an unchanging hardware address that is tied to the radio despite
which address is configured on the interface, while others expected
to be a copy of the address in the frame (the configured address).
The intent of the original authors is unclear.
The latter interpretation doesn't really work properly with multiple
vifs and broadcast frames. Also, as the TA is already in the
frame, userspace programs can actually support configured addresses
in the former interpretation by mapping between them and the supplied
HWSIM_ATTR_ADDR_TRANSMITTER.
So, in the interest of API stability, revert to the previous mode
of operation and going forward use the former interpretation.

On reconfig, in case of sched_scan_req->n_scan_plans > 1,
local->sched_scan_req was never cleared, although
cfg80211_sched_scan_stopped_rtnl() was called, resulting
in local->sched_scan_req holding a stale and preventing
further scheduled scan requests.
Clear it explicitly in this case.

The rule definitions here aren't really valid, they would
be rejected if it came from userspace due to the bandwidth
specified being bigger than the rule's width.
This is fairly much inconsequential since the other rules
around them do enable the bandwidth, but express that better
using the NL80211_RRF_AUTO_BW flag.

Ilan's previous commit 1b894521e60c ("mac80211: handle HW
ROC expired properly") neglected to take into account that
hw_begun was now always set in the software implementation
as well as the offloaded case.
Fix hw_begun to only apply to the offloaded case to make
the check in Ilan's commit safe and correct.

The current (new) code recalculates the new work timeout
for software remain-on-channel whenever any item started.
In two of the callers of ieee80211_handle_roc_started(),
this is completely pointless since they're for hardware
and will skip the recalculation entirely; it's necessary
only in the case of having just added a new item to the
list, as in the last remaining case the recalculation had
just been done.
This last case, however, is also problematic - if one of
the items on the list actually expires during the recalc
the list iteration outside becomes corrupted and crashes.
Fix this by moving the recalculation to the only place
where it's required.

Originally we calculated ht_nodeid as "ht_nodeid = apicid -
boot_cpu_id;" so presumably it could be negative.
But after commit:
01aaea1afbcd ('x86: introduce initial apicid')
we use c->initial_apicid which is an unsigned short and thus always >= 0.
It causes a static checker warning to test for impossible
conditions so let's remove it.

The mfd/s2mpa01.txt duplicates some of the information about bindings
with old mfd/s2mps11.txt. Now common part exists entirely in
mfd/samsung,sec-core.txt so:
- add company prefix to file name (regulator/samsung,s2mpa01.txt),
- remove duplicated information,
- reorganize the contents to match style of
regulator/samsung,s2mps11.txt.

Bindings for Samsung S2M and S5M family PMICs are in mess. They are
spread over different files and subdirectories in a non-consistent way.
The devices and respective drivers for them share a lot in common so
everything could be organized in a more readable way.
Reorganize the S2MPS11/13/14/15 Device Tree bindings to match the
drivers for this family of devices:
- move mfd/s2mps11.txt to mfd/samsung,sec-core.txt for the main MFD
driver (common for entire family),
- split clock block to clock/samsung,s2mps11.txt,
- split regulator block to regulator/samsung,s2mps11.txt.

As we want gpio_chip .get() calls to be able to return negative
error codes and propagate to drivers, we need to go over all
drivers and make sure their return values are clamped to [0,1].
We do this by using the ret = !!(val) design pattern.

This also start to propagate the negative error code from the
smbus call if there is one, as the last commit of this series
will make the gpiolib core deal with that properly.

Pull xfs updates from Dave Chinner:
"There's not a lot in this - the main addition is the CRC validation of
the entire region of the log that the will be recovered, along with
several log recovery fixes. Most of the rest is small bug fixes and
cleanups.
I have three bug fixes still pending, all that address recently fixed
regressions that I will send to next week after they've had some time
in for-next.
Summary:
- extensive CRC validation during log recovery
- several log recovery bug fixes
- Various DAX support fixes
- AGFL size calculation fix
- various cleanups in preparation for new functionality
- project quota ENOSPC notification via netlink
- tracing and debug improvements"

Pull first round of SCSI updates from James Bottomley:
"This includes driver updates from the usual suspects (bfa, arcmsr,
scsi_dh_alua, lpfc, storvsc, cxlflash).
The major change is the addition of the hisi_sas driver, which is an
ARM platform device for SAS. The other change of note is an enormous
style transformation to the atp870u driver (which is our worst written
SCSI driver)"
