Since commit 23c85094fe18 ("proc/kcore: add vmcoreinfo note to /proc/kcore")
the kernel has exported the vmcoreinfo PT_NOTE on /proc/kcore as well
as /proc/vmcore.
arm64 only exposes it's additional arch information via
arch_crash_save_vmcoreinfo() if built with CONFIG_KEXEC, as kdump was
previously the only user of vmcoreinfo.
Move this weak function to a separate file that is built at the same
time as its caller in kernel/crash_core.c. This ensures values like
'kimage_voffset' are always present in the vmcoreinfo PT_NOTE.

All other uses of "asm goto" go through asm_volatile_goto, which avoids
a miscompile when using GCC < 4.8.2. Replace our open-coded "asm goto"
statements with the asm_volatile_goto macro to avoid issues with older

This reverts commit 375899cddcbb26881b03cb3fbdcfd600e4e67f4a.
The visibility of early messages did not longer take into account
"quiet", "debug", and "loglevel" early parameters.
It would be possible to invalidate and recompute LOG_NOCONS flag
for the affected messages. But it would be hairy.
Instead this patch just reverts the problematic commit. We could
come up with a better solution for the original problem. For example,
we could simplify the logic and just mark messages that should always
be visible or always invisible on the console.
Also this patch reverts the related build fix commit ffaa619af1b06
("printk: Fix warning about unused suppress_message_printing").
Finally, this patch does not put back the unused LOG_NOCONS flag.

Building drivers/mtd/nand/raw/nandsim.c on arch/hexagon/ produces a
printk format build warning. This is due to hexagon's ffs() being
coded as returning long instead of int.
Fix the printk format warning by changing all of hexagon's ffs() and
fls() functions to return int instead of long. The variables that
they return are already int instead of long. This return type
matches the return type in <asm-generic/bitops/>.

Doug Smythies says:
Sometimes it is desirable to temporarily disable, or clear,
the iptables rule set on a computer being controlled via a
secure shell session (SSH). While unwise on an internet facing
computer, I also do it often on non-internet accessible computers
while testing. Recently, this has become problematic, with the
SSH session being dropped upon re-load of the rule set.
The problem is that when all rules are deleted, conntrack hooks get
unregistered.
In case the rules are re-added later, its possible that tcp window
has moved far enough so that all packets are considered invalid (out of
window) until entry expires (which can take forever, default
established timeout is 5 days).
Fix this by clearing maxwin of existing tcp connections on register.
v2: don't touch entries on hook removal.
v3: remove obsolete expiry check.

Committing a transaction can consume some metadata of it's own, we now
reserve a small amount of metadata to cover this. Free metadata
reported by the kernel will not include this reserve.
If any of the reserve has been used after a commit we enter a new
internal state PM_OUT_OF_METADATA_SPACE. This is reported as
PM_READ_ONLY, so no userland changes are needed. If the metadata
device is resized the pool will move back to PM_WRITE.
These changes mean we never need to abort and rollback a transaction due
to running out of metadata space. This is particularly important
because there have been a handful of reports of data corruption against
DM thin-provisioning that can all be attributed to the thin-pool having
ran out of metadata space.

This fixes a NULL pointer dereference that can happen if the UDL
driver is unloaded before the framebuffer is initialized. This can
happen e.g. if the USB device is unplugged right after it was plugged
in.
As explained by Stéphane Marchesin:
It happens when fbdev is disabled (which is the case for Chrome OS).
Even though intialization of the fbdev part is optional (it's done in
udlfb_create which is the callback for fb_probe()), the teardown isn't
optional (udl_driver_unload -> udl_fbdev_cleanup ->
udl_fbdev_destroy).
Note that udl_fbdev_cleanup *tries* to be conditional (you can see it
does if (!udl->fbdev)) but that doesn't work, because udl->fbdev is
always set during udl_fbdev_init.

Two patches from the R40 display pipeline support series weren't applied
with the rest of the series. When they did get applied, the -rc6
deadline for drm-misc-next had past, so they didn't get into 4.19-rc1
with the rest of the series. However, the two patches are crucial in
the parsing of the R40's display pipeline graph in the device tree.
Without them, the driver crashes because it can't follow the odd graph
structure.
This patch removes the R40 compatibles from the sun4i-drm driver,
effectively disabling DRM support for the R40 for one release cycle.
This will prevent the driver from crashing upon probing.
The compatibles should be reinstated for the next release.

When there's no scaling requested ->is_unity should be true no matter
the format.
Also, when no scaling is requested and we have a multi-planar YUV
format, we should leave ->y_scaling[0] to VC4_SCALING_NONE and only
set ->x_scaling[0] to VC4_SCALING_PPF.
Doing this fixes an hardly visible artifact (seen when using modetest

This reverts commit a81cf9799ad7299b03a4dff020d9685f9ac5f3e0.
The patch causes a regression, which I cannot find the reason for.
So let's revert for now, as a revert hurts only performance.
Original report:
I was trying to resolve the problem with Oliver but we don't get any conclusion
for 5 months, so I am now sending this to mail list and cdc_acm authors.
I am using simple request-response protocol to obtain the boiller parameters
in constant intervals.
A simple one transaction is:
1. opening the /dev/ttyACM0
2. sending the following 10-bytes request to the device:
unsigned char req[] = {0x02, 0xfe, 0x01, 0x05, 0x08, 0x02, 0x01, 0x69, 0xab, 0x03};
3. reading response (frame of 74 bytes length).
4. closing the descriptor
I am doing this transaction with 5 seconds intervals.
Before the bad commit everything was working correctly: I've got a requests and
a responses in a timely manner.
After the bad commit more time I am using the kernel module, more problems I have.
The graph [2] is showing the problem.
As you can see after module load all seems fine but after about 30 minutes I've got
a plenty of EAGAINs when doing read()'s and trying to read back the data.
When I rmmod and insmod the cdc_acm module again, then the situation is starting
over again: running ok shortly after load, and more time it is running, more EAGAINs
I have when calling read().
As a bonus I can see the problem on the device itself:
The device is configured as you can see here on this screen [3].
It has two transmision LEDs: TX and RX. Blink duration is set for 100ms.
This is a recording before the bad commit when all is working fine: [4]
And this is with the bad commit: [5]
As you can see the TX led is blinking wrongly long (indicating transmission?)
and I have problems doing read() calls (EAGAIN).

Quectel EP06 (and EM06/EG06) supports dynamic configuration of USB
interfaces, without the device changing VID/PID or configuration number.
When the configuration is updated and interfaces are added/removed, the
interface numbers change. This means that the current code for matching
EP06 does not work.
This patch removes the current EP06 interface number match, and replaces
it with a match on class, subclass and protocol. Unfortunately, matching
on those three alone is not enough, as the diag interface exports the
same values as QMI. The other serial interfaces + adb export different
values and do not match.
The diag interface only has two endpoints, while the QMI interface has
three. I have therefore added a check for number of interfaces, and we
ignore the interface if the number of endpoints equals two.

David Miller says:
====================
SKB list handling cleanups
This is a preparatory patch series which cleans up various forms of
sloppy SKB list handling, and makes certain semantics explicit.
We are trying to eliminate code that directly accesses the SKB
list and SKB queue head next/prev members in any way. It is
impossible to convert SKB queue head over the struct list_head
while such code exists.
This patch series does not eliminate all such code, only the simplest
cases. A latter series will tackle the complicated ones.
A helper is added to make the "skb->next == NULL means not on a list"
rule explicit, and another is added to combine this with list_del().

The gasket in-kernel framework, recently introduced under staging,
re-implements what is already long-time provided by the UIO
subsystem, with extra PCI BAR remapping and MSI conveniences.
Before moving it out of staging, make sure we add the new bits to
the UIO framework instead, then transform its signle client, the
Apex driver, to a proper UIO driver (uio_driver.h).
