Yes, it does help.  Thanks.


For BINFMT_ELF (not your example of COMPAT_BINFMT_ELF)
in Linux 3.5, I see this:


BEFORE PATCH:

type: boolean
unknown property: symbol
    dep: MMU && (BROKEN || !FRV)
prompt: Kernel support for ELF binaries
    dep: MMU && (BROKEN || !FRV)
default: y
    dep: MMU && (BROKEN || !FRV)

defined at fs/Kconfig.binfmt:1



AFTER PATCH:

type: boolean
unknown property: symbol
    dep: ( MMU y && (BROKEN n || !FRV FRV) ) =y
prompt: Kernel support for ELF binaries
    dep: ( MMU y && (BROKEN n || !FRV FRV) ) =y
default: y
    dep: ( MMU y && (BROKEN n || !FRV FRV) ) =y

defined at fs/Kconfig.binfmt:1




The added y/n/m are clear, but the "!FRV FRV" is confusing,
isn't it?
