KVM: LAPIC: Fix lapic_timer_advance_ns parameter overflow
After commit c3941d9e0 (KVM: lapic: Allow user to disable adaptive tuning of
timer advancement), '-1' enables adaptive tuning starting from default
advancment of 1000ns. However, we should expose an int instead of an overflow
uint module parameter.
Before patch:
/sys/module/kvm/parameters/lapic_timer_advance_ns:4294967295
After patch:
/sys/module/kvm/parameters/lapic_timer_advance_ns:-1
Fixes: c3941d9e0 (KVM: lapic: Allow user to disable adaptive tuning of timer advancement)
