Waiman Long d387ceb171 locking/lockdep: Enforce PROVE_RAW_LOCK_NESTING only if ARCH_SUPPORTS_RT
Relax the rule to set PROVE_RAW_LOCK_NESTING by default only for arches
that supports PREEMPT_RT.  For arches that do not support PREEMPT_RT,
they will not be forced to address unimportant raw lock nesting issues
when they want to enable PROVE_LOCKING.  They do have the option
to enable it to look for these raw locking nesting problems if they
choose to.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
