Module Name:    src
Committed By:   joerg

Modified Files:
        src/sys/arch/amd64/include: cpu.h
        src/sys/arch/i386/include: cpu.h
        src/sys/arch/x86/x86: lapic.c

Log Message:
Add a CPU local timer based on the LAPIC. This is consistently faster
than TSC, but doesn't suffer from SpeedStep as TSC does.

The default quality is higher than HPET for UP, but -100 for
MULTIPROCESSOR as it needs CPU local state which doesn't exist yet.
