Thomas Gleixner f33bc55c47 [PATCH] x86_64: avoid sending LOCAL_TIMER_VECTOR IPI to itself 
Ray Lee reported, that on an UP kernel with "noapic" command line option
set, the box locks hard during boot.

Adding some debug printks revealed, that the last action on the box
before stalling was "Send IPI" - a debug printk which was put into
smp_send_timer_broadcast_ipi().

It seems that send_IPI_mask(mask, LOCAL_TIMER_VECTOR) fails when
"noapic" is set on the command line on an UP kernel.

Aside of that it does not make much sense to trigger an interrupt
instead of calling the function directly on the CPU which gets the
PIT/HPET interrupt in case of broadcasting.
