When receiving an LRO packet, the checksum field is set by the hardware
to the checksum of the first coalesced packet. Obviously, this checksum
is not valid for the merged LRO packet and should be fixed. We can use
the CQE checksum which covers the checksum of the entire merged packet
TCP payload to help us calculate the checksum incrementally.
Tested by sending IPv4/6 traffic with LRO enabled, RX checksum disabled
and watching nstat checksum error counters (in addition to the obvious
bandwidth drop caused by checksum errors).
This bug is usually "hidden" since LRO packets would go through the
CHECKSUM_UNNECESSARY flow which does not validate the packet checksum.
It's important to note that previous to this patch, LRO packets provided
with CHECKSUM_UNNECESSARY are indeed packets with a correct validated
checksum (even though the checksum inside the TCP header is incorrect),
since the hardware LRO aggregation is terminated upon receiving a packet
with bad checksum.

MIPS' struct compat_flock doesn't match the 32-bit struct flock, as it
has an extra short __unused before pad[4], which combined with alignment
increases the size to 40 bytes compared with struct flock's 36 bytes.
Since commit 8c6657cb50 ("Switch flock copyin/copyout primitives to
copy_{from,to}_user()"), put_compat_flock() writes the full compat_flock
struct to userland, which results in corruption of the userland word
after the struct flock when running 32-bit userlands on 64-bit kernels.
This was observed to cause a bus error exception when starting Firefox

On dm3730 there are enumeration problems after resume.
Investigation led to the cause that the MUSB_POWER_SOFTCONN
bit is not set. If it was set before suspend (because it
was enabled via musb_pullup()), it is set in
musb_restore_context() so the pullup is enabled. But then
musb_start() is called which overwrites MUSB_POWER and
therefore disables MUSB_POWER_SOFTCONN, so no pullup is
enabled and the device is not enumerated.
So let's do a subset of what musb_start() does
in the same way as musb_suspend() does it. Platform-specific
stuff it still called as there might be some phy-related stuff
which needs to be enabled.
Also interrupts are enabled, as it was the original idea
of calling musb_start() in musb_resume() according to
Commit 6fc6f4b87c ("usb: musb: Disable interrupts on suspend,

This is problematic if a PMU IRQ is pending out of reset, as it may be
taken before we know the PMU, and thus the IRQ handler won't be able to

This issue was masked using legacy framebuffer and X11 modesetting, but
is clearly visible using gbm rendering when buffer is submitted late after
vblank, like using software decoding and OpenGL rendering in Kodi.
With this patch, tearing and other artifacts disappears completely.

One nasty very old crash around polling for buffers that aren't there
- though that can only cause effects on drivers that support events
but not buffers.
* buffer / kfifo handling in the core.
- Check there is a buffer and return 0 from poll directly if there
isn't. Poll doesn't make sense in this circumstances, but best to close
the hole.
* ad5933
- Change the marked buffer mode to a software buffer as the meaning of
the hardware buffer label has long since changed and this uses a front
end software buffer anyway.
* ad7192
- Fix the fact the external clock frequency was only set when using the
internal clock which was less than helpful.
* adis_lib
- Initialize the trigger before requesting the interrupt. Some newer
parts can power up with interrupt generation enabled so ordering now
matters.
* aspeed-adc
- Fix an errror handling path as labels and general ordering were wrong.
* srf08
- Fix a link error due to undefined devm_iio_triggered_buffer_setup.
* stm32-adc
- Fix error handling unwind squence in stm32h7_adc_enable.

This patch fixes issue of X-power extcon-axp288 and Intel extcon-int3496 driver.
- For extcon-int3496 driver,
Process id-pin first so that we start with the right status in order to fix
a race where the initial work might still be running while other drivers
were already calling extcon_get_state().
- For extcon-axp288 driver,
Revert the patch[1] which were applied to v4.16-rc1 because there are better
ways with usb-role-switch and constify the axp288_pwr_up_down_info array.

... since u64 has a hidden header dependency that was not there before
using it (i.e. it breaks our VMM build).
Also, __u64 is the right way to expose data types through UAPI.
