Linus Torvalds b0bb1269b9 RISC-V Patches for the 5.2 Merge Window, Part 1 v3
This patch set contains an assortment of RISC-V related patches that I'd
 like to target for the 5.2 merge window.  Most of the patches are
 cleanups, but there are a handful of user-visible changes:
 
 * The nosmp and nr_cpus command-line arguments are now supported, which
   work like normal.
 * The SBI console no longer installs itself as a preferred console, we
   rely on standard mechanisms (/chosen, command-line, hueristics)
   instead.
 * sfence_remove_sfence_vma{,_asid} now pass their arguments along to the
   SBI call.
 * Modules now support BUG().
 * A missing sfence.vma during boot has been added.  This bug only
   manifests during boot.
 * The arch/riscv support for SiFive's L2 cache controller has been
   merged, which should un-block the EDAC framework work.
 
 I've only tested this on QEMU again, as I didn't have time to get things
 running on the Unleashed.  The latest master from this morning merges in
 cleanly and passes the tests as well.
 
 This patch set rebased my "5.2 MW, Part 1" patch set which includes an
 erronous empty file.  It's also a rebase of my "5.2 MW, Part 2" patch
 set, in which I managed to create another file while attempting to
 remove the empty file.
 
 Sorry for all the noise!

README

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 Restructured Text 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.
