From 6a274c08f2f4dfac7167bbd849621f3a2b55d424 Mon Sep 17 00:00:00 2001 From: Michael Neuling Date: Wed, 2 Jul 2008 14:06:37 +1000 Subject: powerpc: Clean up copy_to/from_user for vsx and fpr This merges and cleans up some of the ugly copy/to from user code which is required for the new fpr and vsx layout in the thread_struct. Also fixes some hard coded buffer sizes and removes a redundant fpr_flush_to_thread.
