#     powerpc: Drop unused CONFIG_PPC_HAS_FEATURE_CALLS
#     
#     Since ~2002 we have had CONFIG_PPC_HAS_FEATURE_CALLS defined as a faux
#     CONFIG symbol, firstly in include/asm-ppc/machdep.h, and then later
#     copied over to powerpc when ppc and ppc64 were merged.
#     
#     The last in-tree usage was removed in 2005 in commit
#     7bbd827750e6 ("[PATCH] ppc64: very basic desktop g5 sound support").
#     
#     I haven't been able to find any meaningful references to it anywhere
#     else, so I suspect it has been unused for many years. It confuses
#     scripts/checkkconfigsymbols.py, and seems to serve no purpose, so drop
#     it.
#     
#     Note that it's not in a uapi header, ie. it could only be used by
#     out-of-tree kernel modules, not general userspace code.
