My recent change to netvsc drive in how receive flags are handled
broke multicast. The Hyper-v/Azure virtual interface there is not a
multicast filter list, filtering is only all or none. The driver must
enable all multicast if any multicast address is present.

Description:
Crash was reported with syzkaller pointing to lan78xx_write_reg routine.
Root-cause:
Proper cleanup of workqueues and init/setup routines was not happening

In ca8210_test_int_user_write() a user can request the transfer of a
frame with a length field (command.length) that is longer than the
actual buffer provided (len). In this scenario the driver will copy
the buffer contents into the uninitialised command[] buffer, then
transfer <data.length> bytes over the SPI even though only <len> bytes
had been populated, potentially leaking sensitive kernel memory.
Also the first 6 bytes of the command buffer must be initialised in case
a malformed, short packet is written and the uninitialised bytes are
read in ca8210_test_check_upstream.

This is a cosmetic patch that deals with the address filter structure's
ambiguous fields 'filter' and 'range'. The former stands to mean that the
filter's *action* should be to filter the traces to its address range if
it's set or stop tracing if it's unset. This is confusing and hard on the
eyes, so this patch replaces it with 'action' enum. The 'range' field is
completely redundant (meaning that the filter is an address range as
opposed to a single address trigger), as we can use zero size to mean the
same thing.

- There are three PHY lanes on iMX8QM, and can be
used in the following three cases
1. a two lanes PCIE_A, and a single lane SATA.
2. a single lane PCIE_A, a single lane PCIE_B
and a single lane SATA.
3. a two lanes PCIE_A, and a single lane PCIE_B.
The configuration of the iMX8QM AHCI SATA is relied
on the usage of PCIE ports in the case 1 and 2.
Use standalone iMX8 AHCI SATA probe and enable
functions to enable iMX8QM AHCI SATA support.
- To save power consumption, PHY CLKs can be gated
off after the configurations are done.
- The impedance ratio should be configured refer to
differnet REXT values.
0x6c <--> REXT value is 85Ohms
0x80 (default value) <--> REXT value is 100Ohms.
In general, REXT value should be 85ohms in standalone
PCIE HW board design, and 100ohms in SATA standalone
HW board design.
When the PCIE and the SATA are enabled simultaneously
in the HW board design. The REXT value would be set
to 85ohms.
Configure the SATA PHY impedance ratio to 0x6c in
default.

Rik reports that he sees an increase in CPU use in one benchmark
due to commit 612f1a22f067 "cpuidle: poll_state: Add time limit to
poll_idle()" that caused poll_idle() to call local_clock() in every
iteration of the loop. Utilization increase generally means more
non-idle time with respect to total CPU time (on the average) which
implies reduced CPU frequency.
Doug reports that limiting the rate of local_clock() invocations
in there causes much less power to be drawn during a CPU-intensive
parallel workload (with idle states 1 and 2 disabled to enforce more
state 0 residency).
These two reports together suggest that executing local_clock() on
multiple CPUs in parallel at a high rate may cause chips to get hot
and trigger thermal/power limits on them to kick in, so reduce the
rate of local_clock() invocations in poll_idle() to avoid that issue.

Add a new attribute group called "s2idle" under the sysfs directory
of each cpuidle state that supports the ->enter_s2idle callback
and put two new attributes, "usage" and "time", into that group to
represent the number of times the given state was requested for
suspend-to-idle and the total time spent in suspend-to-idle after
requesting that state, respectively.
That will allow diagnostic information related to suspend-to-idle
to be collected without enabling advanced debug features and
analyzing dmesg output.

If poll_idle() is allowed to spin until need_resched() returns 'true',
it may actually spin for a much longer time than expected by the idle
governor, since set_tsk_need_resched() is not always called by the
timer interrupt handler. If that happens, the CPU may spend much
more time than anticipated in the "polling" state.
To prevent that from happening, limit the time of the spinning loop
in poll_idle().

Currently vdev stats displayed in fw_stats are applicable
only for TLV based firmware and fix it for 10.4 firmware
as of now. The vdev stats in 10.4 firmware is split into two
parts (vdev_stats, vdev_stats_extended). The actual stats
are captured only in extended vdev stats. In order to enable
vdev stats, appropriate feature bit will be set on extended
resource config. As FTM related counters are available only on
newer 10.4 based firmware, these counters will be displayed
only on valid data.

In case wcn36xx_smd_rsp_process() is called more than once before
hal_ind_work was dispatched, the messages will end up in hal_ind_queue,
but wcn36xx_ind_smd_work() will only look at the first message in that
list.
Fix this by dequeing the messages from the list in a loop, and only stop
when it's empty.

race never actually occured.

wcn36xx_start_tx function retrieves the buffer descriptor from the
channel control queue to start filling tx buffer information. However,
nothing prevents this same buffer to be concurrently accessed in a
concurent tx call, leading to potential buffer coruption and firmware
crash (observed during iperf test). The channel control queue should
only be accessed and updated with the channel lock.
Fix this issue by using a local buffer descriptor which will be copied
in the thread-safe wcn36xx_dxe_tx_frame.
Note that buffer descriptor size is few bytes so the introduced copy
overhead is insignificant. Moreover, this allows to keep the locked
section minimal.

This reverts commit 55884c045d31a29cf69db8332d1064a1b61dd159.
When Ath10k is in AP mode and an unassociated STA sends a VHT action frame
(Operating Mode Notification for the NSS change) periodically to AP this causes
ath10k to call ath10k_station_assoc() which sends WMI_PEER_ASSOC_CMDID during
NSS update. Over the time (with a certain client it can happen within 15 mins
when there are over 500 of these VHT action frames) continuous calls of
WMI_PEER_ASSOC_CMDID cause firmware to assert due to resource exhaust.
To my knowledge setting WMI_PEER_NSS peer param itself enough to handle NSS
updates and no need to call ath10k_station_assoc(). So revert the original
commit from 2014 as it's unclear why the change was really needed.
Now the firmware assert doesn't happen anymore.
Issue observed in QCA9984 platform with firmware version:10.4-3.5.3-00053.
This Change tested in QCA9984 with firmware version: 10.4-3.5.3-00053 and

This patch only implements the optimisation "backend", it doesn't build

drm: Fix uabi regression by allowing garbage mode->type from userspace

There are several places in the ucma ABI where userspace can pass in a
sockaddr but set the address family to AF_IB. When that happens,
rdma_addr_size() will return a size bigger than sizeof struct sockaddr_in6,
and the ucma kernel code might end up copying past the end of a buffer
not sized for a struct sockaddr_ib.
Fix this by introducing new variants
int rdma_addr_size_in6(struct sockaddr_in6 *addr);
int rdma_addr_size_kss(struct __kernel_sockaddr_storage *addr);
that are type-safe for the types used in the ucma ABI and return 0 if the
size computed is bigger than the size of the type passed in. We can use
these new variants to check what size userspace has passed in before
copying any addresses.

fix iwlwifi_dev_ucode_error tracepoint to pass pointer to a table
instead of all 17 arguments by value.
dvm/main.c and mvm/utils.c have 'struct iwl_error_event_table'
defined with very similar yet subtly different fields and offsets.
tracepoint is still common and using definition of 'struct iwl_error_event_table'
from dvm/commands.h while copying fields.
Long term this tracepoint probably should be split into two.

- convert 'type array[]' tracepoint arguments into 'type *array',
since compiler will warn that sizeof('type array[]') == sizeof('type *array')
and later should be used instead
The CAST_TO_U64 macro in the later patch will enforce that tracepoint
arguments can only be integers, pointers, or less than 8 byte structures.
Larger structures should be passed by reference.
