Hmm. Bisected to Andrew's big chunk of merges on April 1st. Right now I 
have

 - bad: 527410ff7fc5d45fe41523c0ba061113dea22017 ("cirrusfb: GD5446 
   fixes")

 - good: 63cd885426872254e82dac2d9e13ea4f720c21dc ("ntfs: remove private 
   wrapper of endian helpers")

and all the commits in between are all from that same -mm series. Very 
interesting. 

Anyway, the SLUB errors and the per-cpu'ness of the thing seems to have 
been a false lead and irrelevant. 

Andrew, I'll continue to bisect. Looks like it might be the epoll changes 
(that's the only really 'core' thing there). Although I don't understand 
why those would make that Mac Mini unhappy, but not affect the other 
machines. So maybe I should just stop guessing until the bisection ends..
