Hi all,
Today's linux-next merge of the tip tree got a conflict in
Documentation/sysctl/kernel.txt between commit 7984754b99b6 ("kexec: add
sysctl to disable kexec_load") from Linus' tree and commit 270750dbc18a
("hung_task: Display every hung task warning") from the tip tree.
I fixed it up (see below) and can carry the fix as necessary (no action
is required).

==============================================================
+ hung_task_panic:
+
+ Controls the kernel's behavior when a hung task is detected.
+ This file shows up if CONFIG_DETECT_HUNG_TASK is enabled.
+
+ 0: continue operation. This is the default behavior.
+
+ 1: panic immediately.
+
+ ==============================================================
+
+ hung_task_check_count:
+
+ The upper bound on the number of tasks that are checked.
+ This file shows up if CONFIG_DETECT_HUNG_TASK is enabled.
+
+ ==============================================================
+
+ hung_task_timeout_secs:
+
+ Check interval. When a task in D state did not get scheduled
+ for more than this value report a warning.
+ This file shows up if CONFIG_DETECT_HUNG_TASK is enabled.
+
+ 0: means infinite timeout - no checking done.
+
+ ==============================================================
+
+ hung_task_warning:
+
+ The maximum number of warnings to report. During a check interval
+ When this value is reached, no more the warnings will be reported.
+ This file shows up if CONFIG_DETECT_HUNG_TASK is enabled.
+
+ -1: report an infinite number of warnings.

+ ==============================================================
+
+kexec_load_disabled:
+
+A toggle indicating if the kexec_load syscall has been disabled. This
+value defaults to 0 (false: kexec_load enabled), but can be set to 1
+(true: kexec_load disabled). Once true, kexec can no longer be used, and
+the toggle cannot be set back to false. This allows a kexec image to be
+loaded before disabling the syscall, allowing a system to set up (and
+later use) an image without it being altered. Generally used together
+with the "modules_disabled" sysctl.

kptr_restrict:
This toggle indicates whether restrictions are placed on
