ah, indeed - the rename:

  4aeb0b4: perfcounters: rename struct hw_perf_counter_ops into struct pmu

changed context lines in your patch causing the fuzz. The mechanic 
rename changed quite a bit of stuff in the powerpc driver - we were 
lucky that your rather large patch still merged cleanly.

Btw, if in the future such renames cause problems for any pending 
patch of yours we can always pick up your patches first and then 
re-do the rename.
