RISC-V Patches for the 4.20 Merge Window, Part 2 v2

This tag contains the follow-on patches I'd like to target for the 4.20
merge window.  I'm being somewhat conservative here, as while there are
a few patches on the mailing list that were posted early in the merge
window I'd like to let those bake for another round -- this was a fairly
big release as far as RISC-V is concerened, and we need to walk before
we can run.

As far as the patches that made it go:

* A patch to ignore offline CPUs when calculating AT_HWCAP.  This should
  fix GDB on the HiFive unleashed, which has an embedded core for hart
  0 which is exposed to Linux as an offline CPU.
* A move of EM_RISCV to elf-em.h, which is where it should have been to
  begin with.
* I've also removed the 64-bit divide routines.  I know I'm not really
  playing by my own rules here because I posted the patches this
  morning, but since they shouldn't be in the kernel I think it's better
  to err on the side of going too fast here.

I don't anticipate any more patch sets for the merge window.

Changes since v1:

* Use a consistent base to merge from so the history isn't a mess.
