the obvious problem with the above is that APM_EMULATION is defined in kernel/power/Kconfig arch-independently thusly:
config APM_EMULATION tristate "Advanced Power Management Emulation" depends on PM && SYS_SUPPORTS_APM_EMULATION help ... blah blah ...
but the Kconfig variable SYS_SUPPORTS_APM_EMULATION is defined for only a small subset of architectures:
$ grep "config SYS_SUPPORTS_APM_EMULATION" $(find . -name Kconfig*) ./arch/mips/Kconfig:config SYS_SUPPORTS_APM_EMULATION ./arch/sh/Kconfig:config SYS_SUPPORTS_APM_EMULATION ./arch/arm/Kconfig:config SYS_SUPPORTS_APM_EMULATION ./arch/powerpc/Kconfig:config SYS_SUPPORTS_APM_EMULATION
so there's a good chance that doing a kernel config with any other arch than those listed above that supports PM is going to generate the same warning.
