[PATCH v5 0/1] Documentation: Add real-time kernel configuration guide

Hi,

There is a no "one size fits all" solution for configuring a PREEMPT_RT
kernel.

Intorduce a PREEMPT_RT kernel configuration guide to better help system
developers and integrators.

Changelog v5
------------

Handle Sebastian remarks:

- Reference other documents as Jonathan prefers; i.e., no :doc: tags.
- Coalesce the CPU frequency governors text, and the tracing text.
- Add might_sleep() note to CONFIG_DEBUG_ATOMIC_SLEEP.
- Mention debugfs only as "allowed".
- Mention CONFIG_DEBUG_BUGVERBOSE.
- Do not mention DEBUG_INFO as it's not selectable; mention the
  CONFIG_DEBUG_INFO* selectable variants.

Changelog v4
------------

Handle Sashiko review: Remove a no-longer-referenced link.  Remove
CONFIG_WQ_SYS reference, which I thought it exists due to a quick
misunderstanding of core-api/workqueue.

Changelog v3
------------

CONFIG_EFI_DISABLE_RUNTIME: Mention that system integrators can now assign
the efi_runtime workqueue CPU affinity, then safely pin RT tasks on a
different CPU range.  This is due to:

now being merged mainline.

------------

Handle Rostedt remarks:

Changelog v1
