Hi,
It's getting pretty old to have see and type cur_cpu_spec->cpu_features
& CPU_FTR_<feature>, when a shorter and less TLA-ridden macro is more
readable.
This also takes care of the differences between PPC and PPC64 cpu
features for the common code; most places in PPC could be replaced with
the macro as well.
