From 35589a8fa8138244e7f2ef9317c440aa580c9335 Mon Sep 17 00:00:00 2001 From: Keshavamurthy Anil S Date: Tue, 26 Sep 2006 12:03:13 -0700 Subject: [IA64] Move perfmon tables from thread_struct to pfm_context This patch renders thread_struct->pmcs[] and thread_struct->pmds[] OBSOLETE. The actual table is moved to pfm_context structure which saves space in thread_struct (in turn saving space in task_struct which frees up more space for kernel stacks).
