  riscv: Move alternative length validation into subsection (2022-06-02 15:55:22 -0700)

----------------------------------------------------------------
RISC-V Patches for the 5.19 Merge Window, Part 2

This is mostly some DT updates, but also a handful of cleanups and some
fixes.  The most user-visible of those are:

* A device tree for the Sundance Polarberry, along with a handful of
  fixes and clenups to the PolarFire SOC device trees and bindings.
* The memfd_secret syscall number is now visible to userspace,
* Some improvements to the vm layout dump, which really should have
  followed shortly after the sv48 patches but I missed.
