Hi Luis,
probably the zero-day build already told you, but just in case:
Your commit 'drivers/video/fbdev/atyfb: Replace MTRR UC hole with strong UC'
causes build errors for architectures which don't support ioremap_uc.
This affects at least the alpha architecture, though there may be others.
Yep, parisc allmodconfig now sees it as well. Bisected before seeing
this message.
3cc2dac5be3f23414a4efdee0b26d79bed297cac is the first bad commit

I submitted a fix for it, can you tell me your linux-next tree?
http://server.roeck-us.net:8010/builders/next-alpha-next
next-20150729 to next-20150731.
Great thanks, I sent a proposal general fix, that should be tested first.
If all the bots say go for it, then yay, otherwise a simple
#define ioremap_uc ioremap_nocache
would be the way to go, but I would prefer to fix this sort of thing for good.
I just replied to your patch - it doesn't work.
We already know that parisc is also affected, and with
some experimentation I found that ia64 is affected as well.
