There is no need to busy loop and monopolize a cpu for up to ~2 seconds.
The code in question that calls mdelay() is preemptible anyway, so better
let the kernel schedule different processes than just looping and causing
unnecessary delays.

Msgtype implementations are now separated from card specific modules
and can be dynamically registered. Existing msgtype implementations
are restructured in modules.

<title>s390/comments: unify copyright messages and remove file names</title>

Remove the file name from the comment at top of many files. In most
cases the file name was wrong anyway, so it's rather pointless.

Also unify the IBM copyright statement. We did have a lot of sightly
different statements and wanted to change them one after another
whenever a file gets touched. However that never happened. Instead
people start to take the old/"wrong" statements to use as a template
for new files.
So unify all of them in one go.

<title>[S390] zcrypt: cope with cca restriction of cex3</title>

<id>c2567f8ffa2704f6f2f81013e9a590deca5a865f</id>
<content type='text'>
The cca on the crypto adapter has a restriction in the size of the
exponent if a key with a modulus bigger than 2048 bit is used. Thus
in that case we have to avoid that the crypto device driver thinks
the adapter is defect and sets it offline. Therfore a new member for
the zcrypt_device struct called max_exp_bit_length is introduced. This
will be set the first time the cca returns the error code function
not implemented. If this is done with an adapter twice it will return
-EINVAL.
