Subject: [PATCH 3.18 027/120] x86/tsc: Add missing header to tsc_msr.c

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Andy Shevchenko <andriy.shevchenko@...ux.intel.com>

[ 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 ‘cpu_khz_from_msr’ [-Wmissing-prototypes]
   unsigned long cpu_khz_from_msr(void)
                 ^~~~~~~~~~~~~~~~
