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. Signed-off-by: Michael Neuling <mikey@neuling.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
