Hey Sam, thanks for your feedback. As per Geert's suggestion, submitted a v2: https://lore.kernel.org/linux-riscv/20220825205942.1713914-1-mail@xxxxxxxxxxx/T/#u In v2, I included linux/processor.h instead of an asm-generic header. The diff for sparc became: diff --git a/arch/sparc/include/asm/cpudata.h b/arch/sparc/include/asm/cpudata.h index d213165ee713..f7e690a7860b 100644 --- a/arch/sparc/include/asm/cpudata.h +++ b/arch/sparc/include/asm/cpudata.h @@ -7,8 +7,6 @@ #include <linux/threads.h> #include <linux/percpu.h> -extern const struct seq_operations cpuinfo_op; - #endif /* !(__ASSEMBLY__) */ #if defined(__sparc__) && defined(__arch64__) diff --git a/arch/sparc/kernel/cpu.c b/arch/sparc/kernel/cpu.c index 79cd6ccfeac0..ffdc7a825b80 100644 --- a/arch/sparc/kernel/cpu.c +++ b/arch/sparc/kernel/cpu.c @@ -12,6 +12,7 @@ #include <linux/smp.h> #include <linux/threads.h> #include <linux/pgtable.h> +#include <linux/processor.h> #include <asm/spitfire.h> #include <asm/oplib.h> Hopefully that is more appealing to you! Thanks, Conor.
