Today allmodconfig does not enable CONFIG_ACPI due to BE config, which

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 ?
Hi Anders,
Yeah, I got the idea.
So when you say "'make savedefconfig' CONFIG_CPU_BIG_ENDIAN will be
dropped", I don't know what the rules are in terms of resyncing the
common defconfig (I was under the impression that it's done per release
cycle by the arm soc maintainers, but can't find evidence as such), but
your change may be easily lost in this way.
Thanks,
John
