Linus Torvalds 527cd20771 RISC-V changes for 4.17
This tag 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.
