+    Add initial support for IBM POWER8 processor
+    
+    The IBM POWER8 processor (to be publicly announced at some
+    future date) has some preliminary support in libpfm with
+    a subset of native events.  These POWER8-related libpfm
+    changes were pulled into PAPI on July 3, so further updates
+    in PAPI were required to support this new processor.  This
+    patch adds that required support.  NOTE: Due to the fact
+    that only a subset of native events have been publicised
+    at this point (and pushed into libpfm), not all of the
+    usual PAPI preset events have corresponding native events.
+    The rest of the POWER8 native events will be pushed
+    upstream once they are verified, and then we can flesh out
+    the PAPI preset events.
+    
+    With this initial POWER8 support patch, 5 of the ctests
+    and ftests fail, compared to 3 when PAPI is run on a POWER7.
+    At least one of the failing testcases is due to testing
+    being done on an early POWER8 processor with some known
+    hardware problems. We presume the number of failing tests
+    will decrease once we have GA-level hardware to test on.
