[PATCH] arch/x86/kernel/cpu/common.c - add proper prototypes

[Valdis KlÄtnieks]

When building withW=1, we get a warning..

  CC      arch/x86/kernel/cpu/common.o
arch/x86/kernel/cpu/common.c:1952:6: warning: no previous prototype for 'arch_smt_update' [-Wmissing-prototypes]
 1952 | void arch_smt_update(void)
      |      ^~~~~~~~~~~~~~~

Provide the proper #include so the prototype is found.
