[ Upstream commit e98d9ee64ee2cc9b1d1a8e26610ec4d0392ebe50 ]
For M_CAN peripherals, m_can_rx_handler() was called with quota = 1,
which caused any error handling to block RX from taking place until
the next time the IRQ handler is called. This had been observed to
cause RX to be blocked indefinitely in some cases.
This is fixed by calling m_can_rx_handler with a sensibly high quota.

[ Upstream commit c0e399f3baf42279f48991554240af8c457535d1 ]
Message loss from RX FIFO 0 is already handled in
m_can_handle_lost_msg(), with netdev output included.
Removing this warning also improves driver performance under heavy
load, where m_can_do_rx_poll() may be called many times before this
interrupt is cleared, causing this message to be output many
times (thanks Mariusz Madej for this report).

Currently doing modprobe c_can_pci will make the kernel complain:

[ Upstream commit 7c6e6bce08f918b64459415f58061d4d6df44994 ]
Under certain circumstances, when switching from Kvaser's linuxcan driver
(kvpciefd) to the SocketCAN driver (kvaser_pciefd), the bus load reporting
is not disabled.
This is flooding the kernel log with prints like:
[3485.574677] kvaser_pciefd 0000:02:00.0: Received unexpected packet type 0x00000009
Always put the controller in the expected state, instead of assuming that
bus load reporting is inactive.
Note: If bus load reporting is enabled when the driver is loaded, you will
still get a number of bus load packages (and printouts), before it is
disabled.

[ Upstream commit bf0ffea336b493c0a8c8bc27b46683ecf1e8f294 ]
"x25_close" is called by "hdlc_close" in "hdlc.c", which is called by
hardware drivers' "ndo_stop" function.
"x25_xmit" is called by "hdlc_start_xmit" in "hdlc.c", which is hardware
drivers' "ndo_start_xmit" function.
"x25_rx" is called by "hdlc_rcv" in "hdlc.c", which receives HDLC frames
from "net/core/dev.c".
"x25_close" races with "x25_xmit" and "x25_rx" because their callers race.
However, we need to ensure that the LAPB APIs called in "x25_xmit" and
"x25_rx" are called before "lapb_unregister" is called in "x25_close".
This patch adds locking to ensure when "x25_xmit" and "x25_rx" are doing
their work, "lapb_unregister" is not yet called in "x25_close".
Reasons for not solving the racing between "x25_close" and "x25_xmit" by
calling "netif_tx_disable" in "x25_close":
1. We still need to solve the racing between "x25_close" and "x25_rx";
2. The design of the HDLC subsystem assumes the HDLC hardware drivers
have full control over the TX queue, and the HDLC protocol drivers (like
this driver) have no control. Controlling the queue here in the protocol
driver may interfere with hardware drivers' control of the queue.

[ Upstream commit 3a9ef3e11c5d33e5cb355b4aad1a4caad2407541 ]
When a QMI handle is initialized, an array of message handler
structures is provided, defining how any received message should
be handled based on its type and message ID. The QMI core code
traverses this array when a message arrives and calls the function
associated with the (type, msg_id) found in the array.
The array is supposed to be terminated with an empty (all zero)
entry though. Without it, an unsupported message will cause
the QMI core code to go past the end of the array.
Fix this bug, by properly terminating the message handler arrays
provided when QMI handles are set up by the IPA driver.

[ Upstream commit 148ddaa89d4a0a927c4353398096cc33687755c1 ]
While picking commit a8cd989e1a57 ("mmc: sdhci-msm: Warn about
overclocking SD/MMC") back to my tree I was surprised that it was
reporting warnings. I thought I fixed those! Looking closer at the
fix, I see that I totally bungled it (or at least I halfway bungled
it). The SD card clock got fixed (and that was the one I was really
focused on fixing), but I totally adjusted the wrong clock for eMMC.
Sigh. Let's fix my dumb mistake.
Now both SD and eMMC have floor for the "apps" clock.
This doesn't matter a lot for the final clock rate for HS400 eMMC but
could matter if someone happens to put some slower eMMC on a sc7180.
We also transition through some of these lower rates sometimes and
having them wrong could cause problems during these transitions.
These were the messages I was seeing at boot:
mmc1: Card appears overclocked; req 52000000 Hz, actual 100000000 Hz
mmc1: Card appears overclocked; req 52000000 Hz, actual 100000000 Hz

[ Upstream commit fc9e5020971d57d7d0b3fef9e2ab2108fcb5588b ]
The comment describing the timestamps layout in the packet buffer is
wrong and the code is actually retrieving the timestamp in Timer 1
reference instead of Timer 0. This hasn't been a big issue so far
because hardware is configured to report both timestamps using Timer 0
(see IGC_SRRCTL register configuration in igc_ptp_enable_rx_timestamp()
helper). This patch fixes the comment and the code so we retrieve the
timestamp in Timer 0 reference as expected.
This patch also takes the opportunity to get rid of the hw.mac.type check
since it is not required.

It is unclear what all devices this might affect, but presumably other

limit the list to the know affected devices if needed.

[ Upstream commit 7d7275b3e866cf8092bd12553ec53ba26864f7bb ]
The main purpose of l3 IRQs is to catch OCP bus access errors and identify
corresponding code places by showing call stack, so it's important to
handle L3 interconnect errors as fast as possible. On RT these IRQs will
became threaded and will be scheduled much more late from the moment actual
error occurred so showing completely useless information.
Hence, mark l3 IRQs as IRQF_NO_THREAD so they will not be forced threaded
on RT or if force_irqthreads = true.

commit 4edbe1d7bcffcd6269f3b5eb63f710393ff2ec7a upstream.
If there are not any dm devices, we need to zero the "dev" argument in
the first structure dm_name_list. However, this can cause out of
bounds write, because the "needed" variable is zero and len may be
less than eight.
Fix this bug by reporting DM_BUFFER_FULL_FLAG if the result buffer is
too small to hold the "nl->dev" value.

commit 8840e3bd981f128846b01c12d3966d115e8617c9 upstream.
To optimize some task deferring it until runtime resume unless someone
holds a runtime PM reference (because in this case the task can be done
w/o the overhead of runtime resume), we have to use the runtime PM
get-if-active logic: If the runtime PM usage count is 0 (and so
get-if-in-use would return false) the runtime suspend handler is not
necessarily called yet (it could be just pending), so the device is not
necessarily powered down, and so the runtime resume handler is not
guaranteed to be called.
The fence revocation depends on the above deferral, so add a
get-if-active helper and use it during fence revocation.
v2:
- Add code comment explaining the fence reg programming deferral logic
to i915_vma_revoke_fence(). (Chris)
- Add Cc: stable and Fixes: tags. (Chris)
- Fix the function docbook comment.

commit cd5297b0855f17c8b4e3ef1d20c6a3656209c7b3 upstream.
Nothing checks userptr.ro except this call to pup_fast, which means
there's nothing actually preventing userspace from writing to this.
Which means you can just read-only mmap any file you want, userptr it
and then write to it with the gpu. Not good.
The right way to handle this is FOLL_WRITE | FOLL_FORCE, which will
break any COW mappings and update tracking for MAY_WRITE mappings so
there's no exploit and the vm isn't confused about what's going on.
For any legit use case there's no difference from what userspace can
observe and do.

commit 538d2dd0b9920334e6596977a664e9e7bac73703 upstream.
Stop reporting SW_DOCK events because this breaks suspend-on-lid-close.
SW_DOCK should only be reported for docking stations, but all the DSDTs in
my DSDT collection which use the intel-vbtn code, always seem to use this
for 2-in-1s / convertibles and set SW_DOCK=1 when in laptop-mode (in tandem
with setting SW_TABLET_MODE=0).
This causes userspace to think the laptop is docked to a port-replicator
and to disable suspend-on-lid-close, which is undesirable.
Map the dock events to KEY_IGNORE to avoid this broken SW_DOCK reporting.
Note this may theoretically cause us to stop reporting SW_DOCK on some
device where the 0xCA and 0xCB intel-vbtn events are actually used for
reporting docking to a classic docking-station / port-replicator but
I'm not aware of any such devices.
Also the most important thing is that we only report SW_DOCK when it
reliably reports being docked to a classic docking-station without any
false positives, which clearly is not the case here. If there is a
chance of reporting false positives then it is better to not report
SW_DOCK at all.

Since commit 8e850f25b581 ("net: socionext: Stop PHY before resetting
netsec") netsec_netdev_init() power downs phy before resetting the
controller. However, the state is not restored once the reset is
complete. As a result it is not possible to bring up network on a
platform with Broadcom BCM5482 phy.
Fix the issue by restoring phy power state after controller reset is
complete.
