Yep, and pae should use these as well.  I've changed a few
places with

        #if CONFIG_PAGING_LEVELS >= 4
        #include <asm/shadow_64.h>
        #endif

to "CONFIG_PAGING_LEVELS >= 3", maybe I forgot to include some
into the patch ...

Yep, no actual code changes for PAE yet, that patch was just the
switchover from the old (shadow32.c) to the new shadow code.
PAE will use the 64bit code as the page table entries 64bit wide
as well.

PS: right now the build fails with "public/acm_ops.h: No such
    file or directory" ...

panic("it works"); /* avoid being flooded with debug messages */
