Implement default core scheduling policy.
- fork() / clone(): inherit cookie from parent
- exec(): if cookie then new cookie
Did that exec() thing want to change cookie on suid instead, just like
perf_event_exit_task() ?
Note that sched_core_fork() is called from under tasklist_lock, and

The IMX8MQ got two VPUs but until now only G1 has been enabled.
This series aim to add the second VPU (aka G2) and provide basic
HEVC decoding support.
To be able to decode HEVC it is needed to add/update some of the
structures in the uapi. In addition of them one HANTRO dedicated
control is requ
This capability will allow the user to know which KVM_GUESTDBG_* bits
are supported.

While device_add() will happen to catch dev_set_name() failures it is a
broken pattern to follow given that the core may try to fall back to a
different name.
Add explicit checking for dev_set_name() failures to be cleaned up by
put_device(). Skip cdev_device_add() and proceed directly to

Add dma to the reg offsets struct.
This will allow different products to have a different reg offset for this
particular module.

Hi!
I would like to publish two debug features which were needed for other stuff
I work on.
One is the reworked lx-symbols script which now actually works on at least
gdb 9.1 (gdb 9.2 was reported to fail to load the debug symbols from the kernel
for some reason, not related to this patch) and up
While none the CXL sysfs attributes are threatening to overrun a
PAGE_SIZE of output, it is good form to use the recommended helpers.
