[PATCH 0/3] ia64: clean-up header dependency and build process, fix build warning

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Randy Dunlap reports the following warning with CONFIG_IA64_PALINFO=m:

../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.

This comes from the fact Kbuild descends into arch/ia64/kernel/ twice.

First, to generate <generated/nr-irqs.h>,
Second, to build kernel and module objects.

The warning is emitted in the first descend because it is not the
intended usage.

I looked into the code closely, and noticed arch/ia64/kernel/nr-irqs.c
was not needed in the first place.

It was separated out of arch/ia64/kernel/asm-offsets.c just because
<asm/mca.h> was including too many bogus headers.

IA64 is not actively maintained, and there exists unneeded obsolete code.

The first two patches are the outcome when I played with ARCH=ia64 builds,
but not prerequisites for 3/3. Anyway I believe they are nice cleanups
and folded in this patch set.

3/3 is the important one to fix the false positive warning,
and it is a nice cleanup too.



Masahiro Yamada (3):
  ia64: do not typedef struct pal_min_state_area_s
  ia64: remove unneeded header includes from <asm/mca.h>
  ia64: remove generated/nr-irqs.h generation to fix build warning
