Commit cfe30b872058 "libnvdimm, pmem: adjust for section collisions with
'System RAM'" enabled Linux to workaround occasions where platform
firmware arranges for "System RAM" and "Persistent Memory" to collide
within a single section boundary. Unfortunately, as reported in this
issue [1], platform firmware can inflict the same collision between
persistent memory regions.
The approach of interrogating iomem_resource does not work in this
case because platform firmware may merge multiple regions into a single
iomem_resource range. Instead provide a method to interrogate regions
that share the same parent bus.
This is a stop-gap until the core-MM can grow support for hotplug on
sub-section boundaries.

Pull block fixes from Jens Axboe:
"A bit earlier in the week as usual, but there's a fix here that should
go in sooner rather than later.
Under a combination of circumstance, the direct issue path in blk-mq
could corrupt data. This wasn't easy to hit, but the ones that are
affected by it, seem to hit it pretty easily. Full explanation in the
patch. None of the regular filesystem and storage testing has
triggered it, even though it's been around since 4.19-rc1.
Outside of that, whitelist trim tweak for certain Samsung devices for
libata"

When reading an extra descriptor, we need to properly check the minimum
and maximum size allowed, to prevent from invalid data being sent by a
device.

serial8250_register_8250_port calls uart_config_port, which calls
config_port on the port before it tries to power on the port. So we need
the port to be on before calling serial8250_register_8250_port. Change
the code to always do a runtime resume in probe before registering port,
and always do a runtime suspend in remove.
This basically reverts the change in commit 68e5fc4a255a ("tty: serial:
8250_mtk: use pm_runtime callbacks for enabling"), but still use
pm_runtime callbacks.

The USB-serial console implementation has never reported the actual
terminal settings used. Despite storing the corresponding cflags in its
struct console, these were never honoured on later tty open() where the
tty termios would be left initialised to the driver defaults.
Unlike the serial console implementation, the USB-serial code calls
subdriver open() already at console setup. While calling set_termios()
and write() before open() looks like it could work for some USB-serial
drivers, others definitely do not expect this, so modelling this after
serial core is going to be intrusive, if at all possible.
Instead, use a (renamed) tty helper to save the termios data used at
console setup so that the tty termios reflects the actual terminal
settings after a subsequent tty open().
Note that the calls to tty_init_termios() (tty_driver_install()) and
tty_save_termios() are serialised using the disconnect mutex.
This specifically fixes a regression that was triggered by a recent
change adding software flow control to the pl2303 driver: a getty trying
to disable flow control while leaving the baud rate unchanged would now
also set the baud rate to the driver default (prior to the flow-control
change this had been a noop).

This reverts commit 3aa2177e47878f7e7616da8a2050c44f22301b6e.
That commit triggered a new WARN when unloading the module (see at the
end of the commit message). When a class_dev is embedded in a structure
then that class_dev is the thing that controls the lifetime of that
structure, for that reason device managed allocations can't be used here.
See Documentation/kobject.txt.
Revert the above patch, so the struct is allocated using kzalloc and we
have a release function for it that frees the allocated memory, otherwise
it is broken.
------------[ cut here ]------------
Device 'cros_ec' does not have a release() function, it is broken and must be fixed.

Some lower volume SanDisk Ultra Flair in 16GB, which the VID:PID is
in 0781:5591, will aggressively request LPM of U1/U2 during runtime,
when using this thumb drive as the OS installation key we found the
device will generate failure during U1 exit path making it dropped
from the USB bus, this causes a corrupted installation in system at
the end.
i.e.,

...
Analyzed the USB trace in the link layer we realized it is because
of the 6-ms timer of tRecoveryConfigurationTimeout which documented
on the USB 3.2 Revision 1.0, the section 7.5.10.4.2 of "Exit from
Recovery.Configuration"; device initiates U1 exit -> Recovery.Active
-> Recovery.Configuration, then the host timer timeout makes the link
transits to eSS.Inactive -> Rx.Detect follows by a Warm Reset.
Interestingly, the other higher volume of SanDisk Ultra Flair sharing
the same VID:PID, such as 64GB, would not request LPM during runtime,
it sticks at U0 always, thus disabling LPM does not affect those thumb
drives at all.
The same odd occures in SanDisk Ultra Fit 16GB, VID:PID in 0781:5583.

The problem is caused by use of a static array to store
environment-string pointers. When the routine is called by multiple
threads concurrently, the pointers from one thread can overwrite those
from another.
The solution is to use an ordinary automatic array instead of a static
array.

The driver defines three states for a cppi channel.
- idle: .chan_busy == 0 && not in .pending list
- pending: .chan_busy == 0 && in .pending list
- busy: .chan_busy == 1 && not in .pending list
There are cases in which the cppi channel could be in the pending state
when cppi41_dma_issue_pending() is called after cppi41_runtime_suspend()
is called.
cppi41_stop_chan() has a bug for these cases to set channels to idle state.
It only checks the .chan_busy flag, but not the .pending list, then later
when cppi41_runtime_resume() is called the channels in .pending list will
be transitioned to busy state.
Removing channels from the .pending list solves the problem.

The dmaengine documentation states that device_terminate_all may be
asynchronous and need not wait for the active transfers to stop.
This allows us to move most of the functionality currently implemented
in the sdma channel termination function to run in a worker, outside
of any atomic context. Moving this out of atomic context has two
benefits: we can now sleep while waiting for the channel to terminate,
instead of busy waiting and the freeing of the dma descriptors happens
with IRQs enabled, getting rid of a warning in the dma mapping code.
As the termination is now async, we need to implement the
device_synchronize dma engine function which simply waits for the
worker to finish its execution.

This reverts commit fe5b85c656bc. The SDMA engine needs the descriptors to
be contiguous in memory. As the dma pool API is only able to provide a
single descriptor per alloc invocation there is no guarantee that multiple
descriptors satisfy this requirement. Also the code in question is broken
as it only allocates memory for a single descriptor, without looking at the
number of descriptors required for the transfer, leading to out-of-bounds
accesses when the descriptors are written.

When the armada thermal module is inserted, removed and then reinserted,
the system panics as per the messages below. The reason is that "edit"
a live resource in the resource tree twice, and end up with it pointing
to some other hardware.
Editing live resources (resources that are part of the registered
resource tree) is not permissible - the resource tree is an ordered
set of resources, sorted by start address, and when a new resource is
inserted, it is validated that it (a) fits within its parent resource
and (b) does not overlap a neighbouring resource.
Get rid of this resource editing. We can instead adjust the return
value from ioremap() as ioremap() deals with the creation of page-
based mappings - provided the adjustment does not cross a page
boundary.

The mvpp2_phylink_validate() relies on the interface field of
phylink_link_state to determine valid link modes. However, when called
from phylink_sfp_module_insert() this field in not initialized. The
default switch case then excludes 10G link modes. This allows 10G SFP
modules that are detected correctly to be configured at max rate of
2.5G.
Catch the uninitialized PHY mode case, and allow 10G rates.

Commit 8c0e64ac4075 ("thermal: armada: get rid of the ->is_valid()
pointer") removed the unnecessary indirection through a function
pointer, but in doing so, also removed the negation operator too:
- if (priv->data->is_valid && !priv->data->is_valid(priv)) {
+ if (armada_is_valid(priv)) {
which results in:
armada_thermal f06f808c.thermal: Temperature sensor reading not valid
armada_thermal f2400078.thermal: Temperature sensor reading not valid
armada_thermal f4400078.thermal: Temperature sensor reading not valid
at boot, or whenever the "temp" sysfs file is read. Replace the
negation operator.

After getting a reference to the platform device's of_node the probe
function ends up calling of_find_matching_node() using the node as an
argument. The function takes care of decreasing the refcount on it. We
are then incorrectly decreasing the refcount on that node again.
This patch removes the unwarranted call to of_node_put().

[Why]
New GCC warnings for stringop-truncation and stringop-overflow help
catch common misuse of strncpy. This patch suppresses these warnings
by fixing bugs identified by them.
[How]
Since the parameter passed for name in amdpgu_dm_create_common_mode has
no fixed length, if the string is >= DRM_DISPLAY_MODE_LEN then
mode->name will not be null-terminated.
The truncation in fill_audio_info won't actually occur (and the string
will be null-terminated since the buffer is initialized to zero), but
the warning can be suppressed by using the proper buffer size.
This patch fixes both issues by using the real size for the buffer and
making use of strscpy (which always terminates).

Commit 78139c94dc8c ("net: vhost: lock the vqs one by one") moved the vq
lock to improve scalability, but introduced a possible deadlock in
vhost-iotlb. vhost_iotlb_notify_vq() now takes vq->mutex while holding
the device's IOTLB spinlock. And on the vhost_iotlb_miss() path, the
spinlock is taken while holding vq->mutex.
Since calling vhost_poll_queue() doesn't require any lock, avoid the
deadlock by not taking vq->mutex.

This patch adds toggling phy reset if PHY is not attached. Otherwise,
some boards (e.g. R-Car H3 Salvator-XS) cannot link up correctly if
we do the following method:
1) Kernel boots by using initramfs.
--> No open the nic, so phy_device_register() and phy_probe()
deasserts the reset.
2) Kernel enters the suspend.
--> So, keep the reset signal as deassert.
--> On R-Car Salvator-XS board, unfortunately, the board power is
turned off.
3) Kernel returns from suspend.
4) ifconfig eth0 up
--> Then, since edge signal of the reset doesn't happen,
it cannot link up.
5) ifconfig eth0 down
6) ifconfig eth0 up
--> In this case, it can link up.

In tun.c skb->len was accessed while doing stats accounting after a
call to netif_receive_skb. We can not access skb after this call
because buffers may be dropped.
The fix for this bug would be to store skb->len in local variable and
then use it after netif_receive_skb(). IMO using xdp data size for
accounting bytes will be better because input for tun_xdp_one() is
xdp_buff.
Hence this patch:
- fixes a bug by removing skb access after netif_receive_skb()
- uses xdp data size for accounting bytes

It's not the same as in 7fe0ee09 patch described.
As 8139cp uses shared irq mode, other device irq will trigger
cp_interrupt to execute.
cp_change_mtu
-> cp_close
-> cp_open
In cp_close routine just before free_irq(), some interrupt may occur.
In my environment, cp_interrupt exectutes and IntrStatus is 0x4,
exactly TxOk. That will cause cp_tx to wake device queue.
As device queue is started, cp_start_xmit and cp_open will run at same
time which will cause kernel BUG.
For example:
[#] for tx descriptor
At start:
[#][#][#]
num_queued=3
After cp_init_hw->cp_start_hw->netdev_reset_queue:
[#][#][#]
num_queued=0
When 8139cp starts to work then cp_tx will check
num_queued mismatchs the complete_bytes.
The patch will check IntrMask before check IntrStatus in cp_interrupt.
When 8139cp interrupt is disabled, just return.

Currently __set_phy_supported allows to add modes w/o checking whether
the PHY supports them. This is wrong, it should never add modes but
only remove modes we don't want to support.
The commit marked as fixed didn't do anything wrong, it just copied
existing functionality to the helper which is being fixed now.

These devices support read zero after trim (RZAT), as they advertise to
the OS. However, the OS doesn't believe the SSDs unless they are
explicitly whitelisted.

I noticed that the Android v3.0.8 kernel on droid4 is using different
keypad values from the mainline kernel and does not have issues with
keys occasionally being stuck until pressed again. Turns out there was
an earlier patch posted to fix this as "Input: omap-keypad: errata i689:
Correct debounce time", but it was never reposted to fix use macros
for timing calculations.
This updated version is using macros, and also fixes the use of the
input clock rate to use 32768KiHz instead of 32000KiHz. And we want to
use the known good Android kernel values of 3 and 6 instead of 2 and 6
in the earlier patch.

Since we continue to find tons of new variants [0,1,2,3,4,5,6] that
need the PDP quirk, let's just quirk all devices from PDP.

Noticed the other day the trackpoint felt different on my P50, then
realized it was because rmi4 wasn't loading for this machine
automatically. Suspend/resume, hibernate, and everything else seem to
work perfectly fine on here.
