Pull powerpc updates from Michael Ellerman:
 "Highlights include:

   - Support for the kexec_file_load() syscall, which is a prereq for
     secure and trusted boot.

   - Prevent kernel execution of userspace on P9 Radix (similar to
     SMEP/PXN).

   - Sort the exception tables at build time, to save time at boot, and
     store them as relative offsets to save space in the kernel image &
     memory.

   - Allow building the kernel with thin archives, which should allow us
     to build an allyesconfig once some other fixes land.

   - Build fixes to allow us to correctly rebuild when changing the
     kernel endian from big to little or vice versa.

   - Plumbing so that we can avoid doing a full mm TLB flush on P9
     Radix.

   - Initial stack protector support (-fstack-protector).

   - Support for dumping the radix (aka. Linux) and hash page tables via
     debugfs.

   - Fix an oops in cxl coredump generation when cxl_get_fd() is used.

   - Freescale updates from Scott: "Highlights include 8xx hugepage

Pull m ore s390 updates from Martin Schwidefsky:
 "Over 95% of the changes in this pull request are related to the zcrypt
  driver. There are five improvements for zcrypt: the ID for the CEX6
  cards is added, workload balancing and multi-domain support are
  introduced, the debug logs are overhauled and a set of tracepoints is
  added.

  Then there are several patches in regard to inline assemblies. One
  compile fix and several missing memory clobbers. As far as we can tell
  the omitted memory clobbers have not caused any breakage.

  A small change to the PCI arch code, the machine can tells us how big
  the function measurement blocks are. The PCI function measurement will
  be disabled for a device if the queried length is larger than the
  allocated size for these blocks.

  And two more patches to correct five printk messages.

Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

By now, linux is mostly endian-clean. Enabling endian-ness
checks for everyone produces about 200 new sparse warnings for me -
less than 10% over the 2000 sparse warnings already there.

Not a big deal, OTOH enabling this helps people notice
they are introducing new bugs.

So let's just drop __CHECK_ENDIAN__. Follow-up patches
can drop distinction between __bitwise and __bitwise__.

Despite living under drivers/ vringh.c is also used as part of the userspace
virtio tools. Before we can kill off the ACCESS_ONCE()definition in the tools,
we must convert vringh.c to use {READ,WRITE}_ONCE().

This patch does so, along with the required include of <linux/compiler.h> for
the relevant definitions. The userspace tools provide their own definitions in
their own <linux/compiler.h>.

The virtio tools implementation of READ_ONCE() has a single parameter called
'var', but erroneously refers to 'val' for its cast, and thus won't work unless
there's a variable of the correct type that happens to be called 'var'.

Fix this with s/var/val/, making READ_ONCE() work as expected regardless.

This patch introduces virtio-crypto driver for Linux Kernel.

The virtio crypto device is a virtual cryptography device
as well as a kind of virtual hardware accelerator for
virtual machines. The encryption anddecryption requests
are placed in the data queue and are ultimately handled by
thebackend crypto accelerators. The second queue is the
control queue used to create or destroy sessions for
symmetric algorithms and will control some advanced features
in the future. The virtio crypto device provides the following
cryptoservices: CIPHER, MAC, HASH, and AEAD.

For more information about virtio-crypto device, please see:

When event index was enabled, we need to fetch used event from
userspace memory each time. This userspace fetch (with memory
barrier) could be saved sometime when 1) caching used event and 2)
if used event is ahead of new and old to new updating does not cross
it, we're sure there's no need to notify guest.

This will be useful for heavy tx load e.g guest pktgen test with Linux
driver shows ~3.5% improvement.
