* 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

- avoid crash attaching to non-existant bridges"

With the new validation code, a malicious user-space app could
potentially submit command streams with enough buffer-object and resource
references in them to have the resulting allocated validion nodes and
relocations make the kernel run out of GFP_KERNEL memory.
Protect from this by having the validation code reserve TTM graphics
memory when allocating.

- Fix long-standing race with how DM thinp notified userspace of

- Fix DM cache metadata to verify that a cache has block before trying
to continue with operation that requires them.
- Fix bio-based DM core's dm_make_request() to properly impose device
limits on individual bios by making use of blk_queue_split().
- Fix long-standing race with how DM thinp notified userspace of
thin-pool mode state changes before they were actually made.
- Fix the zoned target's bio completion handling; this is a fairly
invassive fix at this stage but it is localized to the zoned target.
Any zoned target users will benefit from this fix.

lkml and Linus gained a CoC, and it's serious this time. Which means
my no 1 reason for declining to officially step up as drm maintainer
is gone, and I didn't find any new good excuse.
I chatted with a few people in private already, and the biggest
concern is that I mislay my community hat and start running around
with my intel hat only. Or some other convenient abuse of trust.
That's why this patch doesn't just need a lot of acks that mean "yeah
seems fine to me", but a lot of acks that mean "yeah we'll tell you
when you're over the line and usurp you from that comfy chair if you
don't get it". Which I think we've been done a fairly good job here at
dri-devel in general, but better to be clear.
Rough idea is that I'll do this for maybe 2-3 years, helping Dave
figure out a group model for drm overall. And getting the tooling and
infrastructure for that off the ground. Then step down again because
some other shiny thing that needs chasing. Of course as plans tend to
do, this one will probably pan out a bit different in reality.

When support for bonding of RoCE devices was added, there was
necessarily a link between the RoCE device and the paired netdevice that
was part of the bond. If you remove the mlx4_en module, that paired
association is broken (the RoCE device is still present but the paired
netdevice has been released). We need to account for this in
is_upper_ndev_bond_master_filter() and filter out those links with a
broken pairing or else we later oops in netdev_next_upper_dev_rcu().

Currently we allocate a scratch page for each engine, but since we only
ever write into it for post-sync operations, it is not exposed to
userspace nor do we care for coherency. As we then do not care about its
contents, we can use one page for all, reducing our allocations and
avoid complications by not assuming per-engine isolation.
For later use, it simplifies engine initialisation (by removing the
allocation that required struct_mutex!) and means that we can always rely
on there being a scratch page.

Braswell is really picky about having our writes posted to memory before
we execute or else the GPU may see stale values. A wmb() is insufficient
as it only ensures the writes are visible to other cores, we need a full
mb() to ensure the writes are in memory and visible to the GPU.
The most frequent failure in flushing before execution is that we see
stale PTE values and execute the wrong pages.

Commit f149b31557 ("signal: Never allocate siginfo for SIGKILL or SIGSTOP")
means that the seccomp selftest cannot check si_pid under SIGSTOP anymore.
Since it's believed[1] there are no other userspace things depending on the
old behavior, this removes the behavioral check in the selftest, since it's
more a "extra" sanity check (which turns out, maybe, not to have been
useful to test).

Sending a DM event before a thin-pool state change is about to happen is
a bug. It wasn't realized until it became clear that userspace response
to the event raced with the actual state change that the event was
meant to notify about.
Fix this by first updating internal thin-pool state to reflect what the
DM event is being issued about. This fixes a long-standing racey/buggy
userspace device-mapper-test-suite 'resize_io' test that would get an
event but not find the state it was looking for -- so it would just go
on to hang because no other events caused the test to reevaluate the
thin-pool's state.

When create_event_filter() fails in set_trigger_filter(), the filter may
still be allocated and needs to be freed. The caller expects the

failed (we could add an error message by setting set_str parameter of
create_event_filter(), but that's another update).
But because the error would just exit, filter was left hanging and
nothing could free it.

the dual thermal zones definition is not available in the DT yet, so
when the driver tries to register all the sensors that fails.
By reducing to 1 the number of sensors on the hi3660, we switch back
to the previous functionnality.

Without this patch, the thermal driver on hi6220 and hi3660 is broken.
That is due because part of the posted patchset was merged but a small
change in the DT was dropped.
The hi6220 and hi3660 do not have an interrupt name in the DT, so
finding interrupt by name fails.
Fix this by returning back to the platform_get_irq() function call.
