From: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>

[ Upstream commit dbd0fbc76c77daac08ddd245afdcbade0d506e19 ]

Add a missing header otherwise compiler warns about missed prototype:

CC arch/x86/kernel/tsc_msr.o
arch/x86/kernel/tsc_msr.c:73:15: warning: no previous prototype for âcpu_khz_from_msrâ [-Wmissing-prototypes]
unsigned long cpu_khz_from_msr(void)
