[ Upstream commit30ea703a38] Include the header containing the prototype of init_ia32_feat_ctl(), solving the following warning: $ make W=1 arch/x86/kernel/cpu/feat_ctl.o arch/x86/kernel/cpu/feat_ctl.c:112:6: warning: no previous prototype for ‘init_ia32_feat_ctl’ [-Wmissing-prototypes] 112 | void init_ia32_feat_ctl(struct cpuinfo_x86 *c) This warning appeared after commit5d5103595e("x86/cpu: Reinitialize IA32_FEAT_CTL MSR on BSP during wakeup") had moved the function init_ia32_feat_ctl()'s prototype from arch/x86/kernel/cpu/cpu.h to arch/x86/include/asm/cpu.h. Note that, before the commit mentioned above, the header include "cpu.h" (arch/x86/kernel/cpu/cpu.h) was added by commit0e79ad863d("x86/cpu: Fix a -Wmissing-prototypes warning for init_ia32_feat_ctl()") solely to fix init_ia32_feat_ctl()'s missing prototype. So, the header include "cpu.h" is no longer necessary.
