Need a space(s) after '15.', and the public description doesn't have
a "Multiply-add FLOPS." in it. Pretty sure I'd do the consolidation
trick here, too.

Needs a space after that first "FLOPS."
Also the before/after concatentation convention changed between here
and the last one: pick one and be consistent across the board.

I thought we agreed to call these LS MAB Allocates by Type", like the text in the
later PPR for AMD Family 17h Model 31h B0 - 55803 Rev 0.54 - Sep 12, 2019?
DC Miss By Type is probably less correct given the MAB != DC, and the name of
the event is "LsMabAlloc".
FWIW, a MAB is a Miss address buffer (seen in the Model 71h PPR's MCA_CTL_LS
register definition).

I see each of the two tablewalkers got consolidated into their own
unit mask groups? Any reason we couldn't leave the original
instances there, and add these in addition? In any case we'd need
clarification of which 'side' are the both counting - I or D - in
a single BriefDescription here.

Another case where it's hard to make out what the event is counting
in general: Make its PublicDescription a single Breifdescription?
