When building allmodconfig KCONFIG_ALLCONFIG=$(pwd)/arch/arm64/configs/defconfig

Today allmodconfig does not enable CONFIG_ACPI due to BE config, which
is quite unfortunate, I'd say.
right.
Rework so that we disable CONFIG_CPU_BIG_ENDIAN in the defcinfig file so
defconfig
thanks.
it doesn't get enabled when building allmodconfig kernels. When doing a
'make savedefconfig' CONFIG_CPU_BIG_ENDIAN will be dropped.
So without having to pass KCONFIG_ALLCONFIG or do anything else, what
about a config for CONFIG_CPU_LITTLE_ENDIAN instead? I'm not sure if
that was omitted for a specific reason.
Oh, I tried to elaborate on the idea in the cover letter, that using
the defconfig
as base and then configure the rest as modules is to get a bootable kernel
that have as many features turned on as possible. That will make it possible
to run as wide a range of testsuites as possible on a single kernel.
Does that make it clearer ?
