This adds support to GFS2 for selinux extended attributes. There is a
known bug in gfs2_ea_get() which is believed to be independant of this
patch. Further patches will follow once that bug is fixed in order to
make GFS2 use as much of the generic eattr infrastructure as possible.

Setup the lock_dlm kobject before setting up the dlm lockspace instead
of after. We want to use the sysfs files to detect the mount without
having to wait for the dlm setup which can take a while.

This adds some extra debugging to glock.c and changes
inode.c's deallocation code to call the debugging code
at a suitable moment. I'm chasing down a particular bug
to do with deallocation at the moment and the code can
go again once the bug is fixed.
Also this includes the first part of some changes to unify
the Linux struct inode and GFS2's struct gfs2_inode. This
transformation will happen in small parts over the next short
period.

This patch drops the log spinlock when an I/O error occurs
to avoid any possible problems in case of blocking or

The original code ordered the blocks allocated in the build_height
routine backwards causing excessive disk seeks during a read of the
metadata. This patch reverses the order to try and reduce disk seeks.
Example: A five level metadata tree, I = Inode, P = Pointers, D = Data
You need to read the blocks in the order:
I P5 P4 P3 P2 P1 D
in order to read a single data block. The new code now orders the blocks
in this way. The old code used to order them as:
I P1 P2 P3 P4 P5 D
requiring two extra seeks on average. Note that for files which are
grown by gradual extension rather than by truncate or by llseek/write
at a large offset, this doesn't apply. In the case of writing to a
file linearly, this routine will only be called upon to extend the
height of the tree by one block at a time, so the ordering is
determined by when its called rather than by the internals of the
routine itself. Optimising that part of the ordering is a much
harder problem.

A bug report from Gerd Hoffmann has highlighted that unconditionally
enabling the transmit interrupt at the end of console writes is very
bad.
In Gerd's case, it causes the test for buggy UARTs to give false
positives, incorrectly identifying ports as buggy when they are not.
Moreover, if we unconditionally enable the interrupt, and the port
is sharing it's interrupt with other ports, there is the very real
possibility that we'll cause an interrupt storm. (Not all ports use
OUT2 as an interrupt mask.)
Hence, revert part of f91a3715db2bb44fcf08cec642e68f919b70f7f4 and
all of f5968b37b3ad35b682b574b578843a0361218aff until a better solution
can be found.

The locking for the uart_port is over complicated, and can be
simplified if we introduce a flag to indicate that a port is "dead"
and will be removed.
This also helps the validator because it removes a case of non-nested

The last step of netdevice registration was being done by a delayed
call, but because it was delayed, it was impossible to return any error
code if the class_device registration failed.
Side effects:
* one state in registration process is unnecessary.
* register_netdevice can sleep inside class_device registration/hotplug
* code in netdev_run_todo only does unregistration so it is simpler.

tg3_run_loopback doesn't check that dev_alloc_skb() returns anything
useful.
Even if dev_alloc_skb() fails to return an skb to us we'll happily go
on and assume it did, so we risk dereferencing a NULL pointer. Much
better to fail gracefully by returning -ENOMEM than crashing here.

The test used in the linkwatch does not handle wrap-arounds correctly.
Since the intention of the code is to eliminate bursts of messages we
can afford to delay things up to a second. Using that fact we can
easily handle wrap-arounds by making sure that we don't delay things
by more than one second.
This is based on diagnosis and a patch by Stefan Rompf.

A race condition exists in mptfc between the thread registering a device
with the fc transport and the scan work generated by the transport.
This race existed prior to the application of the mptfc bug fix patch.
mptfc_register_dev() calls fc_remote_port_add() with the FC_RPORT_ROLE_TARGET
bit set in the rport ids passed to the function. Having this bit set causes
fc_remote_port_add() to schedule a scan of the device.
This scan can execute before mptfc_register_dev() can fill in the dd_data
in the rport structure. When this happens, mptfc_target_alloc() will fail
because dd_data is null.
Attached is a patch which fixes the problem. The patch changes the rport ids
passed to fc_remote_port_add() to not have the TARGET bit set. This prevents
the scan from being scheduled. After mptfc_register_dev() fills in the rport
dd_data field, fc_remote_port_rolechg() is called, changing the role of the
rport to TARGET. Thus, the scan is scheduled after dd_data is filled
in which prevents the failure in mptfc_target_alloc().

Several structs in <scsi/srp.h> get padded to a multiple of 8 bytes on
64-bit architectures and end up with a size that does not match the
definition in the SRP spec:
SRP spec 64-bit
sizeof (struct indirect_buf) 20 24
sizeof (struct srp_login_rsp) 52 56
sizeof (struct srp_rsp) 36 40
Fix this by adding __attribute__((packed)) to the offending structs.
