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.
