Hi Linus,
Here are some regression fixes for kbuild:
- modversion support for exported asm symbols (Nick Piggin). The
affected architectures need separate patches adding asm-prototypes.h.
- fix rebuilds of lib-ksyms.o (Nick Piggin)
- -fno-PIE builds (Sebastian Siewior and Borislav Petkov). This is not a
kernel regression, but one of the Debian gcc package. Nevertheless,
it's quite annoying, so I think it should go into mainline and stable
now.
Thanks,
Michal

As the pull request's comment says, we do need the per-arch asm-prototypes.h
patches. I've just checked on x86: still broken with current mainline,
works with my patch from [email protected];
I suspect the arm counterpart (patch by Arnd Bergmann) is also needed
(you just commented on that thread).
