+Hi Linus !
+
+Here's powerpc's batch for this merge window. Mostly bits and pieces,
+such as Anton doing some performance tuning left and right, and the
+usual churn. One hilight is the support for the new Freescale e5500 core
+(64-bit BookE). Another one is that we now wire up the whole lot of
+socket calls as direct syscalls in addition to the old style indirect
+method.
+
+Cheers,
+Ben.
