[PATCH] x86/cpu: Include missing header

[PATCH] x86/cpu: Include missing header

[Luciano Leão]

Include the header containing the prototype of a global function,
solving the following warning:

 arch/x86/kernel/cpu/feat_ctl.c:112:6: warning: no previous prototype for
 'init_ia32_feat_ctl'
 [-Wmissing-prototypes]

This warning appeared after commit 5d5103595e9e5 ("x86/cpu: Reinitialize
IA32_FEAT_CTL MSR on BSP during wakeup") had moved 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, header "cpu.h"
(arch/x86/kernel/cpu/cpu.h) was added by commit 0e79ad863df43 ("x86/cpu:
Fix a -Wmissing-prototypes warning for init_ia32_feat_ctl()")
solely to fix init_ia32_feat_ctl()'s missing prototype. So, header
"cpu.h" is no longer necessary.

x86/cpu: Include the header of init_ia32_feat_ctl()'s prototype

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 commit

  5d5103595e9e5 ("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 commit

  0e79ad863df43 ("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.
