The Goodix panel triggers an interrupt on touch events. However, its
registers will contain the valid values a short time after the
interrupt, and not when it's raised. At that moment, the 'buffer status'
bit is set.
Previously, if the 'buffer status' bit was not set when the registers
were read, the data was discarded and no input event was emitted,
causing "finger down" or "finger up" events to be missed sometimes.
This went unnoticed until v4.9, as the DesignWare I2C driver commonly
used with this driver had enough latency for that bug to never trigger
until commit 2702ea7dbec5 ("i2c: designware: wait for disable/enable only
if necessary").
Now, in the IRQ handler we will poll (with a timeout) the 'buffer status'
bit and process the data of the panel as soon as this bit gets set.
Note that the Goodix panel will send a few spurious interrupts after the
'finger up' event, in which the 'buffer status' bit will never be set.

Currently, enabling keypad interrupts is one of the first operations
done on the keypad, even before the interrupt is requested, so there is
a small time window where the keypad can fire interrupts but the driver
is not yet ready to handle them. It's fine for level interrupts because
they will be handled anyway, but not so much for edge ones.
This commit modifies and moves the function in charge of configuring the
keypad. Enabling interrupts is now the last thing done on the keypad,
and after the interrupt has been requested by the driver.
Writing to the config register was also used to determine if the device
was indeed present on the bus or not, this has been replaced by reading
the lock/event count register to keep the same functionality.

The commit 78bcac7b2ae1e ("Input: add support for the STMicroelectronics
FingerTip touchscreen) used the 'touchscreen_parse_properties()' helper
function in order to get the value of common properties.
But, commit 78bcac7b2ae1e didn't set the capability of ABS_MT_POSITION_*
before calling touchscreen_parse_properties(). In result, the max_x and
max_y of 'struct touchscreen_properties' were not set.

Step config setting for 5 wire touchscreen is incorrect for Y coordinates.
It was broken while we moved to DT. If you look close at the offending
commit bb76dc09ddfc ("input: ti_am33x_tsc: Order of TSC wires, made
configurable"), the change was:
- STEPCONFIG_XNP | STEPCONFIG_YPN;
+ ts_dev->bit_xn | ts_dev->bit_yp;
while bit_xn = STEPCONFIG_XNN and bit_yp = STEPCONFIG_YNN. Not quite the
same.

HDMI Mode selection on CNL is on CFGCR0 for that PLL, not
on in a global CTRL1 as it was on SKL.
The original patch addressed this difference, but leaving behind
this single entry here. So we were checking the wrong bits during
the PLL initialization and consequently avoiding the CFGCR1 setup
during HDMI initialization. Luckly when only HDMI was in use BIOS
had already setup this for us. But the dual display with hot plug
were messed up.

On PLL Enable sequence we need to "Configure DPCLKA_CFGCR0 to turn on
the clock for the DDI and map the DPLL to the DDI"
So we first do the map and then we unset DDI_CLK_OFF to turn the clock
on. We do this in 2 separated steps.
However, on this second step where we should only unset the off bit we are
also unmapping the ddi from the pll. So we end up using the pll 0
for almost everything. Consequently breaking cases with more than one
display.

In the full-ppgtt world, we can fill the GGTT full of context objects.
These context objects are currently implicitly tracked by the requests
that pin them i.e. they are only unpinned when the request is completed
and retired, but we do not have the link from the vma to the request
(anymore). In order to unpin those contexts, we have to issue another
request and wait upon the switch to the kernel context.
The bug during eviction was that we assumed that a full GGTT meant we
would have requests on the GGTT timeline, and so we missed situations
where those requests where merely in flight (and when even they have not
yet been submitted to hw yet). The fix employed here is to change the
already-is-idle test to no look at the execution timeline, but count the
outstanding requests and then check that we have switched to the kernel
context. Erring on the side of overkill here just means that we stall a
little longer than may be strictly required, but we only expect to hit
this path in extreme corner cases where returning an erroneous error is
worse than the delay.
v2: Logical inversion when swapping over branches.

RFC791 specifies the minimum MTU to be 68, while xen-net{front|back}
drivers use a minimum value of 0.
When set MTU to 0~67 with xen_net{front|back} driver, the network
will become unreachable immediately, the guest can no longer be pinged.
xen_net{front|back} should not allow the user to set this value which causes
network problems.

We have implemented delayed ring mmio switch mechanism to reduce
unnecessary mmio switch. While the vGPU is being destroyed or
detached from VM, we need to force the ring switch to host context.
The later deadline is missed. Then it got a chance that word load
from VM2 might execute under the ring context of VM1 which was
attached to a same vGPU instance. Finally, the GPU is hang.
This patch guarantee the two deadline are performed.

We have seen NULL-pointer dereference crashes in tty->disc_data when the
N_TTY fallback driver failed to open during hangup. The immediate cause
of this open to fail has been addressed in the preceding patch to
vmalloc(), but this code could be more robust.
As Alan pointed out in commit 8a8dabf2dd68 ("tty: handle the case where
we cannot restore a line discipline"), the N_TTY driver, historically
the safe fallback that could never fail, can indeed fail, but the
surrounding code is not prepared to handle this. To avoid crashes he
added a new N_NULL driver to take N_TTY's place as the last resort.
Hook that fallback up to the hangup path. Update tty_ldisc_reinit() to
reflect the reality that n_tty_open can indeed fail.

When I execute numactl -H (which reads /sys/devices/system/node/nodeX/cpumap
and displays cpumask_of_node for each node), I get different result
on X86 and arm64. For each numa node, the former only displayed online
CPUs, and the latter displayed all possible CPUs. Unfortunately, both
Linux documentation and numactl manual have not described it clear.
I sent a mail to ask for help, and Michal Hocko replied that he
preferred to print online cpus because it doesn't really make much sense
to bind anything on offline nodes.
Will said:
"I suspect the vast majority (if not all) code that reads this file was
developed for x86, so having the same behaviour for arm64 sounds like
something we should do ASAP before people try to special case with
things like #ifdef __aarch64__. I'd rather have this in 4.14 if
possible."
