[media] videobuf2: Do not unconditionally map S/G buffers into kernel space
The one in-tree videobuf2-dma-sg driver (mmp-camera) has no need for a
kernel-space mapping of the buffers; one suspects that most other drivers
would not either. The videobuf2-dma-sg module does the right thing if
buf->vaddr == NULL - it maps the buffer on demand if somebody needs it. So
let's not map the buffer at allocation time; that will save a little CPU
time and a lot of address space in the vmalloc range.

[media] mceusb: issue device resume cmd when needed
According to MS docs, the device firmware may halt after receiving an
unknown instruction, but that it should be possible to tell the firmware
to continue running by simply sending a device resume command. So lets
do that.

[media] Fix wrong register mask in gspca/sonixj.c
Hello,
When migrating from Slackware 13.1 to 13.37 (kernel 2.6.33.x to
2.6.37.6), there was some sort of regression with the external webcam
installed at the notebook (0x45:6128, SN9C325+OM6802).
In the version 2.6.37.6, the images got *very* dark, making the webcam
almost unusable, unless if used with direct sunlight.
Tracing back what happened, I concluded that changeset
0e4d413af
caused some sort of odd effects - including this - to this specific model.

eCryptfs: Unlock keys needed by ecryptfsd
Fixes a regression caused by
b5695d04634fa4ccca7dcbc05bb4a66522f02e0b
Kernel keyring keys containing eCryptfs authentication tokens should not
be write locked when calling out to ecryptfsd to wrap and unwrap file
encryption keys. The eCryptfs kernel code can not hold the key's write
lock because ecryptfsd needs to request the key after receiving such a
request from the kernel.
Without this fix, all file opens and creates will timeout and fail when
using the eCryptfs PKI infrastructure. This is not an issue when using
passphrase-based mount keys, which is the most widely deployed eCryptfs
configuration.

[media] em28xx: Fix DVB-C maxsize for em2884
The logic at em28xx_isoc_dvb_max_packetsize() sucks, at least for newer
the needed packet size. Yet, it is better than nothing.
Rewrite the code in order to change the default to 752 for em2884 and
newer chips and provide a better way to handle per-chipset specifics.
For em2874, the current default should be enough, as the only em2874
board is currently a 1-seg ISDB-T board, so, it needs only a limited
amount of bandwidth.

[media] tda18271c2dd: Fix saw filter configuration for DVB-C @6MHz
Currently, the driver assumes that all QAM carriers are spaced with
8MHz. This is wrong, and may decrease QoS on Countries like Brazil,
that have DVB-C carriers with 6MHz-spaced.
Fortunately, both ITU-T J-83 and EN 300 429 specifies a way to
associate the symbol rate with the bandwidth needed for it.
For ITU-T J-83 2007 annex A, the maximum symbol rate for 6 MHz is:
6 MHz / 1.15 =
5217391 Bauds
For ITU-T J-83 2007 annex C, the maximum symbol rate for 6 MHz is:
6 MHz / 1.13 =
5309735 Bauds.
As this tuner is currently used only for DRX-K, and it is currently
hard-coded to annex A, I've opted to use the roll-off factor of 0.15,
instead of 0.13.
If we ever support annex C, the better would be to add a DVB S2API
call to allow changing between Annex A and C, and add the 0.13 roll-off
factor to it.
This code is currently being used on other frontends, so I think we
should later add a core function with this code, to warrant that
it will be properly implemented everywhere.

at91: use structure to store the current soc
instead of reading the registers everytime
the current implementation respect the following constrain:
- allow 1 to n soc to be enabled
- allow to have a virtual cpu type and subtype
- always detect the cpu type and subtype and report it
- detect if the soc support is enabled
- prepare for sysfs export support
- drop soc specific code via compiler when the soc not enabled
(via cpu_is_xxx)
Today if we read the exid we will have the same value for 9g35 and 9m11
and we will need to check the cidr too
with the new implementation we just need to check the soc subtype
this will also allow to have specific virtual subtype for rm9200 which the
board will have to specify via at91rm9200_set_type(int) as we have no way to
detect it.
this implementation is inspired by the SH cpu detection support
