"A small set of fixes for the interrupt subsystem:

Without that the interrupt association is completely wrong.

Pull libnvdimm fixes from Dan Williams:
"A fix for namespace label support for non-Intel NVDIMMs that implement
the ACPI standard label method.
This has apparently never worked and could wait for v5.1. However it
has enough visibility with hardware vendors [1] and distro bug
trackers [2], and low enough risk that I decided it should go in for
-rc4. The other fixups target the new, for v5.0, nvdimm security
functionality. The larger init path fixup closes a memory leak and a
potential userspace lockup due to missed notifications.
[1] https://github.com/pmem/ndctl/issues/78
[2] https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1811785

- Fix error handling for security overwrite (memory leak / userspace
hang condition), and another one-line security cleanup"

Xen-swiotlb hooks into the arm/arm64 arch code through a copy of the DMA
DMA mapping operations stored in the struct device arch data.
Switching arm64 to use the direct calls for the merged DMA direct /
swiotlb code broke this scheme. Replace the indirect calls with
direct-calls in xen-swiotlb as well to fix this problem.

syzbot found that ax25 routes where not properly protected
against concurrent use [1].
In this particular report the bug happened while
copying ax25->digipeat.
Fix this problem by making sure we call ax25_get_route()
while ax25_route_lock is held, so that no modification
could happen while using the route.
The current two ax25_get_route() callers do not sleep,
so this change should be fine.
Once we do that, ax25_get_route() no longer needs to
grab a reference on the found route.

This patch adds the detection and handling of a parity error ("process kill

of any HW access that will lead to device access towards the host while
recovery is in progress.
It also provides the means for the protocol drivers to trigger a recovery
process on their decision.

sync_inodes_sb() can race against cgwb (cgroup writeback) membership
switches and fail to writeback some inodes. For example, if an inode
switches to another wb while sync_inodes_sb() is in progress, the new
wb might not be visible to bdi_split_work_to_wbs() at all or the inode
might jump from a wb which hasn't issued writebacks yet to one which
already has.
This patch adds backing_dev_info->wb_switch_rwsem to synchronize cgwb
switch path against sync_inodes_sb() so that sync_inodes_sb() is
guaranteed to see all the target wbs and inodes can't jump wbs to
escape syncing.

This patch adds generic io{read|write}64[be]{_lo_hi|_hi_lo} macros if
they are not already defined by the architecture. (As they are provided
by the generic iomap library).
The patch also points io{read|write}64[be] to the variant specified by the
header name.
This is because new drivers are encouraged to use ioreadXX, et al instead
of readX[1], et al -- and mixing ioreadXX with readq is pretty ugly.

In order to provide non-atomic functions for io{read|write}64 that will
use readq and writeq when appropriate. We define a number of variants
of these functions in the generic iomap that will do non-atomic
operations on pio but atomic operations on mmio.
These functions are only defined if readq and writeq are defined. If
they are not, then the wrappers that always use non-atomic operations
from include/linux/io-64-nonatomic*.h will be used.

Currently we support only platform data for specifying the interconnect
endpoints. As now the endpoints are hard-coded into the consumer driver
this may lead to complications when a single driver is used by multiple
SoCs, which may have different interconnect topology.
To avoid cluttering the consumer drivers, introduce a translation function
to help us get the board specific interconnect data from device-tree.

This patch introduces a new API to get requirements and configure the
interconnect buses across the entire chipset to fit with the current
demand.
The API is using a consumer/provider-based model, where the providers are
the interconnect buses and the consumers could be various drivers.
The consumers request interconnect resources (path) between endpoints and
set the desired constraints on this data flow path. The providers receive
requests from consumers and aggregate these requests for all master-slave
pairs on that path. Then the providers configure each node along the path
to support a bandwidth that satisfies all bandwidth requests that cross
through that node. The topology could be complicated and multi-tiered and
is SoC specific.

We allow more then 255 binderfs binder devices to be created since there
are workloads that require more than that. If we use __u8 we'll overflow
after 255. So let's use a __u32.
Note that there's no released kernel with binderfs out there so this is
not a regression.

Refactor the RTC "CMOS" NVRAM functions so that they can be used as
arch_nvram_ops methods. Checksumming logic is moved from the misc device
operations to the nvram read/write operations. This makes the misc device
implementation more generic.
This preserves the locking mechanism such that "read if checksum valid"
and "write and update checksum" remain atomic operations.
Some platforms implement byte-range read/write methods which are similar
to file_operations struct methods. Other platforms provide only
byte-at-a-time methods. The former are more efficient but may be
unavailable so fall back on the latter methods when necessary.

The drivers/char/nvram.c module has previously supported only RTC "CMOS"
NVRAM, for which it provides appropriate checksum ioctls. Make these
ioctls optional so the module can be re-used with other kinds of NVRAM.
The ops struct methods that implement the ioctls now return error
codes so that a multi-platform kernel binary can do the right thing when
running on hardware without a suitable NVRAM.

NVRAMs on different platforms and architectures have different attributes
and access methods. E.g. some platforms have byte-at-a-time accessor
functions while others have byte-range accessor functions. Some have
checksum functionality while others do not. By calling ops struct methods
via the common wrapper functions, the nvram module and other drivers can
make use of the available NVRAM functionality in a portable way.

Replace nvram_* functions with static functions in nvram.h. These will
become wrappers for struct nvram_ops method calls.
This patch effectively disables existing NVRAM functionality so as to
allow the rest of the series to be bisected without build failures.
That functionality is gradually re-implemented in subsequent patches.
Replace the sole validate-checksum-and-read-byte sequence with a call to
nvram_read() which will gain the same semantics in subsequent patches.
Remove unused exports.

The following warning:
ACPI0012:00: security event setup failed: -19
...is meant to capture exceptional failures of sysfs_get_dirent(),
however it will also fail in the common case when security support is
disabled. A few issues:
1/ A dev_warn() report for a common case is too chatty
2/ The setup of this notifier is generic, no need for it to be driven
from the nfit driver, it can exist completely in the core.
3/ If it fails for any reason besides security support being disabled,
that's fatal and should abort DIMM activation. Userspace may hang if
it never gets overwrite notifications.
4/ The dirent needs to be released.
Move the call to the core 'dimm' driver, make it conditional on security
support being active, make it fatal for the exceptional case, add the
missing sysfs_put() at device disable time.

The only guarantee provided by wake_q_add() is that a wakeup will
happen after it, it does _NOT_ guarantee the wakeup will be delayed
until the matching wake_up_q().
If wake_q_add() fails the cmpxchg() a concurrent wakeup is pending and
that can happen at any time after the cmpxchg(). This means we should
not rely on the wakeup happening at wake_q_up(), but should be ready
for wake_q_add() to issue the wakeup.
The delay; if provided (most likely); should only result in more efficient
behaviour.

ASoC: Fixes for v5.0
Quite a big batch of fixes here. There's a couple of things going on,
the main one is that we found some issues with not deferring probe when
we should, causing us to skip some driver initialization. The fixes for
this then in turn exposed some issues with how we were searching for
components which had previously gone unnoticed due to the original
issue.
There's also been the normal driver specific stuff and there's been what
looks like several batches of automated scanning for issues which have
generated quite a large set of smaller fixes for potential crashes and
missed error handling.
