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.

[CRYPTO] aes: Fixed array boundary violation
The AES setkey routine writes 64 bytes to the E_KEY area even though
there are only 60 bytes there. It is in fact safe since E_KEY is
immediately follwed by D_KEY which is initialised afterwards. However,
doing this may trigger undefined behaviour and makes Coverity unhappy.

altogether.

[CRYPTO] api: Align tfm context as wide as possible
Since tfm contexts can contain arbitrary types we should provide at least
natural alignment (__attribute__ ((__aligned__))) for them. In particular,
this is needed on the Xscale which is a 32-bit architecture with a u64 type
that requires 64-bit alignment. This problem was reported by Ronen Shitrit.
The crypto_tfm structure's size was 44 bytes on 32-bit architectures and
80 bytes on 64-bit architectures. So adding this requirement only means
that we have to add an extra 4 bytes on 32-bit architectures.
On i386 the natural alignment is 16 bytes which also benefits the VIA
Padlock as it no longer has to manually align its context structure to
128 bits.

other link local multicast addresses are ignored. This allows
for use of different multicast addresses to define separate STP
domains.
