Impact: fix sparse build warning Fix the following sparse warnings: arch/x86/kernel/cpu/hypervisor.c:37:15: warning: symbol 'get_hypervisor_tsc_freq' was not declared. Should it be static? arch/x86/kernel/cpu/hypervisor.c:53:16: warning: symbol 'init_hypervisor' was not declared. Should it be static?
