Kirill Tkhai 1b2643f0d0 scripts/tags.sh: add ctags magic for declarations of popular kernel type
- Add magic for declarations of variables of popular kernel type like
  spinlock_t, list_head, wait_queue_head_t and other.

- Add a set of specially handled declaration extentions like
  __attribute, __aligned and other.

- Simplify pci_bus_* magic

Greg Kroah-Hartman af3b56289b time: don't inline EXPORT_SYMBOL functions
How is the compiler even handling exported functions that are marked
inline? Anyway, these shouldn't be inline because of that, so remove
that marking.

Based on a larger patch by Mark Charlebois to get LLVM to build the
kernel.

Jingoo Han d3ed97035b video: exynos_dp: add missing of_node_put()
of_find_node_by_name() returns a node pointer with refcount incremented,
use of_node_put() on it when done.

of_find_node_by_name() will call of_node_put() against the node pass to
from parameter, thus we also need to call of_node_get(from) before calling
of_find_node_by_name().

Commit 16559ae48c ("kgdb: remove #include <linux/serial_8250.h> from

implicitly include linux/platform_device.h.  The mmp framebuffer driver
is new, so Greg did not have a chance to fix it up when introducing his
change.

Zhou Zhu 59393bb94c video: mmp display subsystem
Add mmp display subsystem to support Marvell MMP display controllers.

This subsystem contains 4 parts:
--fb folder
--core.c
--hw folder
--panel folder

1. fb folder contains implementation of fb.  fb get path and overlay
   from common interface and operates on these structures.

2. core.c provides common interface for a hardware abstraction.  Major
   parts of this interface are:

   a) Path: path is a output device connected to a panel or HDMI TV.  Main
      operations of the path is set/get timing/output color.  fb operates
      output device through path structure.

   b) Ovly: Ovly is a buffer shown on the path.

      Ovly describes frame buffer and its source/destination size, offset,
      input color, buffer address, z-order, and so on.  Each fb device maps
      to one overlay.

3. hw folder contains implementation of hardware operations defined by
   core.c.  It registers paths for fb use.

4. panel folder contains implementation of panels.  It's connected to
   path.  Panel drivers would also regiester panels and linked to path
   when probe.

Arve Hjønnevåg c289ba2d26 goldfish: framebuffer driver
Framebuffer support for the Goldfish emulator.  This takes the Google
emulator and applies the x86 cleanups as well as moving the blank
methods to the usual Linux place and dropping the Android early suspend
logic (for now at least, that can be looked at as Android and upstream
converge).  Dropped various oddities like setting MTRRs on a virtual
frame buffer emulation...

With the drivers so far you can now boot a Linux initrd and have fun.

[sheng@linux.intel.com: cleaned up to handle x86]
[thomas.keel@intel.com: ported to 3.4]
[alan@linux.intel.com: cleaned up for style and 3.7, moved blank methods]
