History
Konstantin Belousov ecabd74728 Use TSC deadline mode for LAPIC timer, when available. The mode fires 
LAPIC timer iinterrupt when TSC reaches the value written to the
IA32_TSC_DEADLINE MSR.  To arm or reset the timer in deadline mode, a
single non-serializing MSR write is enough.  This is an advance from
the one-shot mode of LAPIC, where timer operated with the FSB
frequency and required two (serialized in case of xAPIC) writes to the
APIC registers.

The LVT_TIMER register value is cached to avoid unneeded writes in the
deadline mode.  Unused arguments to specify period (which is passed in
struct lapic as la_timer_period) and interrupt enable (which is always
enabled) are removed from lapic_timer_{oneshot,periodic,deadline}
functions.  Instead, special lapic_timer_oneshot_nointr() function for
interrupt-less one-shot calibration is added.
