This resolves a clang warning that I see:
kernel/smpboot.c:50:20: error: duplicate 'inline' declaration specifier [-Werror,-Wduplicate-decl-specifier]
static inline void __always_inline idle_init(unsigned int cpu)
^
./include/linux/compiler_attributes.h:65:41: note: expanded from macro '__always_inline'
#define __always_inline inline __attribute__((__always_inline__))
^
./include/linux/compiler_types.h:149:16: note: expanded from macro 'inline'
#define inline inline __gnu_inline __inline_maybe_unused notrace
^
1 error generated.
