"start + num_bytes >= actual_end" can happen when compressed page writeback races
with file truncation. In that case we need unlock and release pages past the end

Not being able to delete an orphan item isn't a horrible thing. The worst that
happens is the next time around we try and do the orphan cleanup and we can't
find the referenced object and just delete the item and move on.

I noticed that one of the post-2.6.36 patches broke runtime PM of the
r8169 on my MSI Wind test machine in such a way that the link was not
brought up after reconnecting the network cable.
In the process of debugging the issue I realized that we only should
invoke the runtime PM functions in rtl8169_check_link_status() when
link change is reported and if we do so, the problem goes away.
Moreover, this allows rtl8169_runtime_idle() to be simplified quite
a bit.

After a few unsuccessful NFS mount attempts in which the client and
server cannot agree on an authentication flavor both support, the
client panics. nfs_umount() is invoked in the kernel in this case.
Turns out nfs_umount()'s UMNT RPC invocation causes the RPC client to
write off the end of the rpc_clnt's iostat array. This is because the
mount client's nrprocs field is initialized with the count of defined
procedures (two: MNT and UMNT), rather than the size of the client's
proc array (four).
The fix is to use the same initialization technique used by most other
upper layer clients in the kernel.
Introduced by commit 0b524123, which failed to update nrprocs when
support was added for UMNT in the kernel.

There is definitly a problem, that some option cards send up broken
IP pakets leading to corrupted IP packets. These corruptions aren't
detected, because the driver claims that the packets are already
checksummed. This change removes the CHECKSUM_UNNECESSARY option
and let IP detect broken data.

A while back I made some changes to enable netpoll in the bonding driver. Among
them was a per-cpu flag that indicated we were in a path that held locks which
could cause the netpoll path to block in during tx, and as such the tx path
should queue the frame for later use. This appears to have given rise to a
regression. If one of those paths on which we hold the per-cpu flag yields the
cpu, its possible for us to come back on a different cpu, leading to us clearing
a different flag than we set. This results in odd netpoll drops, and BUG
backtraces appearing in the log, as we check to make sure that we only clear set
bits, and only set clear bits. I had though briefly about changing the
offending paths so that they wouldn't sleep, but looking at my origional work
more closely, it doesn't appear that a per-cpu flag is warranted. We alrady
gate the checking of this flag on IFF_IN_NETPOLL, so we don't hit this in the
normal tx case anyway. And practically speaking, the normal use case for
netpoll is to only have one client anyway, so we're not going to erroneously
queue netpoll frames when its actually safe to do so. As such, lets just
convert that per-cpu flag to an atomic counter. It fixes the rescheduling bugs,
is equivalent from a performance perspective and actually eliminates some code
in the process.
Tested by the reporter and myself, successfully

commit 0d8e2d0dad98a693bad88aea6876ac8b94ad95c6 (OMAP2+: PM/serial:
hold console semaphore while OMAP UARTs are disabled) added use of the
console semaphore to protect UARTs from being accessed after disabled
during idle, but this causes problems in suspend.
During suspend, the console semaphore is acquired by the console
suspend method (console_suspend()) so the try_acquire_console_sem()
will always fail and suspend will be aborted.
To fix, introduce a check so the console semaphore is only attempted
during idle, and not during suspend. Also use the same check so that
the console semaphore is not prematurely released during resume.
Thanks to Paul Walmsley for suggesting adding the same check during
resume.

Kernel was failing to boot on omap1611 based OSK boards due to
mis-configured SRAM size. Existing code was using a hard-coded value
for 250k, which was then rounded down by PAGE_SIZE. Increasing this to
256k allows kernel to boot on omap1611 SoCs.
Problem reported by and initial fix suggested by Tim Bird.
Thanks to Tony Lindgren for helping diagnose the problem to being
specific to OMAP1611 and not affecting OMAP1610/OMAP1623.

Now that we don't mark VFS inodes dirty anymore for internal
timestamp changes, but rely on the transaction subsystem to push
them out, we need to explicitly log the source inode in rename after
updating it's timestamps to make sure the changes actually get
forced out by sync/fsync or an AIL push.
We already account for the fourth inode in the log reservation, as a
rename of directories needs to update the nlink field, so just
adding the xfs_trans_log_inode call is enough.
This fixes the xfsqa 065 regression introduced by:
"xfs: don't use vfs writeback for pure metadata modifications"

PCI_DEVICE_ID_CISSF is defined as 323b in pci_ids.h but redefined as 3fff in
hpsa.c. The ID of 3fff will _never_ ship as a standalone controller. It is
intended only as part a complete storage solution. As such, this patch
removes the redefinition and the StorageWorks P1210m from the product table.
It also removes a duplicate line for the "unknown" controller support.

Fix two bugs with the port array setup.
The first bug will only show up with broken xHCI hosts with Extended
Capabilities registers that have duplicate port speed entries for the same
port. The idea with the original code was to set the port_array entry to
-1 if the duplicate port speed entry said the port was a different speed
than the original port speed entry. That would mean that later, the port
would not be exposed to the USB core. Unfortunately, I forgot a continue
statement, and the port_array entry would just be overwritten in the next
line.
The second bug would happen if there are conflicting port speed registers
(so that some entry in port_array is -1), or one of the hardware port
registers was not described in the port speed registers (so that some
entry in port_array is 0). The code that sets up the usb2_ports array
would accidentally claim those ports. That wouldn't really cause any
user-visible issues, but it is a bug.
This patch should go into the stable trees that have the port array and
USB 3.0 port disabling prevention patches.

Currently if the space cache inode generation number doesn't match the
generation number in the space cache header we will just fail to load the space
cache, but we won't mark the space cache as an error, so we'll keep getting that
error each time somebody tries to cache that block group until we actually clear
the thing. Fix this by marking the space cache as having an error so we only
get the message once. This patch also makes it so that we don't try and setup
space cache for a block group that isn't cached, since we won't be able to write
it out anyway. None of these problems are actual problems, they are just
annoying and sub-optimal. Thanks,

The error handler is using the test cmd->serial_number == 0 in the
abort routines to signal that the command to be aborted has already
completed normally. This design was to close a race window in the
original error handler where a command could go through the normal
completion routines after it timed out but before error handling was
started.
Mike Anderson pointed out that when we converted our timeout and
softirq completions, we picked up atomicity here because the block
layer now mediates this with the REQ_ATOM_COMPLETE flag and guarantees
that *either* the command times out or our done routine is called, but
ensures we can't get both occurring. That makes the serial number
zero check redundant and it can be removed.

Firmware requires a larger configuration entry size than the driver
currently allows, and MSI-X pretty much doesn't work with current FW,
so disable it for now.

This patch corrects an issue in bsg that results in a general protection
fault if an LLD is removed while an application is using an open file
handle to a bsg device, and the application issues an ioctl. The fault
occurs because the class_dev is NULL, having been cleared in
bsg_unregister_queue() when the driver was removed. With this
patch, a check is made for the class_dev, and the application
will receive ENXIO if the related object is gone.

The "e" pointer is either NULL or freed when we call
drm_vblank_put(dev, e->pipe) on the error path. Just pass the "pipe"
variable directly instead.
I changed another caller to use "pipe" as well for consistency.
