Hi all, After merging the tip tree, today's linux-next build (x86_64 allnoconfig) failed like this: In file included from include/linux/mem_encrypt.h:17, from arch/x86/include/asm/page_types.h:7, from arch/x86/include/asm/page.h:9, from arch/x86/include/asm/thread_info.h:12, from include/linux/thread_info.h:60, from arch/x86/include/asm/preempt.h:9, from include/linux/preempt.h:78, from include/linux/spinlock.h:56, from include/linux/swait.h:7, from include/linux/completion.h:12, from include/linux/crypto.h:15, from arch/x86/kernel/asm-offsets.c:9: arch/x86/include/asm/mem_encrypt.h:23:20: error: static declaration of 'mem_encrypt_init' follows non-static declaration 23 | static inline void mem_encrypt_init(void) { } | ^~~~~~~~~~~~~~~~ In file included from include/linux/printk.h:6, from include/linux/kernel.h:30, from arch/x86/include/asm/percpu.h:27, from arch/x86/include/asm/preempt.h:6: include/linux/init.h:158:6: note: previous declaration of 'mem_encrypt_init' with type 'void(void)' 158 | void mem_encrypt_init(void); | ^~~~~~~~~~~~~~~~ Caused by commits 439e17576eb4 ("init, x86: Move mem_encrypt_init() into arch_cpu_finalize_init()") 0a9567ac5e6a ("x86/mem_encrypt: Unbreak the AMD_MEM_ENCRYPT=n build") from the tip tree interacting with commit ad1a48301f65 ("init: consolidate prototypes in linux/init.h") From the mm tree. I have applied the following merge fix patch for today (but I think it can be consolidated into the mm tree commit - along with removing the parts that remove this declaration from elsewhere).
