[GIT PULL] watchdog updates for Linux 4.4

[Guenter Roeck <linux@roeck-us.net>]

Hi Wim,

This is my watchdog pull request for 4.4. The branch is currently based
on v4.3-rc7. It includes a merge with the immutable branch published by Lee
Jones.

Please consider pulling watchdog updates for Linux 4.4 from signed tag:

    git://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging.git watchdog-for-wim-4.4

The tag has been applied on top of the watchdog-next branch. The branch includes
a number of patches I collected over the last few months. It does not include
all submitted patches; only the ones I reviewed and felt comfortable with are
included. Some may already be in your -next branch.

I reviewed all patches and ran build tests as well as source verification tests
with both smatch and spatch. The branch has been on my Linux repository for a
while, so presumably Fenguang's robot will have built the code as well. The most
recent build results are available at http://server.roeck-us.net:8010/builders,
in the watchdog-next column.

If you don't want to apply the entire series, please consider applying whatever
subset you might feel comfortable with.

Thanks,
Guenter
