Remove cachep->spinlock. Locking has moved to the kmem_list3 and most of

[PATCH] hugepage allocator cleanup
Insert "fresh" huge pages into the hugepage allocator by the same means as
they are freed back into it. This reduces code size and allows
enqueue_huge_page to be inlined into the hugepage free fastpath.
Eliminate occurances of hugepages on the free list with non-zero refcount.
This can allow stricter refcount checks in future. Also required for
lockless pagecache.

[PATCH] mm: simplify vmscan vs release refcounting
The VM has an interesting race where a page refcount can drop to zero, but it
is still on the LRU lists for a short time. This was solved by testing a 0->1
refcount transition when picking up pages from the LRU, and dropping the
refcount in that case.
Instead, use atomic_add_unless to ensure we never pick up a 0 refcount page
from the LRU, thus a 0 refcount page will never have its refcount elevated
until it is allocated again.

V4L/DVB (3545): Fixed no_overlay option and quirks on saa7134 driver
Some chipsets have several problems when pci to pci transfers are activated
on overlay mode. the option no_overlay allows disabling such feature of
the driver, in favor of keeping the system stable.
The default is to use pcipci_fail flag defined on drivers/pci/quirks.c.
It also allows the user to override it by forcing disable overlay or forcing
enable. Forcing enable may generate PCI transfer corruption, including disk
mass corruption, so should be used with care.
Added a text description to this option and make messages looks the same at
both bttv and saa7134 drivers.
Add wss_cfg_4_3 and wss_cfg_16_9 configuration options.
Firmware 2623 or later required.
Both parameters are bit masks:
- bit 15: disable WSS
- bit 14: send short WSS burst, then turn off WSS
- bit 13..0: WSS bits as specified by the standard
These parameters are useful if you own a broken tv set which
does not handle wss correctly.
Default settings:
- wss_cfg_4_3: 0x4008
- wss_cfg_16_9: 0x0007
These should work with most devices.

The msp3400 driver is currently only being built if

msp3400 in the Makefile is no longer appropriate.

V4L/DVB (3504): Medion 7134: Autodetect second bridge chip
The device, Medion 7134, has two saa7134 chips on it, but only one of them
is functional in the current saa7134 driver.
This patch adds autodetection for the second, unsupported saa7134 chip,
as SAA7134_BOARD_MD7134_BRIDGE_2, and displays a message to the user
(in dmesg) indicating that the second chip isn't yet functional.
This is useful for users, since two instances of the saa7134 driver
will spawn. This patch will prevent confusion by warning the user that
only one of the chips on the board are functional.
There are other versions of the SAA7134_BOARD_MD7134 with only a single
saa7134 bridge/decoder -- those devices will not be affected by this patch.
Only devices containing the second chip will display the warning.

V4L/DVB (3502): Saa7134: make unsupported secondary decoder message generic
There are already some supported devices that contain two
saa713x chips on-board, where only one of these chips is
currently functional in the driver.
We are already printing a warning message for the second
saa7134 decoder in SAA7134_BOARD_AVERMEDIA_A169_B. This
patch alters that case to make it generic, so that other
cards in the same situation can use it.

V4L/DVB (3500): Ringbuffer: don't reset pointers to zero
Oliver Endriss spotted, that resetting read and write pointers on
flush() requires additional locking and breaks the av7110 driver.
Therefore this patch partially reverts the previous patch titled "make
dvb_ringbuffer compatible to dmxdev_buffer".
