CVS commit: src/sys/dev/usb

Module Name:    src
Committed By:   matt

Modified Files:
        src/sys/dev/usb: files.usb usb_mem.c

Log Message:
Add a workaround (hopefully temporary) for corrupted usb fragments on powerpc.
With this in effect, USB is now usable on some powerpc platforms again.
Basically this prevents the DMA portion of the fragment ever overlapping the
usb_frag_hdr which is enough to solve the problem.  To enable this, add

options         USB_FRAG_DMA_WORKAROUND

to your config file.
Switch from malloc to kmem.
