Video For Linux on ppc32 in kernel 2.6

CONFIG_VIDEO_DEV triggers CONFIG_VIDEO_BUF. If compiled as module,
video-buf.c wants clear_user_page(). This is a define on most archs
(maps to clear_page()), on ppc32 it is an unexported function. This
leads to unresolved symbols.

Should clear_user_page() be exported or should
drivers/media/video/video-buf.c:videobuf_vm_nopage() do something else
to achive similar results?

It's been fixed in BenH's tree since a few weeks.

Yup, hopefully, if I don't forget, I'll get that in 2.6.3
