Pull RISC-V fixes from Palmer Dabbelt:
- A fix for cacheinfo DT probing to avoid reading non-boolean
properties as booleans.
- A fix for cpufeature to use bitmap_equal() instead of memcmp(), so
unused bits are ignored.
- Fixes for cmpxchg and futex cmpxchg that properly encode the sign
extension requirements on inline asm, which results in spurious
successes. This manifests in at least inode_set_ctime_current, but is
likely just a disaster waiting to happen.
- A fix for the rseq selftests, which was using an invalid constraint.
- A pair of fixes for signal frame size handling:
- We were reserving space for an extra empty extension context
header on systems with extended signal context, thus resulting in
unnecessarily large allocations.
- We weren't properly checking for available extensions before
calculating the signal stack size, which resulted in undersized
stack allocations on some systems (at least those with T-Head
custom vectors).
Also, we've added Alex as a reviewer. He's been helping out a ton
lately, thanks!

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.
