There is an nmi_enter() call without an nmi_exit().
This can't be correct, it breaks rcu (at least the preempt version) and

On AVR32, all parameters beyond the 5th are passed on the stack. System
calls don't use the stack -- they borrow a callee-saved register
instead. This means that syscalls that take 6 parameters must be called
through a stub that pushes the last parameter on the stack.

When two md arrays share some block device (e.g each uses different
partitions on the one device), a resync of one array will wait for
the resync on the other to finish.
This can be a long time and as it currently waits TASK_UNINTERRUPTIBLE,
the softlockup code notices and complains.

The bnx2 driver stores/uses the irq value from the pci_dev internally.
But when it stores the irq value, it has been performing an
integer demotion. Because of the recent changes made to
arch/x86/kernel/io_apic.c, the new method in creating the irq value
(using build_irq_for_pci_dev()) has exposed this bug on x86 systems.
Because of this demotion when calling request_irq() from
bnx2_request_irq(), the driver would get a return code of -EINVAL.
This is because the kernel could not find the requested irq descriptor.
By storing the irq value properly, the kernel can find the correct
irq descriptor and the bnx2 driver can operate normally.

If INIT-ACK is received with SupportedExtensions parameter which
indicates that the peer does not support AUTH, the packet will be
silently ignore, and sctp_process_init() do cleanup all of the
transports in the association.
When T1-Init timer is expires, OOPS happen while we try to choose
a different init transport.
The solution is to only clean up the non-active transports, i.e
the ones that the peer added. However, that introduces a problem
with sctp_connectx(), because we don't mark the proper state for
the transports provided by the user. So, we'll simply mark
user-provided transports as ACTIVE. That will allow INIT
retransmissions to work properly in the sctp_connectx() context
and prevent the crash.

When unreserving space with boundaries that are not block aligned we round
up the start and round down the end boundaries and then use this function,
xfs_zero_remaining_bytes(), to zero the parts of the blocks that got
dropped during the rounding. The problem is we don't consider if these
blocks are beyond eof. Worse still is if we encounter delayed allocations
beyond eof we will try to use the magic delayed allocation block number as
a real block number. If the file size is ever extended to expose these
blocks then we'll go through xfs_zero_eof() to zero them anyway.

We have a use-after-free issue where log completions access buffers via
the buffer log item and the buffer has already been freed. Fix this by
taking a reference on the buffer when attaching the buffer log item and
release the hold when the buffer log item is detached and we no longer
need the buffer. Also create a new function xfs_buf_item_free() to combine
some common code.

If we call xfs_lock_two_inodes() to grab both the iolock and the ilock,
then drop the ilocks on both inodes, then grab them again (as
xfs_swap_extents() does) then lockdep will report a locking order problem.
This is a false positive.
To avoid this, disallow xfs_lock_two_inodes() fom locking both inode locks
at once - force calers to make two separate calls. This means that nested
dropping and regaining of the ilocks will retain the same lockdep subclass
and so lockdep will not see anything wrong with this code.

With the help from some tracing I found that we try to map extents beyond
eof when doing a direct I/O read. It appears that the way to inform the
generic direct I/O path (ie do_direct_IO()) that we have breached eof is
to return an unmapped buffer from xfs_get_blocks_direct(). This will cause
do_direct_IO() to jump to the hole handling code where is will check for
eof and then abort.
This problem was found because a direct I/O read was trying to map beyond
eof and was encountering delayed allocations. The delayed allocations
beyond eof are speculative allocations and they didn't get converted when
the direct I/O flushed the file because there was only enough space in the
current AG to convert and write out the dirty pages within eof. Note that
xfs_iomap_write_allocate() wont necessarily convert all the delayed
allocation passed to it - it will return after allocating the first extent
- so if the delayed allocation extends beyond eof then it will stay that
way.

Logically we would return an error in xfs_fs_remount code to prevent users
from believing they might have changed mount options using remount which
can't be changed.
But unfortunately mount(8) adds all options from mtab and fstab to the
mount arguments in some cases so we can't blindly reject options, but have
to check for each specified option if it actually differs from the
currently set option and only reject it if that's the case.
Until that is implemented we return success for every remount request, and
silently ignore all options that we can't actually change.

Memory allocations for log->l_grant_trace and iclog->ic_trace are done on
demand when the first event is logged. In xlog_state_get_iclog_space() we
call xlog_trace_iclog() under a spinlock and allocating memory here can
cause us to sleep with a spinlock held and deadlock the system.
For the log grant tracing we use KM_NOSLEEP but that means we can lose
trace entries. Since there is no locking to serialize the log grant
tracing we could race and have multiple allocations and leak memory.
So move the allocations to where we initialize the log/iclog structures.
Use KM_NOFS to avoid recursing into the filesystem and drop log->l_trace
since it's not even used.
