Try copying drivers/block/flash-mem.h from the handhelds.org tree over the
one in my patch.

Take a fresh 2.4.0-test9 tree and copy drivers/usb/usb-net-host.c from
the patched tree to the unpatched one. Next edit drivers/usb/Config.in
and drivers/usb/Makefile to add the single line dealing with
CONFIG_USB_NET_HOST to reflect the patched tree. Then you should be able
to build yourself a 2.4.0-test9 tree with usb-net-host module for your PC.
