Looking@the subject, that broke the 0day bot too. :-)

/me trims it.

Looks like we need __CHECKER__ ifdeffery somewhere but it is too late

I think the problem is that sparse can't parse the C11 _Generic thing.
Someone needs to teach it new tricks.

Ouch. The below should be all we need, assuming it's the best we can do
for sparse right now.

Very good, thank you! For 5.8 we probably still want the ifdef
__CHECKER__, otherwise we might break too many existing workflows. But
hopefully we can remove it again at some point. At the latest when the
kernel deprecates GCC 4.8 support, because then we can just remove the
whole unoptimized __unqual_scalar_typeof() definition.

Thanks,

[PATCH] add support for _Generic

[Luc Van Oostenryck]

It's slightly tested but is fine for the latest kernels
like https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git locking/kcsan

Note: a known difference with GCC is that it doesn't make the
      distinction between 'signed char' and a plain 'char'
      (on platforms where plain char are signed) since it's using
      the usual type compatbility like used for assignements.

Given there is some emergency, exceptionally, I've directly
