This KPI was removed in d223372545. Note that there are a handful of
references remaining in the src tree to these rtalloc functions that
could be cleaned up by someone with more domain knowledge.

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

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.

Several important base system components are written in C++, and the

Just accept this, and remove the option to build without C++ support.

The prevailing pattern seems to be to simply initialize all fields to
