Have you measured that? I do not think it would be super hard to
measure. I would be quite surprised if this added much if anything at
all as the whole struct page should be in the cache line already. We do
set reference count and other struct members. Almost nobody should be

OSS drivers are left as badly unmaintained, and now we're facing a
problem to clean up the hackish set_fs() usage in their codes. Since
most of drivers have been covered by ALSA, and the others are dead old
and inactive, let's leave them RIP.
This patch is the first step: disable the build of OSS

I'm not ingo, but I don't like that patch. It's in the wrong place -
that system call return code is too timing-critical to add address

Use time_after kernel macro for time comparison
that has safety check.

The timings are those that the firmware defines as the baseline, which
will be modified by the bridge/host as necessary to get the clocking
to work.

This driver communicates with the Atmel microcontroller for sequencing
the poweron of the TC358762 DSI-DPI bridge and controlling the

The Raspberry Pi 7" Touchscreen is a DPI touchscreen panel with
DSI->DPI bridge and touchscreen controller integrated, that connects

BCM2835's PLLD_DSI1 divider doesn't give us many choices for our pixel
clocks, so to support panels on the Raspberry Pi we need to set a
higher pixel clock rate than requested and adjust the mode we program
to extend out the HFP so that the refresh rate matches.

Here's the rewrite of the Raspberry Pi display support to split out a
bridge driver representing the toshiba+atmel pair. It depends on the
panel-bridge layer I've submitted.
The RPi DSI stack isn't completely working yet -- I've got some
flickery pixels on the display where it seems some color va

Sometimes we have to dereference next field of llist node before entering
loop becasue the node might be deleted or the next field might be
modified within the loop. So this adds the safe version of llist_for_each,
that is, llist_for_each_safe.

pick_next_pushable_dl_task(rq) has BUG_ON(rq->cpu != task_cpu(task))
when it returns a task other than NULL, which means that task_cpu(task)
must be rq->cpu. So if task == next_task, then task_cpu(next_task) must
be rq->cpu as well. Remove the redundant condition and make code simpler.
