Linus Torvalds dbf8381731 RISC-V Patches for the 5.9 Merge Window, Part 1
We have a lot of new kernel features for this merge window:
 
 * ARCH_SUPPORTS_ATOMIC_RMW, to allow OSQ locks to be enabled.
 * The ability to enable NO_HZ_FULL
 * Support for enabling kcov, kmemleak, stack protector, and VM debugging.
 * JUMP_LABEL support.
 
 There are also a handful of cleanups.
 
 next points out a trivial Kconfig merge conflict.  I don't see any way to have
 done this better: the symbols are sorted, it just happens that
 HAVE_COPY_THREAD_TLS was in the middle of two new symbols.  In case it helps
 any, here's a pretty current conflict resolution:
