Now that the SST/Skylake driver supports per platform selectors, we
can add logic to automatically select the right driver.
If the Skylake driver is selected for a specific platform, and the DSP
is detected at run-time based on the PCI class/subclass/prog-if
information, the legacy HDaudio driver aborts the probe. This will
result in a single driver probing and remove the need for modprobe
blacklists.
Follow-up patches will add a module parameter to bypass the logic if
this automatic detection fails, or if the Skylake driver is unable to
actually support the platform (firmware authentication, missing
topology file, hardware issue, etc).
The same mechanism will be used to conflicts generated by the same PCI
ID being registered by both legacy HDAuudio and SOF drivers for Intel
platforms. In other words SOF will not require changes to the HDaudio
legacy.

The SOF implementation does not rely on the hdac_bus library, however
for HDMI and HDaudio codec support it does need to deal with
unsolicited events. Instead of re-inventing the wheel, export this
symbol to reuse this part of the library directly.

Not much work on the core this time around but we've seen quite a bit of

with some active development there:
- Preparatory work from Morimoto-san for merging the audio-graph and
audio-graph-scu cards.
- A merge of the TI OMAP and DaVinci directories, the OMAP product line
has been merged into the DaVinci product line so there is now a lot
of IP sharing which meant that the split directories just got in the

There is already inter dependency between the two directories becasue of

With the upcoming AM654 we will need to introduce new platform driver for

With the move I have restructured the Kconfig to be more usable in the era

driver they can be served with.

This commit adds a functionality to multiplex PCM frames into isochronous
packets and demultiplex PCM frames from isochronous packets for ALSA PCM
applications.
Fireface 800 voluntarily maintains resources for tx isochronous
communication. It performs reservation of isochronous channel and
allocation/update of bandwidth in some cases below:
- at a first request to allocation after bus resets
- at requests to allocation when further bandwidth is required
When request is grant and the unit is prepared, read data from
0x0000801c0008 represents isochronous channel for tx stream, then
the unit can handle requests to start communication. If driver
send the request without checking the register, the unit takes
panic to continue bus resets. The unit starts transmission of
tx packets after receiving several rx packets from driver.
I note that the unit can process tx/rx packets and generate/record
sound regardless of HOST LED.

checkstack.pl: fix for aarch64
userfaultfd: check VM_MAYWRITE was set after verifying the uffd is registered
fs/iomap.c: get/put the page in iomap_page_create/release()

mm/sparse: add common helper to mark all memblocks present
mm: introduce common STRUCT_PAGE_MAX_SHIFT define
alpha: fix hang caused by the bootmem removal
The spdxcheck script currently falls over when confronted with a binary
file (such as Documentation/logo.gif). To avoid that, always open files
in binary mode and decode line-by-line, ignoring encoding errors.
One tricky case is when piping data into the script and reading it from
standard input. By default, standard input will be opened in text mode,
so we need to reopen it in binary mode.
The breakage only happens with python3 and results in a
UnicodeDecodeError (according to Uwe).

Right now, checkstack.pl isn't able to print anything on aarch64,
because it won't be able to match the stating objdump line of a function
due to this missing space. Hence, it displays every stack as zero-size.

migrate_page_move_mapping() expects pages with private data set to have
a page_count elevated by 1. This is what used to happen for xfs through
the buffer_heads code before the switch to iomap in commit 82cb14175e
("xfs: add support for sub-pagesize writeback without buffer_heads").
Not having the count elevated causes move_pages() to fail on memory
mapped files coming from xfs.
Make iomap compatible with the migrate_page_move_mapping() assumption by
elevating the page count as part of iomap_page_create() and lowering it
in iomap_page_release().
It causes the move_pages() syscall to misbehave on memory mapped files
from xfs. It does not not move any pages, which I suppose is "just" a
perf issue, but it also ends up returning a positive number which is out
of spec for the syscall. Talking to Michal Hocko, it sounds like
returning positive numbers might be a necessary update to move_pages()
anyway though
(https://lkml.kernel.org/r/20181116114955.GJ14706@dhcp22.suse.cz).
I only hit this in tests that verify that move_pages() actually moved
the pages. The test also got confused by the positive return from
move_pages() (it got treated as a success as positive numbers were not
expected and not handled) making it a bit harder to track down what's
going on.

The conversion of alpha to memblock as the early memory manager caused
boot to hang as described at [1].
The issue is caused because for CONFIG_DISCTONTIGMEM=y case,
memblock_add() is called using memory start PFN that had been rounded
down to the nearest 8Mb and it caused memblock to see more memory that
is actually present in the system.
Besides, memblock allocates memory from high addresses while bootmem was
using low memory, which broke the assumption that early allocations are
always accessible by the hardware.
This patch ensures that memblock_add() is using the correct PFN for the
memory start and forces memblock to use bottom-up allocations.

- spectre indexing fix for aio (Jeff)
- fix for the previous zeroing bio fix, we don't need it for user
mapped pages, and in fact it breaks some applications if we do
(Keith)
- allocation failure fix for null_blk with zoned (Shin'ichiro)"

It specified the wrong parent for a PLL so a part of the clk tree wasn't
rooted correctly. This fixes it by using the right name.

* tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux:
arm64: dma-mapping: Fix FORCE_CONTIGUOUS buffer clearing
One notable fix for our change to split pt_regs between user/kernel, we forgot
to update BPF to use the user-visible type which was an ABI break for BPF
programs.
A slightly ugly but minimal fix to do_syscall_trace_enter() so that we use
tracehook_report_syscall_entry() properly. We'll rework the code in next to
avoid the empty if body.
Seven commits fixing bugs in the new papr_scm (Storage Class Memory) driver.
The driver was finally able to be tested on the other hypervisor which exposed
several bugs. The fixes are all fairly minimal at least.
Fix a crash in our MSI code if an MSI-capable device is plugged into a non-MSI
capable PHB, only seen on older hardware (MPC8378).
Fix our legacy serial code to look for "stdout-path" since the device trees were
updated to use that instead of "linux,stdout-path".
A change to the COFF zImage code to fix booting old powermacs.
A couple of minor build fixes.

Pull drm fixes from Dave Airlie:
"While I hoped things would calm down, the world hasn't joined with me,
but it's a few things scattered over a wide area. The i915 workarounds
regression fix is probably the largest, the rest are more usual sized.
We also get some new AMD PCI IDs.
There is also a patch in here to MAINTAINERS to added Daniel as an
official DRM toplevel co-maintainer, he's decided he wants to step up
and share the glory, and he'll likely process next weeks fixes while
I'm away on holidays.
Summary:
amdgpu:
- some new PCI IDs
- fixed firmware image updates
- power management fixes
- locking warning fix
nouveau:
- framebuffer flushing fix
- memory leak fix
- tegra device init regression fix
vmwgfx:
- OOM kernel memory fix
- excess return in function fix
i915:
- the biggest fix is a regression fix where workarounds weren't
getting reapplied after a gpu hang causing further crashing, this
fixes the workaround application to make it happen again
- GPU hang fixes for Braswell and some GEN3 GPUs
- GVT fix for broadwell tiling
rockchip:
- revert to fix a regression causing a WARN on shutdown
mediatek:
- avoid crash attaching to non-existant bridges"
