Correct firmware type to MTS
Correct audio routing for composite/s-video
Add DVB-T detection.
This patch uses the eeprom hash method for detection as the vendor/product
ids are also used for the DIGIVOX_AD. This may be a clone of the same
product. Explanatory text has been added prior to the hask look-up in
anticipation that it may help others.
The following has been tested to work:
Analogue TV (PAL-I)
Composite In
DVB-T (UK Crystal Palace)
USB AUDIO
The following has not been tested but probably works:

Basic vfs-level fiemap infrastructure, which sets up a new ->fiemap
inode operation.
Userspace can get extent information on a file via fiemap ioctl. As input,
the fiemap ioctl takes a struct fiemap which includes an array of struct
fiemap_extent (fm_extents). Size of the extent array is passed as
fm_extent_count and number of extents returned will be written into
fm_mapped_extents. Offset and length fields on the fiemap structure
(fm_start, fm_length) describe a logical range which will be searched for
extents. All extents returned will at least partially contain this range.
The actual extent offsets and ranges returned will be unmodified from their
offset and range on-disk.
The fiemap ioctl returns '0' on success. On error, -1 is returned and errno
is set. If errno is equal to EBADR, then fm_flags will contain those flags
which were passed in which the kernel did not understand. On all other
errors, the contents of fm_extents is undefined.
As fiemap evolved, there have been many authors of the vfs patch. As far as
I can tell, the list includes:

With modern hard drives, reading 64k takes roughly the same time as
reading a 4k block. So request readahead for adjacent inode table
blocks to reduce the time it takes when iterating over directories
(especially when doing this in htree sort order) in a cold cache case.
With this patch, the time it takes to run "git status" on a kernel
tree after flushing the caches via "echo 3 > /proc/sys/vm/drop_caches"
is reduced by 21%.

There's already a fc_vport_termintate() call exported by
the transport. This patch adds a symmetric call to the API to allow
an NPIV-capable LLD to instantiate vports sans user intervention.
Additional comments/updates:
Re: scsi_fc_transport.txt
Add a function prototype for fc_vport_terminate similar to what's
done for fc_vport_create
Re: fc_vport_create
I recommend we pass the channel number in fc_vport_create rather
than fixing it at zero.
Also, ids->vport_type should be set to FC_PORTTYPE_NPIV prior to
calling fc_vport_create. The comment is also meaningless.

This patch against tip/x86/iommu virtually reverts
2842e5bf3115193f05dc9dac20f940e7abf44c1a. But just reverting the
commit breaks AMD IOMMU so this patch also includes some fixes.
The above commit adds new two options to x86 IOMMU generic kernel boot
options, fullflush and nofullflush. But such change that affects all
the IOMMUs needs more discussion (all IOMMU parties need the chance to
discuss it):
