"Pre-multiplied" is the default pixel blend mode for KMS/DRM, as
documented in supported_modes of drm_plane_create_blend_mode_property():
https://cgit.freedesktop.org/drm/drm-misc/tree/drivers/gpu/drm/drm_blend.c
In this mode, both 'pixel alpha' and 'plane alpha' participate in the
calculation, as described by the pixel blend mode formula in KMS/DRM
documentation:
out.rgb = plane_alpha * fg.rgb +
(1 - (plane_alpha * fg.alpha)) * bg.rgb
Considering the blend config mechanisms we have in the driver so far,
the alpha mode that better fits this blend mode is the
_PER_PIXEL_ALPHA_COMBINED_GLOBAL_GAIN, where the value for global_gain
is the plane alpha (global_alpha).
With this change, alpha property stops to be ignored. It also addresses

perf_evsel::sample_id is an xyarray which can cause a segfault when
accessed beyond its size. e.g.
# perf record -e intel_pt// -C 1 sleep 1
Segmentation fault (core dumped)
#
That is happening because a dummy event is opened to capture text poke
events accross all CPUs, however the mmap logic is allocating according
to the number of user_requested_cpus.
In general, perf sometimes uses the evsel cpus to open events, and
sometimes the evlist user_requested_cpus. However, it is not necessary
to determine which case is which because the opened event file
descriptors are also in an xyarray, the size of whch can be used
to correctly allocate the size of the sample_id xyarray, because there
is one ID per file descriptor.
Note, in the affected code path, perf_evsel fd array is subsequently
used to get the file descriptor for the mmap, so it makes sense for the
xyarrays to be the same size there.

All of these properties are initialized by ARM Trusted Firmware, and
have been since the early days of this chip. It's redundant (and
possibly wrong) to do this here now. What's more, there seems to be some
confusion about the units and some of the definitions of this timing
struct: the DT docs say MHz for many of these, but downstream users were
in Hz (and therefore, the ATF interface was Hz). Also, the in-driver
usage for some of these (e.g., for comparing to target frequency) were
in Hz too. So doubly wrong.
We can avoid thinking about who got the right units by dropping the

The driver and all downstream device trees [1] are using Hz units, but

exceed 2^32-1 Hz, so the choice of unit doesn't really matter than much.
Rather than add unnecessary risk in getting the units wrong, let's just
go with the unofficial convention and make the docs match reality.
A sub-1MHz frequency is extremely unlikely, so include a minimum in the
schema, to help catch anybody who might have believed this was MHz.

* Renamed rockchip,dram_speed_bin to rockchip,ddr3_speed_bin. The
driver code and the example matched, but the description was
different. I went with the implementation. Note that this property is
also slated for deprecation/deletion in the subsequent patches.
* Drop upthreshold and downdifferential properties from the example.
These were undocumented (so, wouldn't pass validation), but were
representing software properties (governor tweaks). I drop them from
the driver in subsequent patches.
* Rename clock from pclk_ddr_mon to dmc_clk. The driver, DT example,
and all downstream users matched -- the binding definition was the
exception. Anyway, "dmc_clk" is a more appropriately generic name.
* Choose a better filename and location (this is a memory controller).

constraints that both arise from the block size of the AES cipher:
- The alignment required for the lengths of file contents blocks
- The minimum input/output length for the filenames encryption modes
Since there are way too many things called the "block size", and the
connection with the AES block size is not easily understood, split
FS_CRYPTO_BLOCK_SIZE into two constants FSCRYPT_CONTENTS_ALIGNMENT and
FSCRYPT_FNAME_MIN_MSG_LEN that more clearly describe what they are.

I messed up the delayed takover path in the locking conversion in
6e7da3af00 ("fbcon: Move console_lock for register/unlink/unregister").
If CONFIG_FRAMEBUFFER_CONSOLE_DEFERRED_TAKEOVER is enabled, fbcon take-over
doesn't take place when calling fbcon_fb_registered(). Instead, is deferred
using a workqueue and its fbcon_register_existing_fbs() function calls to
fbcon_fb_registered() again for each registered fbcon fb.
This leads to the console_lock tried to be held twice, causing a deadlock.
Fix it by re-extracting the lockless function and using it in the
delayed takeover path, where we need to hold the lock already to
iterate over the list of already registered fb. Well the current code
still is broken in there (since the list is protected by a
registration_lock, which we can't take here because it nests the other
way round with console_lock), but in the future this will be a list
protected by console_lock when this is all sorted out.
While reviewing the broken commit I realized that I've left some
outdated comments about the locking behind. Fix those too.

irq_poll_cpu_dead() pulls the blk_cpu_iopoll backlog from the dead CPU and
raises the POLL softirq with __raise_softirq_irqoff() on the CPU it is
running on. That just sets the bit in the pending softirq mask.
This means the handling of the softirq is delayed until the next interrupt
or a local_bh_disable/enable() pair. As a consequence the CPU on which this
code runs can reach idle with the POLL softirq pending, which triggers a
warning in the NOHZ idle code.
Add a local_bh_disable/enable() pair around the interrupts disabled section
in irq_poll_cpu_dead(). local_bh_enable will handle the pending softirq.

If kzalloc_node() in __smpboot_create_thread() fails then the rollback will
be done with st->cpu==0 causing CPU0 to be erroneously set to be dying,
causing the scheduler to get mightily confused and throw its toys out of

However the cpu number is actually available directly, so simply remove

ACPICA commit 2a0d1d475e7ea1c815bee1e0692d81db9a7c909c
Quick boottime is important, so warn about sleeps greater than 10 ms.
Distribution Linux kernels reach initrd in 350 ms, so excessive delays
should be called out. 10 ms is chosen randomly, but three of such delays
would already make up ten percent of the boottime.

ACPICA commit 05ba545ce7859392250b18c10081db25c90ed8d7
Values greater than 100 microseconds violate the ACPI specification, so
warn users about it.
From ACPI Specification version 6.2 Errata A, 19.6.128 *Stall (Stall for
a Short Time)*:
> The implementation of Stall is OS-specific, but must not relinquish
> control of the processor. Because of this, delays longer than 100
> microseconds must use Sleep instead of Stall.

ACPICA commit b69cbef7a83eadb102a1ff6c6f6fc5abce34805a
`how_long` refers to different units in both functions, so make it more
clear, what unit they expect. That also makes one comment superfluous.
