2af48080e1 [S390] zcrypt: fix PCIXCC/CEX2C error recovery 
Symptom:     zcrypt fails by setting all PCIXCC/CEX2C cards offline for a
             certain type of invalid keys.
Problem:     zcrypt does not handle rc=12/rs=769 request responses correctly
Solution:    modify convert_type86_ica() to handle these error codes correctly

af512ed0f8 [S390] zcrypt: fix request timeout handling 
Under very high load zcrypt requests may timeout while waiting on the
request queue. Modify zcrypt that timeouts are based on crypto adapter
responses. A timeout occurs only if a crypto adapter does not respond
within a given time frame to sumitted requests.

5cbded585d [PATCH] getting rid of all casts of k[cmz]alloc() calls 
Run this:

	#!/bin/sh
	for f in $(grep -Erl "\([^\)]*\) *k[cmz]alloc" *) ; do
	  echo "De-casting $f..."
	  perl -pi -e "s/ ?= ?\([^\)]*\) *(k[cmz]alloc) *\(/ = \1\(/" $f
	done

And then go through and reinstate those cases where code is casting pointers
to non-pointers.

And then drop a few hunks which conflicted with outstanding work.

5432114baf [S390] zcrypt secure key cryptography extension. 
Allow the user space to send extended cprb messages directly to the
PCIXCC / CEX2C cards. This allows the CCA library to construct special
crypto requests that use "secure" keys that are stored on the card.
