    Merge tag 'riscv-for-linus-4.17-mw0' of git://git.kernel.org/pub/scm/linux/kernel/git/palmer/riscv-linux
    
    Pull RISC-V updates from Palmer Dabbelt:
     "This contains the new features we'd like to incorporate into the
      RISC-V port for 4.17. We might have a bit more stuff land later in the
      merge window, but I wanted to get this out earlier just so everyone
      can see where we currently stand.
    
      A short summary of the changes is:
    
       - We've added support for dynamic ftrace on RISC-V targets.
    
       - There have been a handful of cleanups to our atomic and locking
         routines. They now more closely match the released RISC-V memory
         model draft.
    
       - Our module loading support has been cleaned up and is now enabled
         by default, despite some limitations still existing.
    
       - A patch to define COMMANDLINE_FORCE instead of COMMANDLINE_OVERRIDE
         so the generic device tree code picks up handling all our command
         line stuff.
    
      There's more information in the merge commits for each patch set"
