Add a "groupoom" cgroup v2 mount option to enable the cgroup-aware
OOM killer. If not set, the OOM selection is performed in
a "traditional" per-process way.
The behavior can be changed dynamically by remounting the cgroupfs.

Do not consider the fixed size of hv_vp_set when passing the variable
header size to hv_do_rep_hypercall().
The Hyper-V hypervisor specification states that for a hypercall with a

via the input control.

An explanation of what IMC stands for, both in description and in the
code, would be appreciated.

SDM 10.5.4.1 TSC-Deadline Mode mentioned that "Transitioning between
TSC-Deadline
mode and other timer modes also disarms the timer". So the APIC Timer Initial
Count
Register for one-shot/periodic mode should be reset. This patch do it.

Btw. here is how I would do the recursive oom badness. The diff is not
the nicest one because there is some code moving but the resulting code
is smaller and imho easier to grasp. Only compile tested though

If we take TSC-deadline mode timer out of the picture, the Intel SDM
does not say that the timer is disable when the timer mode is change,
either from one-shot to periodic or vice versa.
After this patch, the timer is no longer disarmed on change of mode, so

The description in the Intel SDM of how the divide configuration
register is used: "The APIC timer frequency will be the processor's bus
clock or core crystal clock frequency divided by the value specified in
the divide configuration register."
