pinctrl: samsung: Remove bogus irq_[un]mask from resource management
commit 3fa53ec2ed885b0aec3f0472e3b4a8a6f1cd748c upstream.
The irq chip callbacks irq_request/release_resources() have absolutely no
business with masking and unmasking the irq.
The core code unmasks the interrupt after complete setup and masks it
before invoking irq_release_resources().
The unmask is actually harmful as it happens before the interrupt is
completely initialized in __setup_irq().
Remove it.

pinctrl: sunxi: add a missing function of A10/A20 pinctrl driver
commit d81ece747d8727bb8b1cfc9a20dbe62f09a4e35a upstream.
The PH16 pin has a function with mux id 0x5, which is the DET pin of the
"sim" (smart card reader) IP block.
This function is missing in old versions of A10/A20 SoCs' datasheets and
user manuals, so it's also missing in the old drivers. The newest A10
Datasheet V1.70 and A20 Datasheet V1.41 contain this pin function, and
it's discovered during implementing R40 pinctrl driver.
Add it to the driver. As we now merged A20 pinctrl driver to the A10
one, we need to only fix the A10 driver now.

usb:xhci:Add quirk for Certain failing HP keyboard on reset after resume
commit e788787ef4f9c24aafefc480a8da5f92b914e5e6 upstream.
Certain HP keyboards would keep inputting a character automatically which
is the wake-up key after S3 resume
On some AMD platforms USB host fails to respond (by holding resume-K) to
USB device (an HP keyboard) resume request within 1ms (TURSM) and ensures
that resume is signaled for at least 20 ms (TDRSMDN), which is defined in
USB 2.0 spec. The result is that the keyboard is out of function.
In SNPS USB design, the host responds to the resume request only after
system gets back to S0 and the host gets to functional after the internal
HW restore operation that is more than 1 second after the initial resume
request from the USB device.
As a workaround for specific keyboard ID(HP Keyboards), applying port reset
after resume when the keyboard is plugged in.

commit 7496cfe5431f21da5d27a8388c326397e3f0a5db upstream.
Moshi USB to Ethernet Adapter internally uses a Genesys Logic hub to
connect to Realtek r8153.
The Realtek r8153 ethernet does not work on the internal hub, no-lpm quirk
can make it work.
Since another r8153 dongle at my hand does not have the issue, so add
the quirk to the Genesys Logic hub instead.

USB: Check for dropped connection before switching to full speed
commit 94c43b9897abf4ea366ed4dba027494e080c7050 upstream.
Some buggy USB disk adapters disconnect and reconnect multiple times
during the enumeration procedure. This may lead to a device
connecting at full speed instead of high speed, because when the USB
stack sees that a device isn't able to enumerate at high speed, it
tries to hand the connection over to a full-speed companion
controller.
The logic for doing this is careful to check that the device is still
connected. But this check is inadequate if the device disconnects and
reconnects before the check is done. The symptom is that a device
works, but much more slowly than it is capable of operating.
The situation was made worse recently by commit 22547c4cc4fe ("usb:
hub: Wait for connection to be reestablished after port reset"), which
increases the delay following a reset before a disconnect is
recognized, thus giving the device more time to reconnect.
This patch makes the check more robust. If the device was
disconnected at any time during enumeration, we will now skip the
full-speed handover.

iio: light: tsl2563: use correct event code
commit a3507e48d3f99a93a3056a34a5365f310434570f upstream.
The TSL2563 driver provides three iio channels, two of which are raw ADC
channels (channel 0 and channel 1) in the device and the remaining one
is calculated by the two. The ADC channel 0 only supports programmable
interrupt with threshold settings and this driver supports the event but
the generated event code does not contain the corresponding iio channel
type.
This is going to change userspace ABI. Hopefully fixing this to be
what it should always have been won't break any userspace code.

Make usb_hc_died() clear the HCD_FLAG_RH_RUNNING flag for the shared

the primary one.
Among other thigs, this prevents check_root_hub_suspended() from
returning -EBUSY for dead HCDs which helps to work around system
suspend issues in some situations.
This actually fixes occasional suspend failures on one of my test

fuse: initialize the flock flag in fuse_file on allocation
commit 68227c03cba84a24faf8a7277d2b1a03c8959c2c upstream.
Before the patch, the flock flag could remain uninitialized for the
lifespan of the fuse_file allocation. Unless set to true in
fuse_file_flock(), it would remain in an indeterminate state until read in
an if statement in fuse_release_common(). This could consequently lead to
taking an unexpected branch in the code.
The bug was discovered by a runtime instrumentation designed to detect use
of uninitialized memory in the kernel.

mm: ratelimit PFNs busy info message
commit 75dddef32514f7aa58930bde6a1263253bc3d4ba upstream.
The RDMA subsystem can generate several thousand of these messages per
second eventually leading to a kernel crash. Ratelimit these messages
to prevent this crash.
Doug said:
"I've been carrying a version of this for several kernel versions. I
don't remember when they started, but we have one (and only one) class
of machines: Dell PE R730xd, that generate these errors. When it
happens, without a rate limit, we get rcu timeouts and kernel oopses.
With the rate limit, we just get a lot of annoying kernel messages but
the machine continues on, recovers, and eventually the memory
operations all succeed"
And:
"> Well... why are all these EBUSY's occurring? It sounds inefficient
> (at least) but if it is expected, normal and unavoidable then
> perhaps we should just remove that message altogether?
I don't have an answer to that question. To be honest, I haven't
looked real hard. We never had this at all, then it started out of the
blue, but only on our Dell 730xd machines (and it hits all of them),
but no other classes or brands of machines. And we have our 730xd
machines loaded up with different brands and models of cards (for
instance one dedicated to mlx4 hardware, one for qib, one for mlx5, an
ocrdma/cxgb4 combo, etc), so the fact that it hit all of the machines
meant it wasn't tied to any particular brand/model of RDMA hardware.
To me, it always smelled of a hardware oddity specific to maybe the
CPUs or mainboard chipsets in these machines, so given that I'm not an
mm expert anyway, I never chased it down.
A few other relevant details: it showed up somewhere around 4.8/4.9 or
thereabouts. It never happened before, but the prinkt has been there
since the 3.18 days, so possibly the test to trigger this message was
changed, or something else in the allocator changed such that the
situation started happening on these machines?
And, like I said, it is specific to our 730xd machines (but they are
all identical, so that could mean it's something like their specific
ram configuration is causing the allocator to hit this on these
machine but not on other machines in the cluster, I don't want to say
it's necessarily the model of chipset or CPU, there are other bits of
identicalness between these machines)"
