I was about to submit my replacement, just to find that this was committed
during my night. I have to admit that I absolutely do not understand the
need for rushing here; I thought I said quite clearly that I will come
forward with a patch dealing with two issues in one go. Now I need to go
and re-base my change, because all of what this patch touches is also
touched by my change, as the 2nd issue (the pointless presence of
asm/numa.h and the need for RISC-V to introduce a 3rd instance if nothing
is done up front) is still there.
