[ Upstream commit 04f5bda84b0712d6f172556a7e8dca9ded5e73b9 ]
When building with W=1, warnings about missing prototypes are emitted:
CC arch/x86/lib/cpu.o
arch/x86/lib/cpu.c:5:14: warning: no previous prototype for 'x86_family' [-Wmissing-prototypes]
5 | unsigned int x86_family(unsigned int sig)
| ^~~~~~~~~~
arch/x86/lib/cpu.c:18:14: warning: no previous prototype for 'x86_model' [-Wmissing-prototypes]
18 | unsigned int x86_model(unsigned int sig)
| ^~~~~~~~~
arch/x86/lib/cpu.c:33:14: warning: no previous prototype for 'x86_stepping' [-Wmissing-prototypes]
33 | unsigned int x86_stepping(unsigned int sig)
| ^~~~~~~~~~~~
Add the proper include file so the prototypes are there.
