Arm and allyesconfig, allnoconfig, allmodconfig and randconfig

Arm and allyesconfig, allnoconfig, allmodconfig and randconfig

[Jack Stone]

Hi All,

I've been trying to compile the Arm port of the kernel and noticed that
allyesconfig etc. and randconfig don't seem to compile on Arm - they all
end up with build errors (mostly about missing preprocessor defines eg
__LINUX_ARM_ARCH__). Is this a known problem and if so can it be
documented somewhere?

As another data point I can compile the defconfigs fine.

I tried googling and greping the source for any reference to this but
couldn't see anything. Sorry if this has already been answered.

Thanks,

Jack

all*config are basically not supported on ARM.  (There are some, eg,
allmodconfig in conjunction with some defconfigs that might compile
but its very hit and miss.)

Patches welcome.

Is this the sort of thing you meant? I don't know if the text or
location is correct so comments are very welcome.

Document that ARM doesn't support all*config

From: Jack Stone <jwjstone@fastmail.fm>

ARM doesn't support all*config. This is because it does not make sense
as
there are so many different variants. Instead the defconfigs should be
used.
