From 8b3c34cf0e0ab334a24aad7367cd06a5ba09a898 Mon Sep 17 00:00:00 2001 From: Michael Neuling Date: Wed, 13 Feb 2013 16:21:32 +0000 Subject: powerpc: New macros for transactional memory support This adds new macros for saving and restoring checkpointed architected state from and to the thread_struct. It also adds some debugging macros for when your brain explodes trying to debug your transactional memory enabled kernel.
