commit 5ec164fd61bd8fc7adfb1ca2907d9159eeb1e37b

    x86/boot: re-arrange how/when we do disk I/O
    
    We place the trampoline no lower than at 256k, so we have ample space
    to read the MBRs of BIOS disks into an aligned buffer right below the
    trampoline (not doing so has been found to be a problem on a buggy BIOS
    coming with a Skull Canyon NUC). To facilitate that move MBR reading
    past EDD info retrieval.
    
    Also add a wrap check to the EDD info retrieval loop, to match that in
    the MBR reading one.

    domctl: improve device assignment structure layout and use
    
    Avoid needless gaps. Make flags field mandatory for all three
    operations (and rename it to fit the intended future purpose of
    possibly holding more than just one flag).
    
    Also correct a typo in a related domctl.h comment.

    x86: limit page type width
    
    There's no reason to burn 4 bits on page type when we only have 7 types
    (plus "none") at present. This requires changing one use of
    PGT_shared_page, which so far assumed that the type is both a power of
    2 and the only type with the high bit set.

    x86/HAP: avoid using bogus/misleading locking
    
    hap_teardown() unconditionally releases the paging lock and is always
    being called without the lock held: Lock acquire should then be
    unconditional too.
