  • This patch reworks filemap_xip.c with the goal to reduce code duplication
    from mm/filemap.c. It applies agains 2.6.12-rc6-mm1. Instead of
    implementing the aio functions, this one implements the synchronous
    read/write functions only. For readv and writev, the generic fallback is
    used. For aio, we rely on the application doing the fallback. Since our
    "synchronous" function does memcpy immediately anyway, there is no
    performance difference between using the fallbacks or implementing each
    operation.

  • - generic_file* file operations do no longer have a xip/non-xip split
    - filemap_xip.c implements a new set of fops that require get_xip_page
    aop to work proper. all new fops are exported GPL-only (don't like to
    see whatever code use those except GPL modules)
    - __xip_unmap now uses page_check_address, which is no longer static
    in rmap.c, and defined in linux/rmap.h
    - mm/filemap.h is now much more clean, plainly having just Linus'
    inline funcs moved here from filemap.c
    - fix includes in filemap_xip to make it build cleanly on i386
