ia64 kbuild warning message

ia64 kbuild warning message

[Randy Dunlap]

Hi Yamada-san,

I am seeing this on ia64 builds:

../scripts/Makefile.build:68: 'arch/ia64/kernel/palinfo.ko' will not be built even though obj-m is specified.
../scripts/Makefile.build:69: You cannot use subdir-y/m to visit a module Makefile. Use obj-y/m instead.

with CONFIG_IA64_PALINFO=y

Can you explain, please?

thanks.

This warning is emitted in the archprepare stage.


The following code in arch/ia64/Makefile:

make_nr_irqs_h:
        $(Q)$(MAKE) $(build)=arch/ia64/kernel include/generated/nr-irqs.h



I am wondering if we could merge
arch/ia64/kernel/nr-irqs.c into
arch/ia64/kernel/asm-offsets.c

OK, I figured out how to clean this up.

I will send a patch set tomorrow.
For now, I need some sleep.
