Low-power 589f59b52a Workaround for Linux PowerPC GPL-only cpu_has_feature() ... Linux since 4.7 makes interface 'cpu_has_feature' to use jump labels on powerpc if CONFIG_JUMP_LABEL_FEATURE_CHECKS is enabled, in this case however the inline function references GPL-only symbol 'cpu_feature_keys'. ZFS currently uses 'cpu_has_feature' either directly or indirectly from several places; while it is unknown how this issue didn't break ZFS on 64-bit little-endian powerpc, it is known to break ZFS with many Linux versions on both 32-bit and 64-bit big-endian powerpc. Until this issue is fixed in Linux, we have to workaround it by overriding affected inline functions without depending on 'cpu_feature_keys'.
