Fixed up trivial conflicts:

converted to <asm-generic/socket.h> in the x86 tree. The generic
header has the same new #define's, so that works out fine.
- drivers/net/tun.c
fix conflict between 89f56d1e9 ("tun: reuse struct sock fields") that
switched over to using 'tun->socket.sk' instead of the redundantly
available (and thus removed) 'tun->sk', and 2b980dbd ("lsm: Add hooks
to the TUN driver") which added a new 'tun->sk' use.

When we close a file, we remove preallocated blocks from it. But this
truncation was not protected by i_mutex and thus it could have raced with a
write through a different fd and cause crashes or even filesystem corruption.

So far we preallocated blocks also for directories but that brings a
problem, when to get rid of preallocated blocks we don't need. So far
we removed them in udf_clear_inode() which has a disadvantage that
1) blocks are unavailable long after writing to a directory finished
and thus one can get out of space unnecessarily early
2) releasing blocks from udf_clear_inode is problematic because VFS
does not expect us to redirty inode there and it also slows down
memory reclaim.
So preallocate blocks only for regular files where we can drop preallocation
in udf_release_file.

Actually, nilfs is NOT a filesystem came from other operating systems,
but a filesystem created purely for Linux. Nor is it a flash
filesystem but that for generic block devices.
So, this moves nilfs outside the misc category as I responded in LKML

The nilfs_bmap_lookup() is now a wrapper function of
nilfs_bmap_lookup_at_level().
This moves the nilfs_bmap_lookup() to a header file converting it to
an inline function and gives an opportunity for optimization.

The current btree code is written so that btree functions call dat
operations via wrapper functions in bmap.c when they allocate, free,
or modify virtual block addresses.
This abstraction requires additional function calls and causes
frequent call of nilfs_bmap_get_dat() function since it is used in the
every wrapper function.
This removes the wrapper functions and makes them available from
btree.c and direct.c, which will increase the opportunity of
compiler optimization.

This is a preparation for the successive cleanup ("nilfs2: allow btree

Even though many btree functions take a btree object as their first
argument, most of them are not used in their functions.
This sticky use of the btree argument is hurting code readability and
giving the possibility of inefficient code generation.
So, this removes the unnecessary btree arguments.

This is a re-revised patch to shorten freeze period.
This version include a fix of the bug Konishi-san mentioned last time.
When GC is runnning, GC moves live block to difference segments.
Copying live blocks into memory is done in a transaction,
however it is not necessarily to be in the transaction.
This patch will get the nilfs_ioctl_move_blocks() out from
transaction lock and put it before the transaction.
I ran sysbench fileio test against nilfs partition.
I copied some DVD/CD images and created snapshot to create live blocks
before starting the benchmark.
Followings are summary of rc8 and rc8 w/ the patch of per-request
statistics, which is min/max and avg. I ran each test three times and
bellow is average of those numers.
According to this benchmark result, average time is slightly degrated.
However, worstcase (max) result is significantly improved.
This can address a few seconds write freeze.

This removes nilfs_write_super and commit super block in nilfs
internal thread, instead of periodic write_super callback.
VFS layer calls ->write_super callback periodically. However,
it looks like that calling back is ommited when disk I/O is busy.
And when cleanerd (nilfs GC) is runnig, disk I/O tend to be busy thus
nilfs superblock is not synchronized as nilfs designed.
To avoid it, syncing superblock by nilfs thread instead of pdflush.

This removes redundant super block commit.
nilfs_write_super will call nilfs_commit_super to store super block
into block device. However, nilfs_put_super will call
nilfs_commit_super right after calling nilfs_write_super. So calling
nilfs_write_super in nilfs_put_super would be redundant.

The current metadata file code skips disk address lookup for its data
block if the buffer has a mapped flag.
This has a potential risk to cause read request to be performed
against the stale block address that GC moved, and it may lead to meta
data corruption. The mapped flag is safe if the buffer has an
uptodate flag, otherwise it may prevent necessary update of disk
address in the next read.
This will avoid the potential problem by ensuring disk address lookup
before reading metadata block even for buffers with the mapped flag.

This patch uses a reader/writer semaphore instead of the own lock and
kills this warning.

Unlike on most other architectures ino_t is an unsigned int on s390.
So add an explicit cast to avoid this compile warning:
fs/nilfs2/recovery.c: In function 'recover_dsync_blocks':
fs/nilfs2/recovery.c:555: warning: format '%lu' expects type 'long unsigned int', but argument 3 has type 'ino_t'

The __nilfs_read_inode function is ignoring the error code returned
from nilfs_read_inode_common(), and wrongly delivers a success code
(zero) when it escapes from the function in erroneous cases.
This adds the missing error handling.

Redesign tx timeout handling in line with new firmware
reset design that co-ordinates with other PCI function
drivers.
o For NX3031, first try to reset PCI function's own
context before requesting firmware reset.
o For NX2031, since firmware heartbit is not supported
directly request firmware reset.

o Access on card memory through memory controller (agent)
rather than moving small pci window around. Clean up the
code for moving windows around.
o Restrict memory accesss to 64 bit, currently only firmware
download uses this.

Use 8 byte strides for firmware download into card
memory since oncard memory controller needs 8 byte
(64 bit) accesses. This avoids unnecessary rmw cycles.
