drm/atomic: Use new iterator macros in drm_atomic_helper_wait_for_flip_done, again.
for_each_obj_in_state is about to be removed, so use the correct new
iterator macro.
I renamed the variable to 'unused', but forgot to convert
drm_atomic_helper_wait_for_flip_done to the new iterator macro,
so make it work this time.

dma-buf/sw_sync: clean up list before signaling the fence
If userspace already dropped its own reference by closing the sw_sync
fence fd we might end up in a deadlock where
dma_fence_is_signaled_locked() will trigger the release of the fence and
thus try to hold the lock to remove the fence from the list.
dma_fence_is_signaled_locked() tries to release/free the fence and hold
the lock in the process.
We fix that by changing the order operation and clean up the list and
rb-tree first.

dma-buf/sync_file: Allow multiple sync_files to wrap a single dma-fence
Up until recently sync_file were create to export a single dma-fence to
userspace, and so we could canabalise a bit insie dma-fence to mark
whether or not we had enable polling for the sync_file itself. However,
with the advent of syncobj, we do allow userspace to create multiple

validation framework also started returning multiple sync-files wrapping
a single dma-fence for a syncpt also triggering the problem.)

single bit in the shared dma-fence and restores the sync_file->flags for

drm/vc4: Add an ioctl for labeling GEM BOs for summary stats
This has proven immensely useful for debugging memory leaks and
overallocation (which is a rather serious concern on the platform,
given that we typically run at about 256MB of CMA out of up to 1GB
total memory, with framebuffers that are about 8MB ecah).
The state of the art without this is to dump debug logs from every GL
application, guess as to kernel allocations based on bo_stats, and try
to merge that all together into a global picture of memory allocation
state. With this, you can add a couple of calls to the debug build of
the 3D driver and get a pretty detailed view of GPU memory usage from
/debug/dri/0/bo_stats (or when we debug print to dmesg on allocation
failure).
The Mesa side currently labels at the gallium resource level (so you
see that a 1920x20 pixmap has been created, presumably for the window
system panel), but we could extend that to be even more useful with
glObjectLabel() names being sent all the way down to the kernel.
(partial) example of sorted debugfs output with Mesa labeling all
resources:
kernel BO cache: 16392kb BOs (3)
tiling shadow 1920x1080: 8160kb BOs (1)
resource 1920x1080@32/0: 8160kb BOs (1)
scanout resource 1920x1080@32/0: 8100kb BOs (1)
kernel: 8100kb BOs (1)
v2: Use strndup_user(), use lockdep assertion instead of just a
comment, fix an array[-1] reference, extend comment about name
freeing.

Daniel Vetter [Thu, 6 Jul 2017 13:00:21 +0000 (15:00 +0200)]
drm/fb-helper: Support deferred setup
FB helper code falls back to a 1024x768 mode if no outputs are connected
or don't report back any modes upon initialization. This can be annoying
because outputs that are added to FB helper later on can't be used with
FB helper if they don't support a matching mode.
The fallback is in place because VGA connectors can happen to report an
unknown connection status even when they are in fact connected.
Some drivers have custom solutions in place to defer FB helper setup
until at least one output is connected. But the logic behind these
solutions is always the same and there is nothing driver-specific about
it, so a better alterative is to fix the FB helper core and add support
for all drivers automatically.
This patch adds support for deferred FB helper setup. It checks all the
connectors for their connection status, and if all of them report to be
disconnected marks the FB helper as needing deferred setup. Whet setup
is deferred, the FB helper core will automatically retry setup after a
hotplug event, and it will keep trying until it succeeds.
v2: Rebase onto my entirely reworked fbdev helper locking. One big
difference is that this version again drops&reacquires the fbdev lock
(which is now fb_helper->lock, but before this patch series it was
mode_config->mutex), because register_framebuffer must be able to
recurse back into fbdev helper code for the initial screen setup.
v3: __drm_fb_helper_initial_config must hold fb_helper->lock upon
return, I've fumbled that in the deferred setup case (Liviu).
v4: I was blind, redo this all. __drm_fb_helper_initial_config
shouldn't need to reacquire fb_helper->lock, that just confuses
callers. I myself got confused by kernel_fb_helper_lock and somehow
thought it's the same as fb_helper->lock. Tsk.
Also simplify the logic a bit (we don't need two functions to probe
connectors), we can stick much closer to the existing code. And update
some comments I've spotted that are outdated.
v5: Don't pass -EAGAIN to drivers, it's just an internal error code
(Liviu).
v6: Add _and_unlock suffix to clarify locking (Maarten)

Properly alphabetize MAINTAINERS file
This adds a perl script to actually parse the MAINTAINERS file, clean up
some whitespace in it, warn about errors in it, and then properly sort
the end result.
My perl-fu is atrocious, so the script has basically been created by
randomly putting various characters in a pile, mixing them around, and
then looking it the end result does anything interesting when used as a
perl script.

Fix up MAINTAINERS file problems
Prepping for scripting the MAINTAINERS file cleanup (and possible split)
showed a couple of cases where the headers for a couple of entries were
bogus.
There's a few different kinds of bogosities:
- the X-GENE SOC EDAC case was confused and split over two lines
- there were four entries for "GREYBUS PROTOCOLS DRIVERS" that were all
different things.
- the NOKIA N900 CAMERA SUPPORT" was duplicated
all of which were more obvious when you started doing associative arrays
in perl to track these things by the header (so that we can alphabetize
this thing properly, and so that we might split it up by the data too).

xen/balloon: don't online new memory initially
When setting up the Xenstore watch for the memory target size the new
watch will fire at once. Don't try to reach the configured target size
by onlining new memory in this case, as the current memory size will
be smaller in almost all cases due to e.g. BIOS reserved pages.
Onlining new memory will lead to more problems e.g. undesired conflicts
with NVMe devices meant to be operated as block devices.
Instead remember the difference between target size and current size
when the watch fires for the first time and apply it to any further
size changes, too.
In order to avoid races between balloon.c and xen-balloon.c init calls
do the xen-balloon.c initialization from balloon.c.

xen/x86: fix cpu hotplug

cpu_startup_entry(CPUHP_AP_ONLINE_IDLE) from xen_play_dead()")
introduced an error leading to a stack overflow of the idle task when
a cpu was brought offline/online many times: by calling
cpu_startup_entry() instead of returning at the end of xen_play_dead()
do_idle() would be entered again and again.
Don't use cpu_startup_entry(), but cpuhp_online_idle() instead allowing
to return from xen_play_dead().

xen/grant-table: log the lack of grants
log a message when we enter this situation:
1) we already allocated the max number of available grants from hypervisor
and
2) we still need more (but the request fails because of 1)).
Sometimes the lack of grants causes IO hangs in xen_blkfront devices.
Adding this log would help debuging.

CONFIG_BOOTPARAM_HOTPLUG_CPU0 allows to offline CPU0 but Xen HVM guests
BUG() in xen_teardown_timer(). Remove the BUG_ON(), this is probably a
