( Note, i'm re-using this old MD pull request thread to report a bug in a pull 
  request you sent to Linus in the past two days. I havent found the pull 
  request nor the patch on lkml. )

All 32-bit x86 builds (x86, allyesconfig) that enable RAID are failing with 
this build failure:

 drivers/built-in.o: In function `raid5_compute_sector':
 raid5.c:(.text+0x2e42ac): undefined reference to `__umoddi3'
 raid5.c:(.text+0x2e42d8): undefined reference to `__umoddi3'
 raid5.c:(.text+0x2e42ff): undefined reference to `__umoddi3'
 raid5.c:(.text+0x2e4327): undefined reference to `__umoddi3'
 raid5.c:(.text+0x2e4385): undefined reference to `__umoddi3'
 drivers/built-in.o:raid5.c:(.text+0x2e43bc): more undefined references to `__umoddi3' follow

Caused by this commit:

  35f2a59: md/raid5: allow for more than 2^31 chunks.

I've reverted the commit from -tip for now.

Thanks,

	Ingo
