-Subject: [PATCH 2/7] e1000e: Fix e1000_check_for_copper_link_ich8lan return
- value.
-
-e1000e_check_for_copper_link() and e1000_check_for_copper_link_ich8lan()
-are the two functions that may be assigned to mac.ops.check_for_link when
-phy.media_type == e1000_media_type_copper. Commit 19110cfbb34d ("e1000e:
-Separate signaling for link check/link up") changed the meaning of the
-return value of check_for_link for copper media but only adjusted the first
-function. This patch adjusts the second function likewise.

+ lookup.
+
+When we do tunnel or beet mode, we pass saddr and daddr from the
+template to xfrm_state_find(), this is ok. On transport mode,
+we pass the addresses from the flowi, assuming that the IP
+addresses (and address family) don't change during transformation.
+This assumption is wrong in the IPv4 mapped IPv6 case, packet
+is IPv4 and template is IPv6.
+
+Fix this by catching address family missmatches of the policy
+and the flow already before we do the lookup.

+ asked for
+
+In commit dc911f5bd8aa ("drm/i915/edp: Allow alternate fixed mode for
+eDP if available."), the patch allows for the use of an alternate fixed
+mode if it is available, but the patch was not ensuring that the only
+time the alternate mode is used is when it is specifically requested.
+This patch adds an additional comparison to intel_edp_compare_alt_mode
+to ensure that we only use the alternate mode if it is directly
+requested.
+
+Fixes: dc911f5bd8aac ("Allow alternate fixed mode for eDP if available.")

-Subject: [PATCH 6/7] cgroup: fix css_task_iter crash on CSS_TASK_ITER_PROC
-
-While teaching css_task_iter to handle skipping over tasks which
-aren't group leaders, bc2fb7ed089f ("cgroup: add @flags to
-css_task_iter_start() and implement CSS_TASK_ITER_PROCS") introduced a
-silly bug.
-
-CSS_TASK_ITER_PROCS is implemented by repeating
-css_task_iter_advance() while the advanced cursor is pointing to a
-non-leader thread.  However, the cursor variable, @l, wasn't updated
-when the iteration has to advance to the next css_set and the
-following repetition would operate on the terminal @l from the
-previous iteration which isn't pointing to a valid task leading to
-oopses like the following or infinite looping.

-Fix it by moving the initialization of the cursor below the repeat
-label.  While at it, rename it to @next for readability.
