The proposed patch is a helluva lot simpler than doing a 23 patch selective
backport.

* [igt-dev] [PATCH i-g-t v3 2/4] lib/igt_pm: Find HDA device when attempting to enable runtime PM
From: Tvrtko Ursulin @ 2018-07-23 15:31 UTC (permalink / raw)
To: igt-dev; +Cc: intel-gfx, Tvrtko Ursulin
In-Reply-To: <153235048851.26238.17694902495417158505@skylake-alporthouse-com>
From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>
HDA audio device can be present at various PCI paths on different systems
which the existing code did not account for.
Furthermore the failure to enable runtime PM was silent leaving callers
in the dark.
Improve it by auto-locating the PCI path and logging a warning when
something is not as expected.
v2:
* If there is no audio hw/driver there is no failure.
v3
* Comment.
* Skip non-symlinks.
* Free path on failure and restore.
* Simplify with asprintf. (Chris Wilson)

This debug data used to idenfiy the cause of the time out.

I believe that patch fixes a real issue, but it would
be nice if the code could be documented better so it
does not confuse people who look at the code later.

* [PATCH v3] mmc: sunxi: remove output of virtual base address

linux-arm-kernel-IAPFreCvJWM7uuMidbF8XUB+6BGkLq7r,
linux-sunxi-/JYPxA39Uh5TLH3MbocFFw
Recent Linux versions refuse to print actual virtual kernel addresses,
to not give a hint about the location of the kernel in a randomized virtual
address space. This affects the output of the sunxi MMC controller
driver, which now produces the rather uninformative line:
[ 1.482660] sunxi-mmc 1c0f000.mmc: base:0x(____ptrval____) irq:8
Since the virtual base address is not really interesting in the first
place, let's just drop this value. The same applies to Linux' notion of
the interrupt number, which is independent from the GIC SPI number.
We have the physical address as part of the DT node name, which is way
more useful for debugging purposes.
To keep a success message in the driver, we make this purpose explicit
with the word "initialized", plus print some information that is not too
obvious and that we learned while probing the device:
the maximum request size and whether it uses the new timing mode.
So the output turns into:
[ 1.750626] sunxi-mmc 1c0f000.mmc: initialized, max. request size: 16384 KB, uses new timings mode
[ 1.786699] sunxi-mmc 1c11000.mmc: initialized, max. request size: 2048 KB

Ok, thanks for the analysis, I had missed that and was about to
send a different patch to increase STRUCT_PAGE_MAX_SHIFT
in some configurations, which is not as good.

You could add further text here that I had just added to my
patch description (not sent):
Further experiments show that the build error already existed before,
but was only triggered with larger values of CONFIG_NR_CPU and/or
CONFIG_NODES_SHIFT that might be used in actual configurations but
not in randconfig builds.
With longer CPU and node masks, I could recreate the problem with
kernels as old as linux-4.7 when arm64 NUMA support got added.

* [Bug 107333] Display Not Detected If Powered Off When amdgpu.dc=1

--- Comment #2 from Benjamin Hodgetts <ben@xnode.org> ---
By "forced" I mean I specified amdgpu.dc=0 on the kernel command line to force
DC off (as it's on by default).
Yes to the second part of your question. Using dc=0 allows the display to be
properly detected, even if it's turned off.

I do not have the full context here but let me note that you should be
careful when doing top-down reservation because you can easily get into
hotplugable memory and break the hotremove usecase. We even warn when
this is done. See memblock_find_in_range_node

So...are you translating this into markdown format? Please don't do
that, we don't need another documentation format in the kernel. If you
want to convert this document to structured markup, the ideal approach
would be to convert the source document to RST first, then translate the
result.
Thanks,
jon
