This patch adds the ov511, quickcam_messenger, w9968cf, stv680 and ovcamchip
v4l1 drivers to the feature removal schedule as the devices they support
are now all also supported by v4l2 gspca sub drivers.
This patch also adds the v4l2 vc0301 driver for removal as it duplicates
functionality of the gspca_zc3xx driver, zc0301 only supports 2 USB-ID's
(because it only supports a limited set of sensors) wich are also
supported
by the gspca_zc3xx driver (which supports 53 USB-ID's in total).

Commit d899bf7b (procfs: provide stack information for threads) introduced
to show stack information in /proc/{pid}/status. But it cause large
performance regression. Unfortunately /proc/{pid}/status is used ps
command too and ps is one of most important component. Because both to
take mmap_sem and page table walk are heavily operation.
If many process run, the ps performance is,
[before d899bf7b]

Thus, this patch revert it. Fortunately /proc/{pid}/task/{tid}/smaps
provide almost same information. we can use it.
Commit d899bf7b introduced two features:
1) Add the annotattion of [thread stack: xxxx] mark to
/proc/{pid}/task/{tid}/maps.
2) Add StackUsage field to /proc/{pid}/status.
I only revert (2), because I haven't seen (1) cause regression.

The power management of some devices is handled through device types
and device classes rather than through bus types. Since these
devices may also benefit from using the run-time power management
core, extend it so that the device type and device class run-time PM
callbacks can be taken into consideration by it if the bus type
callback is not defined.
Update the run-time PM core documentation to reflect this change.
