You have lots of false positives (or something) for arch/powerpc. Seems your script picked up #define names and comments that happen to match a Kconfig variable? And you have false positives on several CPU variables, as they are used within Kconfig files themselves to select different sets of options. For arch/ppc, the WANT_EARLY_SERIAL stuff was added by Al to fix those boards that unconditionally called early_serial_setup by selecting SERIAL_8250 in commit f08243a491f3e21feabbb04476a03fb0cbc975ff. Al, couldn't we just select SERIAL_8250 right in the board config instead? Of course, arch/ppc is dying soon-ish anyway so we might not even bother. josh -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
