ext4: Fix fallocate to update the file size in each transaction
ext4_fallocate needs to update file size in each transaction. Otherwise

retry allocation due to ENOSPC, make sure we reset the variable ret so
that we actually do a retry.
Fail migrate if we allocated new blocks via mmap write.
If we write to holes in the file via mmap, we end up allocating
new blocks. This block allocation happens without taking inode->i_mutex.
Since migrate is protected by i_mutex and migrate expects that no
new blocks get allocated during migrate, fail migrate if new blocks
get allocated.
We can't take inode->i_mutex in the mmap write path because that
would result in a locking order violation between i_mutex and mmap_sem.
Also adding a separate rw_sempahore for protection is really high overhead
for a rare operation such as migrate.

ext4: ENOSPC error handling for writing to an uninitialized extent
This patch handles possible ENOSPC errors when writing to an

A write to a prealloc area causes the split of an unititalized extent
into initialized and uninitialized extents. If we don't have
space to add new extent information, instead of returning error,
convert the existing uninitialized extent to initialized one. We
need to zero out the blocks corresponding to the entire extent to
prevent uninitialized data reaching userspace.

ext4: fdatasync should skip metadata writeout when overwriting

I think fdatasync should skip journal flush in data=ordered and
data=writeback mode when it overwrites to already-instantiated blocks on
HDD. When I_DIRTY_DATASYNC flag is not set, fdatasync should skip journal
writeout because this indicates only atime or/and mtime updates.
Following patch is the same approach of ext2's fsync code(ext2_sync_file).

jbd2: fix possible journal overflow issues
There are several cases where the running transaction can get buffers
added to its BJ_Metadata list which it never dirtied, which makes its
t_nr_buffers counter end up larger than its t_outstanding_credits
counter.
This will cause issues when starting new transactions as while we are
logging buffers we decrement t_outstanding_buffers, so when
t_outstanding_buffers goes negative, we will report that we need less
space in the journal than we actually need, so transactions will be
started even though there may not be enough room for them. In the worst
case scenario (which admittedly is almost impossible to reproduce) this
will result in the journal running out of space.
The fix is to only refile buffers from the committing transaction to the
running transactions BJ_Modified list when b_modified is set on that
journal, which is the only way to be sure if the running transaction has
modified that buffer.
This patch also fixes an accounting error in journal_forget, it is
possible that we can call journal_forget on a buffer without having
modified it, only gotten write access to it, so instead of freeing a
credit, we only do so if the buffer was modified. The assert will help
catch if this problem occurs. Without these two patches I could hit
this assert within minutes of running postmark, with them this issue no
longer arises.

jbd2: fix the way the b_modified flag is cleared
Currently at the start of a journal commit we loop through all of the buffers
on the committing transaction and clear the b_modified flag (the flag that is
set when a transaction modifies the buffer) under the j_list_lock.
The problem is that everywhere else this flag is modified only under the jbd2
lock buffer flag, so it will race with a running transaction who could
potentially set it, and have it unset by the committing transaction.
This is also a big waste, you can have several thousands of buffers that you
are clearing the modified flag on when you may not need to. This patch
removes this code and instead clears the b_modified flag upon entering
do_get_write_access/journal_get_create_access, so if that transaction does
indeed use the buffer then it will be accounted for properly, and if it does
not then we know we didn't use it.
That will be important for the next patch in this series. Tested thoroughly
by myself using postmark/iozone/bonnie++.

Those tuners are currently used only under media/dvb. However,
they can support also analog TV. Better to move them to the same place
as the other hybrid tuners. This would make easier to use those tuners also
by analog drivers.
There were several issues in the past, caused by the hybrid tuner design, since
now, the same tuner can be used by drivers/media/dvb and drivers/media/video.
Kconfig items were rearranged, to split V4L/DVB core from their drivers.
Tuner setup were happening during i2c attach callback. This means that it would
happen on two conditions:
1) if tuner module weren't load, it will happen at request_module("tuner");
2) if tuner is not compiled as a module, or it is already loaded
(for example, on setups with more than one tuner), it will happen
when saa7134 registers I2C bus.
Due to that, if tuner were loaded, tuner setup will happen _before_ reading
the proper values at tuner eeprom. Since set_addr refuses to change for a tuner
that were previously defined (except if the tuner_addr is set), this were
making eeprom tuner detection useless.
This patch removes tuner type setup from saa7134-i2c, moving it to the proper
place, after taking eeprom into account.

i2c: Add support for device alias names
Based on earlier work by Jon Smirl and Jochen Friedrich.
This patch allows new-style i2c chip drivers to have alias names using
the official kernel aliasing system and MODULE_DEVICE_TABLE(). At this
point, the old i2c driver binding scheme (driver_name/type) is still
supported.
