The 0day build system flags implicit includes as errors. A patch from
Matan Barak to allow hns_roce, an aarch64 specific RDMA driver, to be
built on other arches, but it resulted in build regressions. The
problem is that hns_roce_device.h needs a definition for __raw_writeq
but did not have an include to provide it. Add <linux/io.h> as an
include to resolve the issue.

Pull device mapper fixes from Mike Snitzer:
- a few DM integrity fixes that improve performance. One that address
inefficiencies in the on-disk journal device layout. Another that
makes use of the block layer's on-stack plugging when writing the
journal.

the merge window.
- a few DM raid fixes that address correctness when suspending the
device and a validation fix for validation that occurs during device

use GFP_KERNEL in the IO path due to concerns about deadlock in

Meson8b has to define it's own compatible string for the watchdog. This
patch removes the duplicate resource (register region and interrupt)
definition from meson8b.dtsi and simply re-uses these values from
meson.dtsi (as the register offset, size and interrupt are identical).
This is purely cosmetic and does not change any functionality.

In commit f8f4aaead5 ("perf annotate: Finally display IPC and cycle
accounting") the 'pcnt_width' variable was abused in a few places to
also include the optional width of the "IPC" and "cycles" columns, while
in other places we stopped using 'pcnt_width' and instead its previous
equation...
Now that we need to tap into annotate_browser__pcnt_width() to consider
if --show-total-period is being used and instead of that hardcoded 7
(strlen("Percent")) we need to use it or strlen("Event count") we need
this properly clarified to avoid having to touch all the (7 * nr_events)
places.
Clarify this by introducing a separate annotate_browser__cycles_width()
to leave the pcnt_width calculate just what its name implies.

There is an underlying assumption/trade-off in many layers of the Linux
system that CPU <-> node mapping is static. This is despite the presence
of features like NUMA and 'hotplug' that support the dynamic addition/
removal of fundamental system resources like CPUs and memory. PowerPC
systems, however, do provide extensive features for the dynamic change
of resources available to a system.
Currently, there is little or no synchronization protection around the
updating of the CPU <-> node mapping, and the export/update of this
information for other layers / modules. In systems which can change
this mapping during 'hotplug', like PowerPC, the information is changing
underneath all layers that might reference it.
This patch attempts to ensure that a valid, usable cpumask attribute
is used by the workqueue infrastructure when setting up new resource
pools. It prevents a crash that has been observed when an 'empty'
cpumask is passed along to the worker/task scheduling code. It is
intended as a temporary workaround until a more fundamental review and
correction of the issue can be done.
