[ Upstream commit fb48febce7e30baed94dd791e19521abd2c3fd83 ]
When the watchdog detects a disk change, it calls cancel_activity(),
which in turn tries to cancel the fd_timer delayed work.
In the above scenario, fd_timer_fn is set to fd_watchdog(), meaning
it is trying to cancel its own work.
This results in a hang as cancel_delayed_work_sync() is waiting for the
watchdog (itself) to return, which never happens.
This can be reproduced relatively consistently by attempting to read a
broken floppy, and ejecting it while IO is being attempted and retried.
To resolve this, this patch calls cancel_delayed_work() instead, which
cancels the work without waiting for the watchdog to return and finish.
Before this regression was introduced, the code in this section used
del_timer(), and not del_timer_sync() to delete the watchdog timer.

be a kernel warning about duplicated sysfs entries and the probing will
fail. This is because the nvmem device name is not unique. Make it

With commit 3873e2d7f63a ("drivers: PL011: refactor pl011_probe()") the
function devm_ioremap() called from pl011_setup_port() was replaced with
devm_ioremap_resource(). Since this function not only remaps but also
requests the ports io memory region it now collides with the .config_port()
callback which requests the same region at uart port registration.
Since devm_ioremap_resource() already claims the memory successfully, the
request in .config_port() fails.
Later at uart port deregistration the attempt to release the unclaimed
memory also fails. The failure results in a “Trying to free nonexistent
resource" warning.
Fix these issues by removing the callbacks that implement the redundant
memory allocation/release. Also make sure that changing the drivers io
memory base address via TIOCSSERIAL is not allowed any more.

[ Upstream commit 4a9af6cac050dce2e895ec3205c4615383ad9112 ]
The flushing of pending work in the EC driver uses drain_workqueue()
to flush the event handling work that can requeue itself via
advance_transaction(), but this is problematic, because that
work may also be requeued from the query workqueue.
Namely, if an EC transaction is carried out during the execution of
a query handler, it involves calling advance_transaction() which
may queue up the event handling work again. This causes the kernel
to complain about attempts to add a work item to the EC event
workqueue while it is being drained and worst-case it may cause a
valid event to be skipped.
To avoid this problem, introduce two new counters, events_in_progress
and queries_in_progress, incremented when a work item is queued on
the event workqueue or the query workqueue, respectively, and
decremented at the end of the corresponding work function, and make
acpi_ec_dispatch_gpe() the workqueues in a loop until the both of
these counters are zero (or system wakeup is pending) instead of
calling acpi_ec_flush_work().
At the same time, change __acpi_ec_flush_work() to call
flush_workqueue() instead of drain_workqueue() to flush the event
workqueue.
While at it, use the observation that the work item queued in
acpi_ec_query() cannot be pending at that time, because it is used
only once, to simplify the code in there.
Additionally, clean up a comment in acpi_ec_query() and adjust white
space in acpi_ec_event_processor().

Some thread flags can be set remotely, and so even when IRQs are disabled,
the flags can change under our feet. Thus, when setting flags we must use
an atomic operation rather than a plain read-modify-write sequence, as a
plain read-modify-write may discard flags which are concurrently set by a
remote thread, e.g.
// task A // task B
tmp = A->thread_info.flags;
set_tsk_thread_flag(A, NEWFLAG_B);
tmp |= NEWFLAG_A;
A->thread_info.flags = tmp;
arch/powerpc/kernel/interrupt.c's system_call_exception() sets
_TIF_RESTOREALL in the thread info flags with a read-modify-write, which
may result in other flags being discarded.
Elsewhere in the file it uses clear_bits() to atomically remove flag bits,
so use set_bits() here for consistency with those.
There may be reasons (e.g. instrumentation) that prevent the use of
set_thread_flag() and clear_thread_flag() here, which would otherwise be
preferable.

dwmac-qcom-ethqos currently exposes a mechanism to dump rgmii registers

we now let 'pm_runtime_put()' disable the clocks before returning from

This causes a crash when 'rgmii_dump()' register dumps are enabled,
as the clocks are already off.
Since other dwmac drivers (possible future users as well) might
require a similar register dump feature, introduce a platform level
callback to allow the same.
This fixes the crash noticed while enabling rgmii_dump() dumps in

to keep a invoking the register dump callback from the correct

Stop the CODA960 JPEG encoder from overflowing capture buffers.
The bitstream buffer overflow interrupt doesn't seem to be connected,
so this has to be handled via timeout instead.

[ Upstream commit 230d683ae04894933720425c8dead9508a09ebc3 ]
The JPEG encoder found in the Hantro H1 encoder block only produces a
raw entropy-encoded scan. The driver is responsible for building a JPEG
compliant bitstream and placing the entropy-encoded scan in it. Right
now the driver uses a bounce buffer for the hardware to output the raw
scan to.
In commit e765dba11ec2 ("hantro: Move hantro_enc_buf_finish to JPEG
codec_ops.done"), the code that copies the raw scan from the bounce
buffer to the capture buffer was moved, but was only hooked up for the
Hantro H1 (then RK3288) variant. The RK3399 variant was broken,
producing a JPEG bitstream without the scan, and the capture buffer's
.bytesused field unset.
Fix this by duplicating the code that is executed when the JPEG encoder
finishes encoding a frame. As the encoded length is read back from
hardware, and the variants having different register layouts, the
code is duplicated rather than shared.

hsfreqrange should be chosen based on the calculated mbps which
is closer to the default bit rate and within the range as per
table[1]. But current calculation always selects first value which
is greater than or equal to the calculated mbps which may lead
to chosing a wrong range in some cases.
For example for 360 mbps for H3/M3N
Existing logic selects
Calculated value 360Mbps : Default 400Mbps Range [368.125 -433.125 mbps]
This hsfreqrange is out of range.
The logic is changed to get the default value which is closest to the
calculated value [1]

While gcc 4.8.5 is too old to build the upstream kernel, it's possible it
could be used to build standalone libbpf which suffers from the same problem.
Silence the error by initializing 'err' to 0. The warning/error seems to be
a false positive since err is set early in the function. Regardless we
shouldn't prevent libbpf from building for this.

Commit 7cc4ffc55564 ("block, bfq: put reqs of waker and woken in
dispatch list") added a condition to bfq_insert_request() which added
waker's requests directly to dispatch list. The rationale was that
completing waker's IO is needed to get more IO for the current queue.
Although this rationale is valid, there is a hole in it. The waker does
not necessarily serve the IO only for the current queue and maybe it's
current IO is not needed for current queue to make progress. Furthermore
injecting IO like this completely bypasses any service accounting within
bfq and thus we do not properly track how much service is waker's queue
getting or that the waker is actually doing any IO. Depending on the
conditions this can result in the waker getting too much or too few
service.
Consider for example the following job file:
[global]
directory=/mnt/repro/
rw=write
size=8g
time_based
runtime=30
ramp_time=10
blocksize=1m
direct=0
ioengine=sync
[slowwriter]
numjobs=1
prioclass=2
prio=7
fsync=200
[fastwriter]
numjobs=1
prioclass=2
prio=0
fsync=200
Despite processes have very different IO priorities, they get the same
about of service. The reason is that bfq identifies these processes as
having waker-wakee relationship and once that happens, IO from
fastwriter gets injected during slowwriter's time slice. As a result bfq
is not aware that fastwriter has any IO to do and constantly schedules
only slowwriter's queue. Thus fastwriter is forced to compete with
slowwriter's IO all the time instead of getting its share of time based
on IO priority.
Drop the special injection condition from bfq_insert_request(). As a
result, requests will be tracked and queued in a normal way and on next
dispatch bfq_select_queue() can decide whether the waker's inserted
requests should be injected during the current queue's timeslice or not.

mode (usart, i2c, spi) via mode register (FLEX_MR). On i2c bus there might
be connected critical devices (like PMIC) which on suspend/resume should
be suspended/resumed at the end/beginning. i2c uses
.suspend_noirq/.resume_noirq for this kind of purposes. Align flexcom
to use .resume_noirq as it should be resumed before the embedded IPs.
