Comment 4 Jeff Law 2013-01-30 16:15:42 EST

It hasn't yet.  And (of course) the plan is to go upstream, then backport (assuming this BZ gets a full set of acks).  I just keep getting hijacked by other small stuff that's accumulated over time.

Comment 5 RHEL Product and Program Management 2013-02-03 01:47:45 EST

This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.

Comment 8 Jeff Law 2014-03-13 23:20:19 EDT

I do :-)  They stalled going upstream as reviews showed the ARM port has similar problems and I simply wasn't arm-aware enough to write those bits.

Are the two threads and should have a thorough analysis as well as the PPC patches.  They'll probably start to look familiar since you helped with the analysis.
