[PATCH] powerpc: Add/remove/update properties in /proc/device-tree
Add support to the proc_device_tree file for removing and updating properties. Remove just removes the proc file, update changes the data pointer within the proc file. The remainder of the device-tree changes occur elsewhere. Signed-off-by: Dave Boutcher <sleddog@us.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
