James Bottomley 12e4d0cc2e plist: Add plist_last
plist is currently used by the scheduler, which only needs to know the
highest item in the list.  This adds plist_last which allows you to
find the lowest.  This is necessary for using plists to implement a
fast search of dynamic ranges in pm_qos which can have both highest
and lowest criteria.

Gregory Haskins 4075134e40 plist: fix PLIST_NODE_INIT to work with debug enabled
It seems that PLIST_NODE_INIT breaks if used and DEBUG_PI_LIST is defined.
Since there are no current users of PLIST_NODE_INIT, this has gone
undetected.  This patch fixes the build issue that enables the
DEBUG_PI_LIST later in the series when we use it in init_task.h

Remove '#' from beginning of kernel-doc comment macro names.
Remove extra (erroneous) blank lines in kernel-doc.

Thomas Gleixner b44597906e [PATCH] Fix plist include dependency
plist.h uses container_of, which is defined in kernel.h.
Include kernel.h in plist.h as the kernel.h include does not longer
happen automatically on all architectures.
