Dave,

Sorry for being late. The patch fixes the issue on the latest git for
PPC64. Infact, the whole drivers/usb/host/ builds just fine:

linux-2.6 # make drivers/usb/host/
  CHK     include/linux/version.h
  CHK     include/linux/utsrelease.h
  SYMLINK include/asm -> include/asm-powerpc
  CALL    scripts/checksyscalls.sh
  CC      drivers/usb/host/ohci-hcd.o
  CC      drivers/usb/host/pci-quirks.o
  CC      drivers/usb/host/uhci-hcd.o
  LD      drivers/usb/host/built-in.o
  CC [M]  drivers/usb/host/isp116x-hcd.o
  CC [M]  drivers/usb/host/u132-hcd.o

You can check in the patch now.

Regards--
Subrata
