#     smpboot: fix duplicate and misplaced inlining directive
#     
#     gcc doesn't care, but clang quite reasonably pointed out that the recent
#     commit e9ba16e68cce ("smpboot: Mark idle_init() as __always_inlined to
#     work around aggressive compiler un-inlining") did some really odd
#     things:
#     
#         kernel/smpboot.c:50:20: warning: duplicate 'inline' declaration specifier [-Wduplicate-decl-specifier]
#         static inline void __always_inline idle_init(unsigned int cpu)
#                            ^
#     
#     which not only has that duplicate inlining specifier, but the new
#     __always_inline was put in the wrong place of the function definition.
#     
#     We put the storage class specifiers (ie things like "static" and
#     "extern") first, and the type information after that.  And while the
#     compiler may not care, we put the inline specifier before the types.
#     
#     So it should be just
#     
#         static __always_inline void idle_init(unsigned int cpu)
#     
#     instead.
