When swapping in, or under memory pressure ttm_tt_populate() may sleep
for a substantiable amount of time. Allow interrupts during the sleep.
This will also allow us to inject -EINTR errors during swapin in upcoming
patches.
Also avoid returning VM_FAULT_OOM, since that will confuse the core
mm, making it print out a confused message and retrying the fault.
Return VM_FAULT_SIGBUS also under OOM conditions.

When swapping out, we will split multi-order pages both in order to
move them to the swap-cache and to be able to return memory to the
swap cache as soon as possible on a page-by-page basis.
Reduce the page max order to the system PMD size, as we can then be nicer
to the system and avoid splitting gigantic pages.
Looking forward to when we might be able to swap out PMD size folios
without splitting, this will also be a benefit.
v2:
- Include all orders up to the PMD size (Christian König)
v3:
- Avoid compilation errors for architectures with special PFN_SHIFTs

When hitting an error, the error path forgot to unmap dma mappings and
could call set_pages_wb() on already uncached pages.
Fix this by introducing a common ttm_pool_free_range() function that
does the right thing.

- Simplify that common function (Christian König)
v3:
- Rename that common function to ttm_pool_free_range() (Christian König)

If the crtc is being switched on or off then the semantics of
computing the timestampe of the next vblank is somewhat ill-defined.
And indeed, the code splats with a warning in the timestamp
computation code. Specifically it hits the check to make sure that
atomic drivers have full set up the timing constants in the drm_vblank
structure, and that's just not the case before the crtc is actually
on.
For robustness it seems best to just not set deadlines for modesets.
v2: Also skip on inactive crtc (Ville)

MAX_ORDER currently defined as number of orders page allocator supports:
user can ask buddy allocator for page order between 0 and MAX_ORDER-1.
This definition is counter-intuitive and lead to number of bugs all over
the kernel.
Change the definition of MAX_ORDER to be inclusive: the range of orders
user can ask from buddy allocator is 0..MAX_ORDER now.

Apparently drivers need to check all this stuff themselves, which for
most things makes sense I guess. And for everything else we luck out,
because modern distros stopped supporting any other fbdev drivers than
drm ones and I really don't want to argue anymore about who needs to
check stuff. Therefore fixing all this just for drm fbdev emulation is
good enough.
Note that var->active is not set or validated. This is just control

This helper does not produce a real modalias, but tries to get the
"product" compatible part of the "vendor,product" compatibles only. It
is far from creating a purely useful modalias string and does not seem
to be used like that directly anyway, so let's try to give this helper a
more meaningful name before moving there a real modalias helper (already
existing under of/device.c).
Also update the various documentations to refer to the strings as
"aliases" rather than "modaliases" which has a real meaning in the Linux
kernel.
There is no functional change.

MESA driver is creating protected context on every driver handle
creation to query caps bits for app. So when running CI tests,
they are observing hundreds of drm_errors when enabling PXP
in .config but using SOC fusing or BIOS configuration that cannot
support PXP sessions.
The fixes tag referenced below was to resolve a related issue
where we wanted to silence error messages, but that case was due
to outdated IFWI (firmware) that definitely needed an upgrade and
was, at that point, considered a one-off case as opposed to today's
realization that default CI was enabling PXP in kernel config for
all testing.
So with this patch, let's strike a balance between issues that is
critical but are root-caused from HW/platform gaps (louder drm-warn
but just ONCE) vs other cases where it could also come from session
state machine (which cannot be a WARN_ONCE since it can be triggered
due to runtime operation events).
Let's use helpers for these so as more functions are added in future
features / HW (or as FW designers continue to bless upstreaming of
the error codes and meanings), we only need to update the helpers.
NOTE: Don't completely remove FW errors (via drm_debug) or else cusomer
apps that really needs to know that content protection failed won't
be aware of it.
v2: - Add fixes tag (Trvtko)
v3: - Break multi-line drm_dbg strings into separate drm_dbg (Daniele)
- Fix couple of typecasting nits (Daniele)
v4: - Unsuccessful PXP FW cmd due to platform configuration shouldn't
use drm_WARN_once (Tvrtko), Switched to use drm_info_once.
v5: - Added "reported-and-tested" by Eero.

Enabling kernel-doc warnings in commit aaee4bbe8a1a ("drm/i915: enable

we need something more to check for kernel-doc issues in headers. Add it
as part of the existing HDRTEST.
We have tons of issues, and this unleashes warnings galore on
CONFIG_DRM_I915_WERROR=y. It doesn't fail the build because (at least
for now) we don't pass -Werror to kernel-doc.

The LDB driver currently checks whether dual mode is used, otherwise it
assumes only channel 0 is in use. Add support for using only channel 1. In
device tree terms, this means linking port 2 only.
Doing this cleanly requires changing the logic of the probe functions from
this:
1. use of_graph_get_remote_node() on port 1 to find the panel
2. use drm_of_lvds_get_dual_link_pixel_order() to detect dual mode
to this:
1. use of_graph_get_remote_node() twice to find remote ports
2. reuse the result of the above to know whether each channel is enabled
and to find the panel
3. if (both channels as enabled)
use drm_of_lvds_get_dual_link_pixel_order() to detect dual mode
Also add a dev_dbg() to log the detected mode and log an error in case no
panel was found (no channel enabled).

In cases where the DSI module is left on by the bootloader
some panels may fail to initialize if the enable register is not cleared
before the panel's initialization sequence is sent, so clear it if that
is the case.

Return dev_err_probe() directly, because the return value of
dev_err_probe() is the appropriate error code, and it can
reduce code size, simplify the code.

When possible use dev_err_probe help to properly deal with the
PROBE_DEFER error, the benefit is that DEFER issue will be logged
in the devices_deferred debugfs file.
And using dev_err_probe() can reduce code size, the error value
gets printed.

A call to platform_get_irq() already prints an error on failure within
its own implementation. So printing another error based on its return
value in the caller is redundant and should be removed. The clean up
also makes if condition block braces unnecessary. Remove that as well.
Issue identified using platform_get_irq.cocci coccicheck script.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.
