rtc: rtc-hid-sensor-time: allow full years (16bit) in HID reports
The draft for HID-sensors (HUTRR39) currently doesn't define the range for
the attribute year. Asking one of the authors revealed that full years
(e.g. 2013 instead of just 13) were meant.
So we now allow both, 8 bit and 16 bit values for the attribute year and
assuming full years when the value is 16 bits wide.
We will still support 8 bit values until the specification gets final
(and maybe defines a way to set the time too).

autofs4: translate pids to the right namespace for the daemon
The PID and the TGID of the process triggering the mount are sent to the
daemon. Currently the global pid values are sent (ones valid in the
initial pid namespace) but this is wrong if the autofs daemon itself is
not running in the initial pid namespace.
So send the pid values that are valid in the namespace of the autofs daemon.
The namespace to use is taken from the oz_pgrp pid pointer, which was set
at mount time to the mounting process' pid namespace.
If the pid translation fails (the triggering process is in an unrelated
pid namespace) then the automount fails with ENOENT.

autofs4: allow autofs to work outside the initial PID namespace
Enable autofs4 to work in a "container". oz_pgrp is converted from pid_t
to struct pid and this is stored at mount time based on the "pgrp=" option
or if the option is missing then the current pgrp.
The "pgrp=" option is interpreted in the PID namespace of the current
process. This option is flawed in that it doesn't carry the namespace
information, so it should be deprecated. AFAICS the autofs daemon always
sends the current pgrp, which is the default anyway.
The oz_pgrp is also set from the AUTOFS_DEV_IOCTL_SETPIPEFD_CMD ioctl.
This ioctl sets oz_pgrp to the current pgrp. It is not allowed to change
the pid namespace.
oz_pgrp is used mainly to determine whether the process traversing the
autofs mount tree is the autofs daemon itself or not. This function now
compares the pid pointers instead of the pid_t values.
One other use of oz_pgrp is in autofs4_show_options. There is shows the
virtual pid number (i.e. the one that is valid inside the PID namespace
of the calling process)
For debugging printk convert oz_pgrp to the value in the initial pid
namespace.

checkpatch: create an EXPERIMENTAL --fix option to correct patches
Some patches have simple defects in whitespace and formatting that
checkpatch could correct automatically. Attempt to do so.
Add a --fix option to create a "<inputfile>.EXPERIMENTAL-checkpatch-fixes"
file that tries to use normal kernel style for some of these formatting
errors.
Add warnings against using this file without verifying the changes.
