When you set an option to `=y` but one of its dependencies is set to `=m`, then
`make oldconfig` will reset it back to `=m` as well.

AVX-512 components use could cause core turbo frequency drop. So
it's useful to expose AVX-512 usage elapsed time as a heuristic hint
for the user space job scheduler to cluster the AVX-512 using tasks
together.
Tensorflow example:
$ while [ 1 ]; do cat /proc/tid/arch_status | grep AVX512; sleep 1
We have NUMA Balancing feature which always trying to move pages

* page cache can't be handled
* no cgroup level balancing
Suppose we have a box with 4 cpu, two cgroup A & B each running 4 tasks,
below scenery could be easily observe
This patch introduced numa locality statistic, which try to imply
the numa balancing efficiency per memory cgroup.
By doing 'cat /sys/fs/cgroup/memory/CGROUP_PATH/memory.numa_stat', we
see new output line heading with 'locality', the format is:
locality 0~9% 10%~19% 20%~29% 30%~39% 40%~49% 50%~
This patch introduced numa execution information, to imply the numa
efficiency.
By doing 'cat /sys/fs/cgroup/memory/CGROUP_PATH/memory.numa_stat', we
see new output line heading with 'exectime', like:
exectime 24399843 27865444
which means the tasks of this cgroup executed 24399843 ticks on no
This patch add a new entry 'numa_preferred' for each memory cgroup,
by which we can now override the memory policy of the tasks inside
a particular cgroup, combined with numa balancing, we now be able to
migrate the workloads of a cgroup to the specified numa node, in gentle
way.
The load balancin
Now we have the way to estimate and adjust numa preferred node for each
memcg, next problem is how to use them.
Usually one will bind workloads with cpuset.cpus, combined with cpuset.mems
or maybe better the memory policy to achieve numa bonus, however in complicated
scenery like combined type of
numa balancer is a module which will try to automatically adjust numa
balancing stuff to gain numa bonus as much as possible.
For each memory cgroup, we process the work in two steps:
On stage 1 we check cgroup's exectime and memory topology to see
if there could be a candidate for settled down,

2016 and 2017 MacBook Pro's have a T1 chip that drives the Touch Bar,
ambient light sensor, webcam, and fingerprint sensor; this shows up
as an iBridge USB device in the system. These patches provide initial
support for the Touch Bar and ALS - the webcam is already handled by
existing drivers, and
This driver enables basic touch bar functionality: enabling it, switching
between modes on FN key press, and dimming and turning the display
off/on when idle/active.

The iBridge device provides access to several devices, including:
- the Touch Bar
- the iSight webcam
- the light sensor
- the fingerprint sensor
This driver provides the core support for managing the iBridge device
and the access to the underlying devices. In particular, since the

On 2016/2017 MacBook Pro's with a Touch Bar the ALS is attached to,
and exposed via the iBridge device. This provides the driver for that
sensor.

crashkernel=xM tries to reserve crashkernel memory under 4G, which
is enough for usual cases. But this could fail sometimes, for example
one tries to reserve a big chunk like 2G, it is possible to fail.
So let the crashkernel=xM just fall back to use high memory in case it

Commit a939bb57cd47 ("pinctrl: intel: implement gpio_irq_enable") was
added because clearing interrupt status bit is required to avoid
unexpected behavior.
Turns out the unmask callback also needs the fix, which can solve weird
IRQ triggering issues on I2C touchpad ELAN1200.

Add i.MX8QXP SoC driver support, introduce driver dependency
into Kconfig as CONFIG_IMX_SCU must be selected to support
i.MX8QXP, also need to use platform driver model to make sure
IMX_SCU driver is probed before i.MX8 SoC driver.
With this patch, SoC info can be read from sysfs:

Current code always set pmic->rinfo[id] = &max77620_regs_info[id];
It should set to either max77620_regs_info or max20024_regs_info
depends on the chip_id.
