If r7 is zero at kernel boot, or does not point to a valid DTB, then
we fall back to a DTB (assumed to be) linked statically in the kernel, instead
of blindly copying bogus cruft into the kernel DTB memory region

Some 8168 are unable to WoL when receiving is not enabled (plain
old 8169 do not seem to care).
It is not exactly pretty to leave the receiver enabled but we
should now enable DMA late enough for it to be safe. Some late
stage boot failure due to pxe and friends may benefit from the
delayed enabling of bus-mastering as well.

Allocating new block group is easy when the disk has plenty of space.
But things get difficult as the disk fills up, especially if
the FS has been run through btrfs-vol -b. The balance operation
is likely to make the total bytes available on the device greater
than the largest extent we'll actually be able to allocate.
But the device extent allocation code incorrectly assumes that a device
with 5G free will be able to allocate a 5G extent. It isn't normally a
problem because device extents don't get freed unless btrfs-vol -b
is run.
This fixes the device extent allocator to remember the largest free
extent it can find, and then uses that value as a fallback.

Btrfs allocates individual extents from block groups, and each
block group has a specific type. It may hold metadata, data
mirrored or striped etc.
When we balance space (btrfs-vol -b) or remove a drive (btrfs-vol -r)
we free block groups. Once a block group is freed, the space it was
using on the device may be available for use by new block groups.
btrfs_remove_block_group was clearing the flag that said
'our devices are full, don't even try to allocate new block groups',
but it was only clearing that flag for a specific type of block group.
This commit clears the full flag for all of the types of block groups,
making it much more likely that we'll be able to balance space when
the drive is close to full.

The commit_transaction call to wait_ordered_extents when snap_pending
passes nocow_only=1 to process only NOCOW or PREALLOC extents. This isn't
correct for the 'flushoncommit' mode, as it skips extents we just started
IO on in start_delalloc_inodes.
So, in the flushoncommit case, wait on all ordered extents. Otherwise,
only pass the nocow_only flag to wait_ordered_extents if snap_pending.

Both tvaudio and the tuner share i2c address 0x42. The tvaudio module can
check whether it really is a tda9840, but the tuner can't. So the tvaudio
module must be loaded before the tuner module. This was also the case for
2.6.29, but the order was swapped in 2.6.30.

A recent patch didn't take into account that frontends can be compiled into
the kernel. Or that frontends compiled as modules can't be used by the
b2c2 driver if it is not a module itself.
Some frontends require multiple drivers, e.g. a demod driver and a tuner
driver. The code for the frontend support was getting added if the demod
driver was available. Change this to also require any needed tuner or SEC
drivers as well.

When the change was introduced in the zl10353 for the i2c gate behavior, this
broke the HVR-900 which was not behind a gate. Use a version of the zl10353
config profile that indicates the tuner is not behind such a gate.
Without this patch the first tune succeeds, but subsequent tuning attempts
will fail.
The change also renames the terratec zl10353 profile I wrote to be more
generic, since it is shared by the non-terratec device.

In cases where the device has a generic Empia USB ID, the call in the
precard setup phase did not set the tuner GPIO. As a result, the tuner may
not be taken out of reset before attempting initialization in the analog
driver.
This problem was not seen before with the EVGA inDtube, since that particular
board has the analog GPIO setup to include taking the tuner out of reset.
