CVS commit: src/sys/arch/arm/include

Module Name:    src
Committed By:   chris
Date:           Sun Feb 24 14:00:04 UTC 2008

Modified Files:
        src/sys/arch/arm/include: cpufunc.h

Log Message:
Micro-optimizations for arm.

Make enable and disable interrupts one instruction shorter.

Make cpu_cpwait() do nothing on anything other than an xscale, where it
will still call via the cpufuncs table.

This avoids loading a function from cpufuncs and then branching into it. On
older hardware the function does nothing, so this is just a waste of CPU
