Revision 5d7ead0039b0c9500825b46997896352810efb0b authored by Michael Ellerman on 13 July 2013, 02:53:40 UTC, committed by Benjamin Herrenschmidt on 24 July 2013, 04:18:45 UTC
The presence or absence of EBB is advertised to userspace via the presence
or absence of PPC_FEATURE2_EBB in cpu_user_features2.

Because the kernel can be built without PMU support, we should only add
PPC_FEATURE2_EBB to cpu_user_features2 when we successfully register the
power8 PMU support.
