bnx2: Promote vector field in bnx2_irq structure from u16 to unsigned int
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

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.

[XFS] Prevent direct I/O from mapping extents beyond eof
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.

Memory allocations for log->l_grant_trace and iclog->ic_trace are done on

call xlog_trace_iclog() under a spinlock and allocating memory here can

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.

The deadlock happens because ipoib_stop() calls ipoib_ib_dev_down()

which calls ipoib_mcast_leave(). The latter calls
ib_sa_free_multicast(), and this waits until the multicast completion

The problem is that dev->driver_data for a ccw device is NULL,
while it should point to the ccwgroup device it is a member of.
This happened due to incorrect cleanup if creating a ccwgroup
device failed because the ccw devices were already grouped.
Fix this by setting cdev[i] to NULL in the error handling of
ccwgroup_create_from_string() after we give up our reference and
by checking if the driver_data points to the ccwgroup device in
ccwgroup_release() just to be really sure.

udp: Fix rcv socket locking
The previous patch in response to the recursive locking on IPsec
reception is broken as it tries to drop the BH socket lock while in

This patch fixes it by shrinking the section protected by the

the lock is for the accounting which happens in that function.

memstick: fix MSProHG 8-bit interface mode support
- 8-bit interface mode never worked properly. The only adapter I have
which supports the 8b mode (the Jmicron) had some problems with its
clock wiring and they discovered it only now. We also discovered that
ProHG media is more sensitive to the ordering of initialization
commands.
- Make the driver fall back to highest supported mode instead of always
falling back to serial. The driver will attempt the switch to 8b mode
for any new MSPro card, but not all of them support it. Previously,
these new cards ended up in serial mode, which is not the best idea
(they work fine with 4b, after all).

atmel_lcdfb: disable LCD and DMA engines when suspending
When suspending the system with atmel_lcdfb enabled, I sometimes see
this:
atmel_lcdfb atmel_lcdfb.0: FIFO underflow 0x10
Which can be explained by the fact that we're not stopping the LCD
controller and its DMA engine when suspending, we're just gating the
clocks to them.
There's another potential issue which may be harder to trigger but
much more nasty: If we gate the clocks at _just_ the right moment,
e.g. when the DMA engine is doing a bus transaction, we may cause the
DMA engine to violate the system bus protocol and cause a lockup.
Avoid these issues by shutting down the LCD controller before entering
suspend (and restarting it when resuming). This prevents the underrun
from happening in the first place, and prevents whatever nastiness is
happening when the bus clock stops in the middle of a DMA transfer.
