From 98ae22e15b430bfed5def01ac1a88ec9396284c8 Mon Sep 17 00:00:00 2001 From: Michael Neuling Date: Wed, 13 Feb 2013 16:21:35 +0000 Subject: powerpc: Add helper functions for transactional memory context switching Here we add the helper functions to be used when context switching. These allow us to fully reclaim and recheckpoint a transaction. We introduce a new paca field called tm_scratch to help us store away register values when doing the low level tm reclaim register save.
