From 0344c6c5387ba335bba5a66fd44714b94c98573f Mon Sep 17 00:00:00 2001 From: Christian Krafft Date: Tue, 24 Oct 2006 18:31:24 +0200 Subject: [POWERPC] sysfs: add support for adding/removing spu sysfs attributes This patch adds two functions to create and remove sysfs attributes and attribute_group to all cpus. That allows to register sysfs attributes in a subdirectory like: /sys/devices/system/cpu/cpuX/group_name/what_ever This will be used by cbe_thermal to group all attributes dealing with thermal support in one directory.
