While general idea of patch was good, it was not working properly due the way
it was implemented. When we are using same timer interrupt for several of
hard/prof/stat purposes we should not send several IPIs same time to other
CPUs. Sending several IPIs same time leads to terrible accounting/profiling
results due to strong synchronization effect, when the second interrupt
handler accounts processing of the first one.
Interlink timer events in a such way, that no more then one IPI is sent for
any original timer interrupt.

Evidently FreeBSD has long relied on the compiler to treat structures

atpic.c

Explicitly use spinlock_enter/exit rather than locking the icu_lock spin
