Module Name:    src
Committed By:   thorpej

Modified Files:
        src/sys/arch/arm/arm32: bus_dma.c
        src/sys/arch/x86/x86: bus_dma.c

Log Message:
Use cached physical addresses for mbufs and clusters to save having
to extract the physical address from the virtual.

On the ARM, also use the "read-only at MMU" indication to avoid a
redundant cache clean operation.

Other platforms should use these two as examples of how to use these
new pool/mbuf features to improve network performance.  Note this requires
a platform to provide a working POOL_VTOPHYS().

Part 3 in a series of simple patches contributed by Wasabi Systems
to improve network performance.
