Masahiro Yamada fa1e160b08 ia64: remove generated/nr-irqs.h generation to fix build warning ... Randy reports the following warning when building ARCH=ia64 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 message is actually false-positive, and you can get palinfo.ko correctly built. It is emitted in the archprepare stage, where Kbuild descends into arch/ia64/kernel to generate include/generated/nr-irqs.h instead of any kind of kernel objects. arch/ia64/kernel/nr-irqs.c was introduced by commit 213060a4d6 ("[IA64] pvops: paravirtualize NR_IRQS") to pre-calculate: NR_IRQS = max(IA64_NATIVE_NR_IRQS, XEN_NR_IRQS, FOO_NR_IRQS...) Since commit d52eefb47d ("ia64/xen: Remove Xen support for ia64"), this union contains just one field, making NR_IRQS and IA64_NATIVE_NR_IRQS always match. So, the following hard-coding now works: #define NR_IRQS IA64_NATIVE_NR_IRQS If you need to re-introduce NR_IRQS = max(...) gimmick in the future, please try to implement it in asm-offsets.c instead of a separate file. It will be possible because the header inclusion has been consolidated to make asm-offsets.c independent of <asm/irqs.h>.
