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.
lib: Remove umoddi3 and udivmoddi4
These were only necessary for an out-of-tree driver that has since been
fixed to use the proper divide routines. I've simply reverted the pair
of commits we made last week.
