Commit 003b5c5719f159f4f4bf97511c4702a0638313dd ("block: Convert drivers
to immutable biovecs") incorrectly converted biovec iteration in
dm-verity to always calculate the hash from a full biovec, but the
function only needs to calculate the hash from part of the biovec (up to
the calculated "todo" value).
Fix this issue by limiting hash input to only the requested data size.
This problem was identified using the cryptsetup regression test for
veritysetup (verity-compat-test).

Commit 198d208df4371734ac4728f69cb585c284d20a15 ("x86: Keep
thread_info on thread stack in x86_32") made 32-bit kernels use
kernel_stack to point to thread_info. That change missed a couple of
updates needed by Xen's 32-bit PV guests:
1. kernel_stack needs to be initialized for secondary CPUs
2. GET_THREAD_INFO() now uses %fs register which may not be the
kernel's version when executing xen_iret().
With respect to the second issue, we don't need GET_THREAD_INFO()
anymore: we used it as an intermediate step to get to per_cpu xen_vcpu
and avoid referencing %fs. Now that we are going to use %fs anyway we
may as well go directly to xen_vcpu.

With the recent primary-plane changes for drm, the primary plane's
framebuffer needs to be ref counted the same way as for
non-primary-planes. This was not done by the omapdrm driver, which
caused the ref count to drop to 0 too early, causing problems.
This patch moves the fb unref and ref from omap_plane_update to
omap_plane_mode_set. This way the fb refs are updated for both primary
and non-primary cases, as omap_plane_update calls omap_plane_mode_set.

omap_crtc->old_fb is used to check whether the previous page flip has completed
or not. However, it's never initialized to anything, so it's always NULL. This
results in the check to always succeed, and the page_flip to proceed.
Initialize old_fb to the fb that we intend to flip to through page_flip, and
therefore prevent a future page flip to proceed if the last one didn't
complete.

A waiter of the type OMAP_GEM_READ should wait for a buffer to be completely
written, and only then proceed with reading it. A similar logic applies for
waiters with OMAP_GEM_WRITE flag.
Currently the function is_waiting() waits on the read_complete/read_target
counts in the sync object.
This should be the other way round, as a reader should wait for users who are
'writing' to this buffer, and vice versa.
Make readers of the buffer(OMAP_GEM_READ) wait on the write counters, and
writers to the buffer(OMAP_GEM_WRITE) wait on the read counters in is_waiting()

Patch dfe96ddcfa22b44100814b9435770f6ff1309d37 (omapdrm: simplify locking in

to dump fb objects.
However, in omap_gem_describe we give a WARN is the lock has not been
taken, so that WARN is now seen every time omapdrm debugfs is used.
So, presuming the removal of locks is ok, we can also remove the WARN.

A fl->fl_break_time of 0 has a special meaning to the lease break code
that basically means "never break the lease". knfsd uses this to ensure
that leases don't disappear out from under it.
Unfortunately, the code in __break_lease can end up passing this value
to wait_event_interruptible as a timeout, which prevents it from going
to sleep at all. This makes __break_lease to spin in a tight loop and
causes soft lockups.
Fix this by ensuring that we pass a minimum value of 1 as a timeout
instead.

Commit "59ce0515cdaf iommu/vt-d: Update DRHD/RMRR/ATSR device scope
caches when PCI hotplug happens" introduces a bug, which fails to
match PCI devices with DMAR device scope entries if PCI path array
in the entry has more than one level.
For example, it fails to handle
[1D2h 0466 1] Device Scope Entry Type : 01
[1D3h 0467 1] Entry Length : 0A
[1D4h 0468 2] Reserved : 0000
[1D6h 0470 1] Enumeration ID : 00
[1D7h 0471 1] PCI Bus Number : 00
[1D8h 0472 2] PCI Path : 1C,04
[1DAh 0474 2] PCI Path : 00,02
And cause DMA failure on HP DL980 as:
DMAR:[fault reason 02] Present bit in context entry is clear
dmar: DRHD: handling fault status reg 602
dmar: DMAR:[DMA Read] Request device [02:00.2] fault addr 7f61e000

Commit 146922ec79 ("iommu/vt-d: Make get_domain_for_dev() take struct
device") introduced new variables bridge_bus and bridge_devfn to
identify the upstream PCIe to PCI bridge responsible for the given
target device. Leaving the original bus/devfn variables to identify
the target device itself, now that it is no longer assumed to be PCI
and we can no longer trivially find that information.
However, the patch failed to correctly use the new variables in all
cases; instead using the as-yet-uninitialised 'bus' and 'devfn'
variables.

Since we have csma support this can make some trouble on state changes.

smp_read_barrier_depends() can be used if there is data dependency between
the readers - i.e. if the read operation after the barrier uses address
that was obtained from the read operation before the barrier.
In this file, there is only control dependency, no data dependecy, so the
use of smp_read_barrier_depends() is incorrect. The code could fail in the
following way:
* the cpu predicts that idx < entries is true and starts executing the
body of the for loop
* the cpu fetches map->extent[0].first and map->extent[0].count
* the cpu fetches map->nr_extents
* the cpu verifies that idx < extents is true, so it commits the
instructions in the body of the for loop
The problem is that in this scenario, the cpu read map->extent[0].first
and map->nr_extents in the wrong order. We need a full read memory barrier
to prevent it.

Pablo Neira Ayuso says:
====================
Netfilter fixes for net
The following patchset contains three Netfilter fixes for your net tree,
they are:
* Fix missing generation sequence initialization which results in a splat
if lockdep is enabled, it was introduced in the recent works to improve
nf_conntrack scalability, from Andrey Vagin.
* Don't flush the GRE keymap list in nf_conntrack when the pptp helper is
disabled otherwise this crashes due to a double release, from Andrey
Vagin.
* Fix nf_tables cmp fast in big endian, from Patrick McHardy.

Sometimes, when the packet arrives at skb_mac_gso_segment()
its skb->mac_len already accounts for some of the mac lenght
headers in the packet. This seems to happen when forwarding
through and OpenSSL tunnel.
When we start looking for any vlan headers in skb_network_protocol()
we seem to ignore any of the already known mac headers and start
with an ETH_HLEN. This results in an incorrect offset, dropped
TSO frames and general slowness of the connection.
We can start counting from the known skb->mac_len
and return at least that much if all mac level headers
are known and accounted for.
Fixes: 53d6471cef17262d3ad1c7ce8982a234244f68ec (net: Account for all vlan headers in skb_mac_gso_segment)

Fix typo of renesas,groups in the koeslch dt. The kernel has no
renesas,gpios but this should match renesas,groups.
Noticed thanks to similar fix for Lager by Rob Taylor and Ben Dooks.

This is likely a copy-and-paste error from the
ARM GIC documentation, that has already been fixed.
address-cells should have been set to 0, as with the size
cells. As having those properties set to 0 is the
same thing as not specifying them, drop them completely.

The emulation for single and double precision multiply accumulate
instructions correctly normalised any denormal values in the operand
registers, but failed to normalise the destination (accumulator)
register.
