Merge tag 's390-6.6-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 updates from Heiko Carstens:

- Add vfio-ap support to pass-through crypto devices to secure
execution guests

- Add API ordinal 6 support to zcrypt_ep11misc device drive, which is
required to handle key generate and key derive (e.g. secure key to
protected key) correctly

- Add missing secure/has_secure sysfs files for the case where it is
not possible to figure where a system has been booted from. Existing
user space relies on that these files are always present

- Fix DCSS block device driver list corruption, caused by incorrect
error handling

- Convert virt_to_pfn() and pfn_to_virt() from defines to static inline
functions to enforce type checking

- Cleanups, improvements, and minor fixes to the kernel mapping setup

- Fix various virtual vs physical address confusions

- Move pfault code to separate file, since it has nothing to do with
regular fault handling

- Move s390 documentation to Documentation/arch/ like it has been done
for other architectures already

- Add HAVE_FUNCTION_GRAPH_RETVAL support

- Factor out the s390_hypfs filesystem and add a new config option for
it. The filesystem is deprecated and as soon as all users are gone it
can be removed some time in the not so near future

- Remove support for old CEX2 and CEX3 crypto cards from zcrypt device
driver

- Add support for user-defined certificates: receive user-defined
certificates with a diagnose call and provide them via 'cert_store'
keyring to user space

- Couple of other small fixes and improvements all over the place

s390/zcrypt: remove CEX2 and CEX3 device drivers

Remove the legacy device driver code for CEX2 and CEX3 cards.

The last machines which are able to handle CEX2 crypto cards
are z10 EC first available 2008 and z10 BC first available 2009.
The last machines able to handle a CEX3 crypto card are
z196 first available 2010 and z114 first available 2011.

Please note that this does not imply to drop CEX2 and CEX3
support in general. With older kernels on hardware up to the
aforementioned machine models these crypto cards will get
support by IBM.

The removal of the CEX2 and CEX3 device drivers code opens up
some simplifications, for example support for crypto cards
without rng support can be removed also.

architecture-specific stackleak poison function to enable faster
implementation. On s390, the mvc-based implementation helps decrease
typical overhead from a factor of 3 to just 25%

ENTRY() macro and other annotations. Select ARCH_USE_SYM_ANNOTATIONS

- Improve KASLR to also randomize module and special amode31 code base
load addresses

- Rework decompressor memory tracking to support memory holes and
improve error handling

s390/zcrypt: rework length information for dqap

The inline ap_dqap function does not return the number of
bytes actually written into the message buffer. The calling
code inspects the AP message header to figure out what kind
of AP message has been received and pulls the length
information from this header. This processing may not work
correctly in cases where only a fragment of the reply is
received.

With this patch the ap_dqap inline function now returns
the number of actually written bytes in the *length parameter.
So the calling function has a chance to compare the number of
received bytes against what the AP message header length
field states. This is especially useful in cases where a
message could only get partially received.

The low level reply processing functions needed some rework
to be able to catch this new length information and compare
it the right way. The rework also deals with some situations
where until now the reply length was not correctly calculated
and/or set.

All this has been heavily tested as the modifications on
the reply length information may affect crypto load.
