drm/i915/display: Fix dma_fence_wait_timeout() return value handling
dma_fence_wait_timeout returns a long type but the driver is
only using the lower 32 bits of the retval and discarding the
upper 32 bits.
This is particularly problematic if there are already signalled
or stub fences on some of the hw planes. In this case the
dma_fence_wait_timeout function will immediately return with
timeout value MAX_SCHEDULE_TIMEOUT (0x7fffffffffffffff) since
the fence is already signalled. If the driver only uses the lower
32 bits of this return value then it'll interpret it as an error
code (0xFFFFFFFF or (-1)) and skip the wait on the remaining fences.
This issue was first observed in the xe driver with the Android
compositor where the GPU composited layer was not properly waited
on when there were stub fences in other overlay planes resulting in
visual artifacts.

wifi: brcmfmac: fix EXTSAE WPA3 connection failure due to AUTH TX failure
For WPA3-SAE Connection in EXTSAE mode, the userspace daemon is allowed to
generate the SAE Auth frames. The driver uses the "mgmt_frame" FW IOVAR to
transmit this MGMT frame.
Before sending the IOVAR, the Driver is incorrectly treating the channel
number read from the FW as a frequency value and again attempts to convert
this into a channel number using ieee80211_frequency_to_channel().
This added an invalid channel number as part of the IOVAR request to the FW
And some FW which strictly expects a valid channel would return BAD_CHAN
error, while failing to transmit the driver requested SAE Auth MGMT frame.
Fix this in the CYW vendor specific MGMT TX cfg80211 ops handler, by not
treating the channel number read from the FW as frequency value and skip
the attempt to convert it again into a channel number.
Also fix this in the generic MGMT TX cfg80211 ops handler.

RISC-V: KVM: add SBI extension reset callback
Currently, only the STA extension needed a reset function but that's
going to be the case for FWFT as well. Add a reset callback that can
be implemented by SBI extensions.
The FWFT SBI extension will need to dynamically allocate memory and do
init time specific initialization. Add an init/deinit callbacks that
allows to do so.
We found at Vates that there are lot of spurious interrupts when
benchmarking the xen-net PV driver frontend. This issue appeared with a
patch that addresses security issue XSA-391 (b27d47950e48 "xen/netfront:
harden netfront against event channel storms"). On an iperf benchmark,
spurious interrupts can represent up to 50% of the interrupts.
Spurious interrupts are interrupts that are rised for nothing, there is
no work to do. This appends because the function that handles the
interrupts ("xennet_tx_buf_gc") is also called at the end of the request
path to garbage collect the responses received during the transmission
load.
The request path is doing the work that the interrupt handler should
have done otherwise. This is particurary true when there is more than
one vcpu and get worse linearly with the number of vcpu/queue.
Moreover, this problem is amplifyed by the penalty imposed by a spurious
interrupt. When an interrupt is found spurious the interrupt chip will
delay the EOI to slowdown the backend. This delay will allow more
responses to be handled by the request path and then there will be more
chance the next interrupt will not find any work to do, creating a new
spurious interrupt.
This causes performance issue. The solution here is to remove the calls
from the request path and let the interrupt handler do the processing of
the responses. This approch removes most of the spurious interrupts
(<0.05%) and also has the benefit of freeing up cycles in the request
path, allowing it to process more work, which improves performance
compared to masking the spurious interrupt one way or another.
This optimization changes a part of the code that is present since the
net frontend driver was upstreamed. There is no similar pattern in the
other xen PV drivers. Since the first commit of xen-netfront is a blob
that doesn't explain all the design choices I can only guess why this
specific mecanism was here. This could have been introduce to compensate
a slow backend at the time (maybe the backend was fixed or optimize
later) or a small queue. In 18 years, both frontend and backend gain lot
of features and optimizations that could have obsolete the feature of
reaping completions from the TX path.

This version doesn't provide the sta id, so we need to look it up -

But when we leave OMI, because of the P2P/TDLS activation, the P2P/TDLS
sta can already exist while we receive the notification from the FW.
This causes an error log which is incorrect.
Since OMI is only supported in SC, which is not shipped yet, no one will
use a FW with the old version.
Remove support for it.
The only difference between SC2 and SC2F is that they use a different

The firmware of SC2 implements the logic of selecting the right FSEQ
image to load, so there is no need for SC2F firmware image.
Stop loading it, and load SC2 image instead.

sysctl: Remove (very) old file changelog
These comments are older than 2003 and therefore do not bare any
relevance on the current state of the sysctl.c file. Remove them as they
confuse more than clarify.

sysctl: move cad_pid into kernel/pid.c
Move cad_pid as well as supporting function proc_do_cad_pid into
kernel/pic.c. Replaced call to __do_proc_dointvec with proc_dointvec
inside proc_do_cad_pid which requires the copy of the ctl_table to
handle the temp value.
This is part of a greater effort to move ctl tables into their
respective subsystems which will reduce the merge conflicts in
kernel/sysctl.c.

Input: sysrq: mv sysrq into drivers/tty/sysrq.c
Move both sysrq ctl_table and supported sysrq_sysctl_handler helper
function into drivers/tty/sysrq.c. Replaced the __do_proc_dointvec in
helper function with do_proc_dointvec_minmax as the former is local to
kernel/sysctl.c. Here we use the minmax version of do_proc_dointvec
because do_proc_dointvec is static and calling do_proc_dointvec_minmax
with a NULL min and max is the same as calling do_proc_dointvec.

Add support for the TI TPS65214 PMIC with the addition of an id_table,
separate TPS65214 template_chip, and device-specific _change_direction
functions.
- Use platform_get_device_id() to assign dev-specific information.
- Use different change_direction() functions since TPS65214's GPIO
configuration bits are changeable during device operation through bit
GPIO_CONFIG in GENERAL_CONFIG register.
- Remove MODULE_ALIAS since it is now generated by MODULE_DEVICE_TABLE.

TPS65215 and TPS65219 are overlapping PMIC devices. While their regulator
features differe, the GPIO features are the same. In the TPS65219 MFD
driver, the 2 PMICs share the same "tps65219-gpio" compatible string to
limit support for TPS65215 in this GPIO driver to comments.
The TPS6521X_GPIO0_IDX and TPS6521X_GPIO0_OFFSET macro name prefixes are
updated to indicate these macros apply to both PMICs.
