From 9fa111372a54f695f65e0de2f2a2108fe6cf3584 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Thu, 17 Jul 2008 17:38:17 +0200 Subject: [PATCH] ftrace: fix lockup with MAXSMP MAXSMP brings in lots of use of various bitops in smp_processor_id() and friends - causing ftrace to lock up during bootup: calling anon_inode_init+0x0/0x130 initcall anon_inode_init+0x0/0x130 returned 0 after 0 msecs calling acpi_event_init+0x0/0x57 [ hard hang ] So exclude the bitops facilities from tracing.
