What used to be the input_10_bits boolean - feeding into the lowest
bit of DSC_ENC - on MSM downstream turned into an accidental OR with
the full bits_per_component number when it was ported to the upstream
kernel.
On typical bpc=8 setups we don't notice this because line_buf_depth is
always an odd value (it contains bpc+1) and will also set the 4th bit
after left-shifting by 3 (hence this |= bits_per_component is a no-op).
Now that guards are being removed to allow more bits_per_component
values besides 8 (possible since commit 49fd30a7153b ("drm/msm/dsi: use
DRM DSC helpers for DSC setup")), a bpc of 10 will instead clash with
the 5th bit which is convert_rgb. This is "fortunately" also always set
to true by MSM's dsi_populate_dsc_params() already, but once a bpc of 12
starts being used it'll write into simple_422 which is normally false.
To solve all these overlaps, simply replicate downstream code and only
set this lowest bit if bits_per_component is equal to 10. It is unclear
why DSC requires this only for bpc=10 but not bpc=12, and also notice
that this lowest bit wasn't set previously despite having a panel and
patch on the list using it without any mentioned issues.

Disable pingpong dither in dpu_encoder_helper_phys_cleanup().
This avoids the issue where an encoder unknowingly uses dither after

Widebus allows the DP controller to operate in 2 pixel per clock mode.
The mode validation logic validates the mode->clock against the max
DP pixel clock. However the max DP pixel clock limit assumes widebus
is already enabled. Adjust the mode validation logic to only compare
the adjusted pixel clock which accounts for widebus against the max DP
pixel clock. Also fix the mode validation logic for YUV420 modes as in
that case as well, only half the pixel clock is needed.

The pages_touched field represents the number of subbuffers in the ring
buffer that have content that can be read. This is used in accounting of
"dirty_pages" and "buffer_percent" to allow the user to wait for the
buffer to be filled to a certain amount before it reads the buffer in
blocking mode.
The persistent buffer never updated this value so it was set to zero, and
this accounting would take it as it had no content. This would cause user
space to wait for content even though there's enough content in the ring
buffer that satisfies the buffer_percent.

The reason was that the code that maps the ring buffer pages to user space
has:
page = virt_to_page((void *)cpu_buffer->subbuf_ids[s]);
And uses that in:
vm_insert_pages(vma, vma->vm_start, pages, &nr_pages);
But virt_to_page() does not work with vmap()'d memory which is what the
persistent ring buffer has. It is rather trivial to allow this, but for
now just disable mmap() of instances that have their ring buffer from the
reserve_mem option.
If an mmap() is performed on a persistent buffer it will return -ENODEV
just like it would if the .mmap field wasn't defined in the
file_operations structure.

The Tegra210 Audio DMA controller driver did a plain divide:
page_no = (res_page->start - res_base->start) / cdata->ch_base_offset;
which causes problems on 32-bit x86 configurations that have 64-bit
resource sizes:
x86_64-linux-ld: drivers/dma/tegra210-adma.o: in function `tegra_adma_probe':
tegra210-adma.c:(.text+0x1322): undefined reference to `__udivdi3'
because gcc doesn't generate the trivial code for a 64-by-32 divide,
turning it into a function call to do a full 64-by-64 divide. And the
kernel intentionally doesn't provide that helper function, because 99%
of the time all you want is the narrower version.
Of course, tegra210 is a 64-bit architecture and the 32-bit x86 build is
purely for build testing, so this really is just about build coverage
failure.
But build coverage is good.
Side note: div_u64() would be suboptimal if you actually have a 32-bit
resource_t, so our "helper" for divides are admittedly making it harder
than it should be to generate good code for all the possible cases.
At some point, I'll consider 32-bit x86 so entirely legacy that I can't
find it in myself to care any more, and we'll just add the __udivdi3
library function.
But for now, the right thing to do is to use "div_u64()" to show that
you know that you are doing the simpler divide with a 32-bit number.
And the build error enforces that.
While fixing the build issue, also check for division-by-zero, and for
overflow. Which hopefully cannot happen on real production hardware,
but the value of 'ch_base_offset' can definitely be zero in other
places.

Since commit 5f73e7d0386d ("kbuild: refactor cross-compiling
linux-headers package"), the linux-headers Debian package fails to
build when $(CC) cannot build userspace applications, for example,
when using toolchains installed by the 0day bot.
The host programs in the linux-headers package should be rebuilt using
the disto's cross-compiler, ${DEB_HOST_GNU_TYPE}-gcc instead of $(CC).
Hence, the variable 'CC' must be expanded in this shell script instead
of in the top-level Makefile.
Commit f354fc88a72a ("kbuild: install-extmod-build: add missing
quotation marks for CC variable") was not a correct fix because
CC="ccache gcc" should be unrelated when rebuilding userspace tools.

When CONFIG_OBJTOOL=y or CONFIG_DEBUG_INFO_BTF=y, parallel builds
show awkward "mkdir -p ..." logs.

Defining MAKEFLAGS=<value> on the command line wipes out command line
switches from the resultant MAKEFLAGS definition, even though the command
line switches are active. [1]
MAKEFLAGS puts all single-letter options into the first word, and that
word will be empty if no single-letter options were given. [2]
However, this breaks if MAKEFLAGS=<value> is given on the command line.
The tools/ and tools/% targets set MAKEFLAGS=<value> on the command
line, which breaks the following code in tools/scripts/Makefile.include:
short-opts := $(firstword -$(MAKEFLAGS))
If MAKEFLAGS really needs modification, it should be done through the
environment variable, as follows:
MAKEFLAGS=<value> $(MAKE) ...
That said, I question whether modifying MAKEFLAGS is necessary here.
The only flag we might want to exclude is --no-print-directory, as the
tools build system changes the working directory. However, people might
find the "Entering/Leaving directory" logs annoying.
I simply removed the offending MAKEFLAGS=<value>.

The current code tries to handle joiner vs. Y planes completely
independently. That does not really work since each pipe selects
its Y planes completely independently, and any plane pulled into
the state by one of the secondary pipes needs to have the plane
on the primary pipe also included in the state (for the uapi
state copy). The current code sometimes forgets to pull in planes
that we need, leading to weird things like the Y<->UV plane link
only getting torn down from one side but not the other.
Remedy the situation by pulling in the exact same set planes
on all the joined pipes. To calculate the set we simply
look through each joined crtc and any plane in the state gets
added to the set. However due to the way the Y plane selection
works we may not be able to determine the set in one go. One
plane on one pipe may pull in a Y plane, which may have to pull
in another plane because it's not acting in the same role on
another pipe, etc. The simple approach taken here is to keep
looping and adding planes to the set until it stops growing.
I suppose if we tracked more of this Y plane stuff in the
crtc state rather than the plane state we might be able to
do it in one go. But this works, and it's not going to loop
for long anyway since we only have so many pipes and Y planes
to consider.

Any active plane needs to have its crtc included in the atomic
state. For planes enabled via uapi that is all handler in the core.
But when we use a plane for joiner the uapi code things the plane
is disabled and therefore doesn't have a crtc. So we need to pull
those in by hand. We do it first thing in
intel_joiner_add_affected_crtcs() so that any newly added crtc will
subsequently pull in all of its joined crtcs as well.
The symptoms from failing to do this are:
- duct tape in the form of commit 1d5b09f8daf8 ("drm/i915: Fix NULL
ptr deref by checking new_crtc_state")
- the plane's hw state will get overwritten by the disabled
uapi state if it can't find the uapi counterpart plane in
the atomic state from where it should copy the correct state

syzkaller reported a use-after-free in geneve_find_dev() [0]
without repro.
geneve_configure() links struct geneve_dev.next to
net_generic(net, geneve_net_id)->geneve_list.
The net here could differ from dev_net(dev) if IFLA_NET_NS_PID,
IFLA_NET_NS_FD, or IFLA_TARGET_NETNSID is set.
When dev_net(dev) is dismantled, geneve_exit_batch_rtnl() finally
calls unregister_netdevice_queue() for each dev in the netns,
and later the dev is freed.
However, its geneve_dev.next is still linked to the backend UDP
socket netns.
Then, use-after-free will occur when another geneve dev is created
in the netns.
Let's call geneve_dellink() instead in geneve_destroy_tunnels().

When executing suspend to ram twice in a row,
the `rx_buf_nr` and `rx_buf_max_nr` increase to three times vq->num_free.
Then after virtqueue_get_buf and `rx_buf_nr` decreased
in function virtio_transport_rx_work,
the condition to fill rx buffer
(rx_buf_nr < rx_buf_max_nr / 2) will never be met.
It is because that `rx_buf_nr` and `rx_buf_max_nr`
are initialized only in virtio_vsock_probe(),
but they should be reset whenever virtqueues are recreated,
like after a suspend/resume.
Move the `rx_buf_nr` and `rx_buf_max_nr` initialization in
virtio_vsock_vqs_init(), so we are sure that they are properly
initialized, every time we initialize the virtqueues, either when we
load the driver or after a suspend/resume.
To prevent erroneous atomic load operations on the `queued_replies`
in the virtio_transport_send_pkt_work() function
which may disrupt the scheduling of vsock->rx_work
when transmitting reply-required socket packets,
this atomic variable must undergo synchronized initialization
alongside the preceding two variables after a suspend/resume.

Pull pci fixes from Bjorn Helgaas:
- Update a BUILD_BUG_ON() usage that works on current compilers, but
breaks compilation on gcc 5.3.1 (Alex Williamson)
- Avoid use of FLR for Mediatek MT7922 WiFi; the device previously
worked after a long timeout and fallback to SBR, but after a recent
RRS change it doesn't work at all after FLR (Bjorn Helgaas)
