Rework the routines to convert a native statfs structure (with fixed-size 64-bit
counters) to a Linux statfs structure (with long-sized counters) for 32-bit apps.
Instead of following Linux and return an EOVERFLOW error from statfs() family of
syscalls when actual fs stat value(s) are large enough to not fit into 32 bits,
apply scale logics used by FreeBSD to convert a 5.x statfs structure to a 4.x
statfs structure.

It now returns a `struct scatterlist *` pointer instead of an error
code only.
The implementation is incomplete because it doesn't use the `prv`
argument.

At least one file in the DRM drivers benefits from some namespace
pollution to use `fs_reclaim_acquire()`/`fs_reclaim_release()`. They are
defined in `linux/sched/mm.h` and this header must be included
indirectly into the DRM drivers' source file.
I couldn't find how it was included. Therefore this commit includes
`linux/sched/mm.h` from `linux/sched.h`. This is not the case in Linux
but fixes the issue with the DRM drivers.

This is done by reverting CR4_PKE bit, because we perform %CR4
initialization in initializecpu(), and the function is called before
xsave_mask is read. To not redo the whole early initialization
sequence for the corner case, this should be good enough.

The functions are intended to report kernel variables that are
stored as sbintime_t (pointed to by arg1) as human readable
nanoseconds or milliseconds (reported via sysctl_handle_64).
The variable types and names were reversed. I guess there is
no functional change here, as all types flipped around were
signed 64. Note that these function aren't used yet anywhere
in the kernel.

The prevailing pattern seems to be to simply initialize all fields to
zero. Without this, it's possible to trigger a branch on uninitialized
memory, specifically, when testing nw->ignore_limit in
nlmsg_refill_buffer().
Initialize the writer structure in a couple of functions where this is
necessary.

The code comes from the i915 DRM driver.
In Linux commits b739f125e4ebd73d10ed30a856574e13649119ed and
b12d691ea5e01db42ccf3b4207e57cb3ce7cfe91 (Linux 5.13), the i915 DRM
driver dropped specific implementations to use Linux generic functions.
Therefore I moved the FreeBSD code from that i915 driver to linuxkpi.
However, these commits were later reverted (also in Linux 5.13) so the
i915 driver doesn't use these functions. But perhaps it will help in the
future.
To sum up, the code comes from the i915 DRM driver but it doesn't use it
(i.e. it continues to use its internal implementation).

The scmi driver in its current form requires the arm_doorbell
driver to communicate with the firmware.
The arm_doorbell is only found in ARM Juno reference board (and
apparently on Morello too).
If we want to use scmi on other platform (like some rockchip or imx
soc), the driver needs to be updated to support svc/shmem communication
with the firmware.
For now since it can be only used with arm_doorbell move the device to
std.arm otherwise kernel configs like ALLWINNER or ROCKCHIP fails to build.

Ever since gtaskqueue_drain() was added to iflib_stop(), a kernel panic
occurs when the ice(4) driver is in recovery mode. Queues are not
initialized in this mode, so gt_taskqueue is not initialized, and
gtaskqueue_drain() will panic.
Fix this by only doing a drain if an RX queue's gt_taskqueue is
initialized.
