No, it didn't.
If not, please attach logs of make V=1 with clean Linus' tree and with

Thanks, can you also post a log without the revert?
The problem is that compiler options meant to be used only for the
compiling done by scripts/checksyscalls.sh are now leaking into the
compilation of other parts of the kernel (asm-offsets.c), where they
wreak havoc.
Something like the attached is what I think needs to be done.
