I'm building the video4linux drivers as modules and the video-buf driver
can't load as it has no reference to shm_align_mask and
These are needed by asm-mips/page.h for the inline funcs, pages_do_alias
How should shm_align_mask and flush_data_cache_page. be exported to
Most other asm-xxx/page.h doesn't need any externs, all is #defined
within page.h or files included by it.
Any ideas how I deal with this? Presumably other modules will be
affected by this.
