    dri2: Register the DRI2DrawableType after server regeneration
    
    The Resource database is reset upon regeneration and so the dri2 module
    needs to re-register its RESTYPE for the drawable or else it will
    clobber the next unsuspecting user of the database. Fortunately, DRI2 is
    loaded late in the initialisation sequence and was last up until
    xf86-video-intel started using the Resource database to track
    outstanding swaps...

    record: Prevent out of bounds access when recording a reply.
    
    Any pad bytes in replies are written to the client from a zeroed
    array. However, record extension tries to incorrectly access the pad
    bytes from the end of reply data.

    xfree86: Fix powerpc build with -Werror=int-to-pointer-cast -Werror=pointer-to-int-cast
    
    memType is a uint64_t on powerpc. Using memType only really makes
    sense for *physical* addresses, which can be 64-bit for 32-bit
    systems running on 64-bit hardware.
    
    However, unmapVidMem() only deals with *virtual* addresses, which
    are guaranteed to fit into an uintptr_t.
