All architectures now need ioremap_uc(), ia64 seems defines this already
through its ioremap_nocache() and it already ensures it *only* uses UC.
This is needed since v4.3 to complete an allyesconfig compile on ia64,
there were others archs that needed this, and this one seems to have
fallen through the cracks.

Pull VFIO updates from Alex Williamson:
"Various enablers for assignment of Intel graphics devices and future
support of vGPU devices (Alex Williamson). This includes
- Handling the vfio type1 interface as an API rather than a specific
implementation, allowing multiple type1 providers.
- Capability chains, similar to PCI device capabilities, that allow
extending ioctls. Extensions here include device specific regions
and sparse mmap descriptions. The former is used to expose non-PCI
regions for IGD, including the OpRegion (particularly the Video
BIOS Table), and read only PCI config access to the host and LPC
bridge as drivers often depend on identifying those devices.
Sparse mmaps here are used to describe the MSIx vector table, which
vfio has always protected from mmap, but never had an API to
explicitly define that protection. In future vGPU support this is
expected to allow the description of PCI BARs that may mix direct
access and emulated access within a single region.
- The ability to expose the shadow ROM as an option ROM as IGD use
cases may rely on the ROM even though the physical device does not
make use of a PCI option ROM BAR"

Add a new pseudo-board, within the existing SH boards/machine-vectors
framework, which does not represent any actual hardware but instead
requires all hardware to be described by the device tree blob provided
by the boot loader. Changes made are thus non-invasive and do not risk
breaking support for legacy boards.
New hardware, including the open-hardware J2 and associated SoC
devices, will use device free from the outset. Legacy SH boards can
transition to device tree once all their hardware has device tree
bindings, driver support for device tree, and a dts file for the
board.
It is intented that, once all boards are supported in the new
framework, the existing machine-vectors framework should be removed
and the new device tree setup code integrated directly.

Historically SH-2 Linux (and originally uClinux) used a syscall
calling convention incompatible with the established SH-3/4 Linux ABI.
This choice was made because the trap range used by the existing ABI,
0x10-0x17, overlaps with the hardware exception/interrupt trap range
reserved by SH-2, and in particular, with the SH-2A divide-by-zero and
division-overflow exceptions.
Despite the documented syscall convention using the low bits of the
trap number to signal the number of arguments the kernel should
expect, no version of the kernel has ever used this information, nor
is it useful; all of the registers need to be saved anyway. Therefore,
it is possible to pick a new trap number, 0x1f, that is both supported
by all existing SH-3/4 kernels and unassigned as a hardware trap in
the SH-2 range. This makes it possible to produce SH-2 application
binaries that are forwards-compatible with running on SH-3/4 kernels
and to treat SH as a unified platform with varying ISA support levels
rather than multiple gratuitously-incompatible platforms.
This patch adjusts the range checking SH-2 and SH-2A kernels make for
the syscall trap to accept the range 0x1f-0x2f rather than just
0x20-0x2f. As a result, trap 0x1f now acts as a syscall for all SH
models.

The generic header file is almost equivalent to the SH one. The
only difference is that the SH one supports allocating clkdev
lookups early using bootmem allocators instead of the slabs. From
what I can tell using visual inspection, the slab is initialized
before any clkdev allocation is made under arch/sh. So let's
remove the arch specific clkdev.h header and use the generic one
instead.

The recent change in HD-audio HDMI/DP codec driver for allowing the
dynamic PCM binding introduced a new spec->pcm_mutex. One of the
protected area by this mutex is hdmi_present_sense(). As reported by
Intel CI tests, unfortunately, the new mutex causes a deadlock when
the hotplug/unplug is triggered during the codec is in runtime
suspend. The buggy code path is like the following:
hdmi_unsol_event() -> ...
-> hdmi_present_sense()
==> ** here taking pcm_mutex
-> hdmi_present_sense_via_verbs()
-> snd_hda_power_up_pm() -> ... (runtime resume calls)
-> generic_hdmi_resume()
-> hdmi_present_sense()
==> ** here taking pcm_mutex again!
As we can see here, the problem is that the mutex is taken before
snd_hda_power_up_pm() call that triggers the runtime resume. That is,
the obvious solution is to move the power up/down call outside the
mutex; it is exactly what this patch provides.
The patch also clarifies why this bug wasn't caught beforehand. We
used to have the i915 audio component for hotplug for all Intel chips,
and in that code path, there is no power up required but the
information is taken directly from the graphics side. However, we
recently switched back to the old method for some old Intel chips due
to regressions, and now the deadlock issue is surfaced.
Fixes: a76056f2e57e ('ALSA: hda - hdmi dynamically bind PCM to pin when monitor hotplug')

Remove the livepatch module notifier in favor of directly enabling and
disabling patches to modules in the module loader. Hard-coding the
function calls ensures that ftrace_module_enable() is run before
klp_module_coming() during module load, and that klp_module_going() is
run before ftrace_release_mod() during module unload. This way, ftrace
and livepatch code is run in the correct order during the module
load/unload sequence without dependence on the module notifier call chain.

Put all actions in complete_formation() that are performed after
module->state is set to MODULE_STATE_COMING into a separate function
prepare_coming_module(). This split prepares for the removal of the
livepatch module notifiers in favor of hard-coding function calls to
klp_module_{coming,going} in the module loader.
The complete_formation -> prepare_coming_module split will also make error
handling easier since we can jump to the appropriate error label to do any
module GOING cleanup after all the COMING-actions have completed.

Pull libnvdimm updates from Dan Williams:
- Asynchronous address range scrub:
Given the capacities of next generation persistent memory devices a
scrub operation to find all poison may take 10s of seconds. We
want this scrub work to be done asynchronously with the rest of
system initialization, so we move it out of line from the NFIT
probing, i.e. acpi_nfit_add().
- Clear poison:
ACPI 6.1 introduces the ability to send "clear error" commands to
the ACPI0012:00 device representing the root of an "nvdimm bus".
Similar to relocating a bad block on a disk, this support clears
media errors in response to a write.
- Persistent memory resource tracking:
A persistent memory range may be designated as simply "reserved" by
platform firmware in the efi/e820 memory map. Later when the NFIT
driver loads it discovers that the range is "Persistent Memory".
The NFIT bus driver inserts a resource to advertise that
"persistent" attribute in the system resource tree for /proc/iomem
and kernel-internal usages.
- Miscellaneous cleanups and fixes:
Workaround section misaligned pmem ranges when allocating a struct
page memmap, fix handling of the read-only case in the ioctl path,
and clean up block device major number allocation.

Pull device mapper updates from Mike Snitzer:
- Most attention this cycle went to optimizing blk-mq request-based DM
(dm-mq) that is used exclussively by DM multipath:
- A stable fix for dm-mq that eliminates excessive context
switching offers the biggest performance improvement (for both
IOPs and throughput).
- But more work is needed, during the next cycle, to reduce
spinlock contention in DM multipath on large NUMA systems.
- A stable fix for a NULL pointer seen when DM stats is enabled on a DM
multipath device that must requeue an IO due to path failure.
- A stable fix for DM snapshot to disallow the COW and origin devices
from being identical. This amounts to graceful failure in the face
of userspace error because these devices shouldn't ever be identical.
- Stable fixes for DM cache and DM thin provisioning to address crashes
seen if/when their respective metadata device experiences failures
that cause the transition to 'fail_io' mode.
- The DM cache 'mq' policy is now an alias for the 'smq' policy. The
'smq' policy proved to be consistently better than 'mq'. As such
'mq', with all its complex user-facing tunables, has been eliminated.
- Improve DM thin provisioning to consistently return -ENOSPC once the
thin-pool's data volume is out of space.
- Improve DM core to properly handle error propagation if
bio_integrity_clone() fails in clone_bio().
- Other small cleanups and improvements to DM core.

It is possible, although unlikely, that probing will find the
phy_device for the first LMAC of a thunder BGX device, but then need
to fail with -EPROBE_DEFER on a subsequent LMAC. In this case, we
need to call put_device() on each of the phy_devices that were
obtained, but will be unused due to returning -EPROBE_DEFER.
Also, since we can break out of the probing loop early, we need to
explicitly call of_node_put() outside of the loop.

Locking ppp_mutex must be done before dereferencing file->private_data,
otherwise it could be modified before ppp_unattached_ioctl() takes the
lock. This could lead ppp_unattached_ioctl() to override ->private_data,
thus leaking reference to the ppp_file previously pointed to.
v2: lock all ppp_ioctl() instead of just checking private_data in
ppp_unattached_ioctl(), to avoid ambiguous behaviour.

The emac needs constant and very specific rate but the possible PLL-sources

When the ETHTOOL_GLINKSETTINGS implementation finds that userland is
using the wrong number of words of link mode bitmaps (or is trying to
find out the right numbers) it sets the cmd field to 0 in the response

This is inconsistent with the implementation of every other ethtool
