    s390/zcrypt: Support up to 256 crypto adapters. · af4a7227
    Harald Freudenberger authored
    There was an artificial restriction on the card/adapter id
    to only 6 bits but all the AP commands do support adapter
    ids with 8 bit. This patch removes this restriction to 64
    adapters and now up to 256 adapter can get addressed.
    
    Some of the ioctl calls work on the max number of cards
    possible (which was 64). These ioctls are now deprecated
    but still supported. All the defines, structs and ioctl
    interface declarations have been kept for compabibility.
    There are now new ioctls (and defines for these) with an
    additional '2' appended which provide the extended versions
    with 256 cards supported.
