This should be matched by a closing __FINIT. Also, add an explicit ".text" to ensure subsequent code is placed into the correct section; __FINIT is simply a closing marker to match __INIT and doesn't guarantee to revert to .text. This historically caused no problem, because macro __CPUINIT was used at the exact location where __FINIT was missing, which then placed following code into the cpuinit section. However, with commit 22f0a2736 "init.h: remove __cpuinit sections from the kernel" applied, __CPUINIT becomes a no-op, thus leaving all this code in the init section, rather than the regular text section. This caused issues such as secondary CPU boot failures or crashes.
