My E5-2600 Uncore Perf. Mon. Guide, March 2012 (Ref.# 327043-001)
doesn't seem to list events 0x26 and up. 

I'm staring at 2.8.5, table 2-108.

Is my document out-dated or what's up?

the r3qpi table seems to match, but the cbox one is funny again, event
0x01 doesn't appear in the doc, nor does 0x3b, 0x38, 0x23.

FWIW, cbox event constraint 0x1f needs to be an
EVENT_CONSTRAINT_OVERLAP, see the comment near that macro definition.
