Subject: linux-next: manual merge of the akpm-current tree with the tile
tree
Hi Andrew,
Today's linux-next merge of the akpm-current tree got a conflict in
Documentation/sysctl/kernel.txt between commit e164ade07b21 ("watchdog:
add watchdog_exclude sysctl to assist nohz") from the tile tree and
commit 25909f748a50 ("watchdog: update documentation for kernel params
and sysctl") from the akpm-current tree.
I fixed it up (see below) and can carry the fix as necessary (no action
is required).

+ watchdog:
+
+ This parameter can be used to disable or enable the soft lockup detector
+ _and_ the NMI watchdog (i.e. the hard lockup detector) at the same time.
+
+ 0 - disable both lockup detectors
+ 1 - enable both lockup detectors
+
+ The soft lockup detector and the NMI watchdog can also be disabled or
+ enabled individually, using the soft_watchdog and nmi_watchdog parameters.
+ If the watchdog parameter is read, for example by executing
+
+ cat /proc/sys/kernel/watchdog
+
+ the output of this command (0 or 1) shows the logical OR of soft_watchdog
+ and nmi_watchdog.
+
+ ==============================================================
+
+watchdog_exclude:
+
+This value can be used to control on which cpus the watchdog is
+prohibited from running. The default exclude mask is empty, but if
+NO_HZ_FULL is enabled in the kernel config, and cores are specified
+with the nohz_full= boot argument, those cores are excluded by default.
