Hi,
After commit f70ced0917 (blk-mq: support per-distpatch_queue flush
machinery), the mtip32xx driver may oops upon module load due to walking
off the end of an array in mtip_init_cmd. On initialization of the
flush_rq, init_request is called with request_index >= the maximum queue
depth the driver supports. For mtip32xx, this value is used to index
into an array. What this means is that the driver will walk off the end
of the array, and either oops or cause random memory corruption.
The problem is easily reproduced by doing modprobe/rmmod of the mtip32xx
driver in a loop. I can typically reproduce the problem in about 30
seconds.
Now, in the case of mtip32xx, it actually doesn't support flush/fua, so
I think we can simply return without doing anything. In addition, no
other mq-enabled driver does anything with the request_index passed into
init_request(), so no other driver is affected. However, I'm not really
sure what is expected of drivers. Ming, what did you envision drivers
would do when initializing the flush requests?

e79729123f ("writeback: don't issue wb_writeback_work if clean")
updated writeback path to avoid kicking writeback work items if there
are no inodes to be written out; unfortunately, the avoidance logic
was too aggressive and broke sync_inodes_sb().
* sync_inodes_sb() must write out I_DIRTY_TIME inodes but I_DIRTY_TIME
inodes dont't contribute to bdi/wb_has_dirty_io() tests and were
being skipped over.
* inodes are taken off wb->b_dirty/io/more_io lists after writeback
starts on them. sync_inodes_sb() skipping wait_sb_inodes() when
bdi_has_dirty_io() breaks it by making it return while writebacks
are in-flight.
This patch fixes the breakages by
* Removing bdi_has_dirty_io() shortcut from bdi_split_work_to_wbs().
The callers are already testing the condition.
* Removing bdi_has_dirty_io() shortcut from sync_inodes_sb() so that
it always calls into bdi_split_work_to_wbs() and wait_sb_inodes().
* Making bdi_split_work_to_wbs() consider the b_dirty_time list for
WB_SYNC_ALL writebacks.

Then, commit 4dea547fef ("phylib: rework to prepare for OF

At this point, it is somewhat unclear why the change was seen as
necessary. But, when we look at the device model tree in

their MDIO bus.
Change the PHY's parent device to be the MDIO bus device.

The I2C core always reports the MODALIAS uevent as "i2c:<modalias>"
regardless of the mechanism that was used to register the device
(i.e: OF or board code) and the table that is used later to match
the driver with the device (i.e: I2C id table or OF match table).
So drivers needs to export the I2C id table and this be built into
the module or udev won't have the necessary information to autoload
the needed driver module when the device is added.
But this means that OF-only drivers needs to have both OF and I2C id
tables that have to be kept in sync and also the dev node compatible
manufacturer prefix is stripped when reporting the MODALIAS. Which can
lead to issues if two vendors use the same I2C device name for example.
To avoid the above, the I2C core behavior may be changed in the future
to not require an SPI device table for OF-only drivers and report the
OF module alias. So, it's better to also export the OF table even when
is unused now to prevent breaking module loading when the core changes.

in
WARNING: CPU: 0 PID: 1 at kernel/workqueue.c:4418

or

It can be triggered with a bit of luck in Linux guests running

During the various CPU_ONLINE callbacks CPUn is online but not
active. Several things can go wrong at that point, depending on
the scheduling of tasks on CPU0.
Variant 1:
cpu_notify(CPU_ONLINE)
workqueue_cpu_up_callback()
rebind_workers()
set_cpus_allowed_ptr()
This call fails because it requires an active CPU; rebind_workers()
ends with a warning:

workqueue_cpu_up_callback()
Variant 2:

__kthread_unpark()
__kthread_bind()
wake_up_state()

select_task_rq()
select_fallback_rq()
The ->wake_cpu of the unparked thread is not allowed, making a call
to select_fallback_rq() necessary. Then, select_fallback_rq() cannot
find an allowed, active CPU and promptly resets the allowed CPUs, so
that the task in question ends up on CPU0.
When those unparked tasks are eventually executed, they run
immediately into a BUG:
kernel BUG at kernel/smpboot.c:135!
Just changing the order in which the online/active bits are set
(and adding some memory barriers), would solve the two issues
above. However, it would change the order of operations back to
the one before commit 6acbfb9697 ("sched: Fix hotplug vs.
set_cpus_allowed_ptr()"), thus, reintroducing that particular
problem.
Going further back into history, we have at least the following
commits touching this topic:
- commit 2baab4e904 ("sched: Fix select_fallback_rq() vs cpu_active/cpu_online")
- commit 5fbd036b55 ("sched: Cleanup cpu_active madness")
Together, these give us the following non-working solutions:
- secondary CPU sets active before online, because active is assumed to
be a subset of online;
- secondary CPU sets online before active, because the primary CPU
assumes that an online CPU is also active;
- secondary CPU sets online and waits for primary CPU to set active,
because it might deadlock.
Commit 875ebe940d ("powerpc/smp: Wait until secondaries are
active & online") introduces an arch-specific solution to this
arch-independent problem.
Now, go for a more general solution without explicit waiting and
simply set active twice: once on the secondary CPU after online
was set and once on the primary CPU after online was seen.

The widget power-saving code tries to turn up/down the power of each
widget in the I/O paths that are modified at each jack plug/unplug.
The recent report revealed that the power activation leaves some
widgets unpowered after plugging. This is because
snd_hda_activate_path() turns on path->active flag at the end of the
function while the path power management is done before that. Then
it's regarded as if nothing is active, and the driver turns off the
power.
The fix is simply to set the flag at the beginning of the function,
before trying to power up.

The structure is xin24m -> pll -> pll-mux (xin24m,pll,xin32k). The pll
does have an init callback to make sure the boot-selected frequency is
using the expected pll settings and resets the same frequency using
the values provided in the driver if necessary.
The setting itself also involves remuxing the pll-mux temporarily to
the xin24m source to let the new pll rate settle. Until now this worked
flawlessly, even when it had the flaw of accessing the mux settings
before the mux actually got registered.
With the recent clock-core conversions this flaw became apparent in
null pointer dereference in
[<c03fc400>] (clk_hw_get_num_parents) from [<c0400df0>] (clk_mux_get_parent+0x14/0xc8)
[<c0400ddc>] (clk_mux_get_parent) from [<c040246c>] (rockchip_rk3066_pll_set_rate+0xd8/0x320)
So to fix that, simply register the pll-mux before the pll, so that
it will be fully initialized when the pll clock executes its init-
callback and possibly touches the pll-mux clock.
