The m68k Kconfig tries to select a symbol (APM_EMULATION) that doesn't exist.


I did this to fix it, without really understanding the larger problem.  (Did

APM go away?)  Just FYI...

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.

^^^^^

I.e. PPC, not m68k.
