39aa452031 msm: ipa: Fix to reset the sticky_rear flag
When hotspot tethering is toggled quickly
WLAN_AP_CONNECT is received even before all
the filter rules are cleaned up for the previous
DISCONNECT. As the sticky_rear is set, default
rule is not added at the end. Make a change to
reset sticky_rear when default rules are deleted.

4748cf2bde sched/debug: Make the "Preemption disabled at ..." message more useful
This message is currently really useless since it always prints a value
that comes from the printk() we just did, e.g.:

    BUG: sleeping function called from invalid context at mm/slab.h:388
    in_atomic(): 0, irqs_disabled(): 0, pid: 31996, name: trinity-c1
    Preemption disabled at:[<ffffffff8119db33>] down_trylock+0x13/0x80

    BUG: sleeping function called from invalid context at include/linux/freezer.h:56
    in_atomic(): 0, irqs_disabled(): 0, pid: 31996, name: trinity-c1
    Preemption disabled at:[<ffffffff811aaa37>] console_unlock+0x2f7/0x930

Here, both down_trylock() and console_unlock() is somewhere in the
printk() path.

We should save the value before calling printk() and use the saved value
instead. That immediately reveals the offending callsite:

    BUG: sleeping function called from invalid context at mm/slab.h:388
    in_atomic(): 0, irqs_disabled(): 0, pid: 14971, name: trinity-c2

b3e7113283 msm: kgsl: Remove incorrect check to cap AB vote to IB vote
For dual channel DDR, IB vote from client is half of actual
IB vote as IB vote calculation on client side doesn't consider
number of DDR channels. ICB driver takes care of multiplying
the client IB vote with number of DDR channels.

This change removes the AB capping check to avoid the scenarios
where AB vote > actual IB vote/2 but gets capped to actual
IB vote/2 because client side IB vote is half of actual IB vote.

Removal of this check will not impact single channel DDR targets
because of the way AB value is calculated. In case of honest BW
voting, AB will always be less than IB as AB calculation doesn't
consider RAM wait value. In case of unhonest vote, AB value is
always caluclated as some percentage of IB vote and this percentage
value is always <=100%.

20bc196762 mmc: host: sdhci-msm: Skip reading GENERICS register in check_pwr_status
Skip checking the SWITCHABLE_SIGNALING_VOLTAGE bit of MCI_GENERICS
register while checking power status on SDHC v5.0 onwards.

This bit shows whether controller supports switching of IO signaling
voltage or not.  On SDHC v5.0, switchable signaling voltage support
is present by default and this bit was removed. So we can skip checking
this bit in case of v5.0 controller.

Without this patch, driver tries to read a non-existing bit field which is
causing driver to proceed without waiting for pwr-irq. In some case its
turning off the clock even before pwr irq finishes thus resulting in
un-clocked access errors.

eae2d6033f usb: gadget: mtp: reset string descriptor's index with unbind
When USB host is re-enumerating USB MTP device multiple time, it
has been observed that USB MTP enumeration fails. USB MTP host
side environment (i.e. libmtp) is looking for USB MTP device to
pass string descriptor as "MTP" for successful enumeration. Due
to iInterface ID conflict, USB device is passing next interface
related string descriptor instead of USB MTP interface related
string descriptor. This results into no enumeration with USB MTP
configuration. Fix this issue by resetting mtp_string_defs string
descriptor id to zero, so next mtp_function_bind() call re-allocates
string ID.

and we get an power on event. This will allow the driver to make
progress, for example, to send the test responses and requested

03a5bcaa7e net: ipv6: Add early demux handler for UDP unicast
While running a single stream UDPv6 test, we observed that amount
of CPU spent in NET_RX softirq was much greater than UDPv4 for an
equivalent receive rate. The test here was run on an ARM64 based
Android system. On further analysis with perf, we found that UDPv6
was spending significant time in the statistics netfilter targets
which did socket lookup per packet. These statistics rules perform
a lookup when there is no socket associated with the skb. Since
there are multiple instances of these rules based on UID, there
will be equal number of lookups per skb.

By introducing early demux for UDPv6, we avoid the redundant lookups.
This also helped to improve the performance (800Mbps -> 870Mbps) on a
CPU limited system in a single stream UDPv6 receive test with 1450
byte sized datagrams using iperf.

a65466fee1 drm/msm: Add performance counter tracking
Adreno GPUs have a certain number of fixed performance counters
most of which can be programmed to a large number of different
items (countables). A centralized database in the kernel is
needed to make the most efficient use of counters across processes.

Add performance counter tracking and APIs to allow applications to
reserve performance counters by requesting a group ID and a countable
(countables differ from block to block). The kernel will check to
see if an active counter is already selected for that countable or
if a new one should be assigned. Different processes can share the
same counter if they both need the same countable.

Counters are reserved with DRM_IOCTL_MSM_COUNTER_GET which returns
a counter ID for the reserved counter and the hi/lo offset of
the counter register. The reserving application can either read the
counter from within a PM4 stream or it can use the group ID and
counter ID and read the value of the counter with
DRM_MSM_COUNTER_READ. After the counter is no longer needed
DRM_IOCTL_MSM_COUNTER_PUT returns it and it can be released for
other countables if no other processes are sharing it.

Reservations are tracked for each process and cleaned up if the
process dies without putting back the counters.

bbdda72e6d icnss: Separate debug and verbose log
Right now all the logs are dumped to IPC log buffer but there
are some logs which are logged most often and they overwrite log
buffer where in important logs required for debugging may be
lost. Create debug and verbose log level such that logs which are
logged most often and not as important as debug logs are moved to
verbose log level.

95f2d746fd soc: qcom: glink_ssr: Add kref for cb_data
The variable cb_data is accessed from parallel threads where one thread
can free it anytime, this creates use after free scenerio.

To avoid use after free cases cb_data is freed only when kref count
goes to zero.

898a25d9ad diag: Fix race condition while accessing mdlog session info
This fix allows to avoid possible race condition while
accessing mdlog session info. Without this check there
is a possibility of poison overwritten occurrence.
Also this fix allows mdlog client to check the validity
of process descriptor. Without this fix there is
possibility of crash.

34a8e148af qcom: fg-memif: add support for using IMA single mode
Currently, based on the number of bytes read/written, IMA is
configured for single or burst mode. Add an option to override
to single mode whenever required.

While at it, change pr_err() statements to print some more debug
information which might be useful.
