[PATCH] powerpc: Use the ibm,pa-features property if available
Forthcoming IBM machines will have a "ibm,pa-features" property on CPU nodes, that contains bits indicating which optional architecture features are implemented by the CPU. This adds code to use the property, if present, to update our CPU feature bitmaps. Note that this means we can both set and clear feature bits based on what the firmware tells us. This is based on a patch by Will Schmidt <willschm@us.ibm.com>. Signed-off-by: Paul Mackerras <paulus@samba.org>
