From 92614610774072ea68131f16e024ee8fc15be9be Mon Sep 17 00:00:00 2001 From: Len Brown Date: Wed, 22 Apr 2009 19:28:15 -0400 Subject: ACPI: delete obsolete "bus master activity" proc field Linux-2.6.29 deleted the legacy ACPI idle handler, leaving the CPU_IDLE handler, which does not track bus master activity. So delete the unused bm_activity field -- it is confusing to print an always zero value. This patch could break programs that parse /proc/acpi/processor/*/power, since it deletes this line from that file: bus master activity: 00000000 http://bugzilla.kernel.org/show_bug.cgi?id=13145 is not fixed by this patch, but provoked this patch.
