-Subject: cls_matchall: avoid panic when receiving a packet before filter set
-
-From: Matteo Croce <mcroce@redhat.com>
-
-[ Upstream commit 25426043ec9e22b90c789407c28e40f32a9d1985 ]
-
-When a matchall classifier is added, there is a small time interval in
-which tp->root is NULL. If we receive a packet in this small time slice
-a NULL pointer dereference will happen, leading to a kernel panic:
-
- # tc qdisc replace dev eth0 ingress
- # tc filter add dev eth0 parent ffff: matchall action gact drop
- Unable to handle kernel NULL pointer dereference at virtual address 0000000000000034
- Mem abort info:

+Subject: drm: don't block fb changes for async plane updates
+
+From: Helen Koike <helen.koike@collabora.com>
+
+commit 89a4aac0ab0e6f5eea10d7bf4869dd15c3de2cd4 upstream.
+
+In the case of a normal sync update, the preparation of framebuffers (be
+it calling drm_atomic_helper_prepare_planes() or doing setups with
+drm_framebuffer_get()) are performed in the new_state and the respective
+cleanups are performed in the old_state.
+
+In the case of async updates, the preparation is also done in the
+new_state but the cleanups are done in the new_state (because updates
+are performed in place, i.e. in the current state).
+
+The current code blocks async udpates when the fb is changed, turning
+async updates into sync updates, slowing down cursor updates and
+introducing regressions in igt tests with errors of type:
+
+"CRITICAL: completed 97 cursor updated in a period of 30 flips, we
+expect to complete approximately 15360 updates, with the threshold set
+at 7680"
+
+Fb changes in async updates were prevented to avoid the following scenario:
+
+- Async update, oldfb = NULL, newfb = fb1, prepare fb1, cleanup fb1
+- Async update, oldfb = fb1, newfb = fb2, prepare fb2, cleanup fb2
+- Non-async commit, oldfb = fb2, newfb = fb1, prepare fb1, cleanup fb2 (wrong)
+Where we have a single call to prepare fb2 but double cleanup call to fb2.
+
+To solve the above problems, instead of blocking async fb changes, we
+place the old framebuffer in the new_state object, so when the code
+performs cleanups in the new_state it will cleanup the old_fb and we
+will have the following scenario instead:
+
+- Async update, oldfb = NULL, newfb = fb1, prepare fb1, no cleanup
+- Async update, oldfb = fb1, newfb = fb2, prepare fb2, cleanup fb1
+- Non-async commit, oldfb = fb2, newfb = fb1, prepare fb1, cleanup fb2
+
+Where calls to prepare/cleanup are balanced.

+commit 396dd8143bdd94bd1c358a228a631c8c895a1126 upstream.
+
+On many (all?) the Gemini Lake systems we work with, there is frequent
+momentary graphical corruption at the top of the screen, and it seems
+that disabling framebuffer compression can avoid this.
+
+The ticket was reported 6 months ago and has already affected a
+multitude of users, without any real progress being made. So, lets
+disable framebuffer compression on GeminiLake until a solution is found.

+
+From: Chris Wilson <chris@chris-wilson.co.uk>
+
+commit d90c06d57027203f73021bb7ddb30b800d65c636 upstream.
+
+This was supposed to be a mask of all known rings, but it is being used
+by execbuffer to filter out invalid rings, and so is instead mapping high
+unused values onto valid rings. Instead of a mask of all known rings,
+we need it to be the mask of all possible rings.

+Subject: drm/i915: Maintain consistent documentation subsection ordering
+
+From: Jonathan Corbet <corbet@lwn.net>
+
+commit 551bd3368a7b3cfef01edaade8970948d178d40a upstream.
+
+With Sphinx 2.0 (or prior versions with the deprecation warnings fixed) the
+docs build fails with:
+
+ Documentation/gpu/i915.rst:403: WARNING: Title level inconsistent:
+
+ Global GTT Fence Handling
+ ~~~~~~~~~~~~~~~~~~~~~~~~~
+
+ reST markup error:
+ Documentation/gpu/i915.rst:403: (SEVERE/4) Title level inconsistent:
+
+I "fixed" it by changing the subsections in i915.rst, but that didn't seem
+like the correct change. It turns out that a couple of i915 files create
+their own subsections in kerneldoc comments using apostrophes as the
+heading marker:
+
+ Layout
+ ''''''
+
+That breaks the normal subsection marker ordering, and newer Sphinx is
+rather more strict about enforcing that ordering. So fix the offending
+comments to make Sphinx happy.
+
+(This is unfortunate, in that kerneldoc comments shouldn't need to be aware
+of where they might be included in the heading hierarchy, but I don't see
+a better way around it).

+Subject: TTY: serial_core, add ->install
+
+From: Jiri Slaby <jslaby@suse.cz>
+
+commit 4cdd17ba1dff20ffc99fdbd2e6f0201fc7fe67df upstream.
+
+We need to compute the uart state only on the first open. This is
+usually what is done in the ->install hook. serial_core used to do this
+in ->open on every open. So move it to ->install.
+
+As a side effect, it ensures the state is set properly in the window
+after tty_init_dev is called, but before uart_open. This fixes a bunch
+of races between tty_open and flush_to_ldisc we were dealing with
+recently.
+
+One of such bugs was attempted to fix in commit fedb5760648a (serial:
+fix race between flush_to_ldisc and tty_open), but it only took care of
+a couple of functions (uart_start and uart_unthrottle). I was able to
+reproduce the crash on a SLE system, but in uart_write_room which is
+also called from flush_to_ldisc via process_echoes. I was *unable* to
+reproduce the bug locally. It is due to having this patch in my queue
+since 2012!
