I don't even live in the same country as any of my PA-RISC hardware
these days, so the odds of me touching the code are pretty low.
(Also re-order things to ensure jejb gets CC'd since he's been the
primary maintainer for the last few years.)

There is an issue when memcg unregisters events that were attached to
the same eventfd:
- On the first call mem_cgroup_usage_unregister_event() removes all
events attached to a given eventfd, and if there were no events left,
thresholds->primary would become NULL;
- Since there were several events registered, cgroups core will call
mem_cgroup_usage_unregister_event() again, but now kernel will oops,
as the function doesn't expect that threshold->primary may be NULL.
That's a good question whether mem_cgroup_usage_unregister_event()
should actually remove all events in one go, but nowadays it can't
do any better as cftype->unregister_event callback doesn't pass
any private event-associated cookie. So, let's fix the issue by
simply checking for threshold->primary.
FWIW, w/o the patch the following oops may be observed:

Adapt omap-iommu-debug to the latest omap-iommu API changes, which
were introduced by commit fabdbca "iommu/omap: eliminate the public
omap_find_iommu_device() method".
In a nutshell, iommu users are not expected to provide the omap_iommu
handle anymore - instead, iommus are attached using their user's device
handle.
omap-iommu-debug is a hybrid beast though: it invokes both public and
private omap iommu API, so fix it as necessary (otherwise a crash
is imminent).
Note: omap-iommu-debug is a bit disturbing, as it fiddles with internal
omap iommu data and requires exposing API which is otherwise not needed.
It should better be more tightly coupled with omap-iommu, to prevent
further bit rot and avoid exposing redundant API. Naturally that's out
of scope for the -rc cycle, so for now just fix the obvious.

Marcell Zambo and Janos Farago noticed and reported that when
new conntrack entries are added via netlink and the conntrack table
gets full, soft lockup happens. This is because the nf_conntrack_lock
is held while nf_conntrack_alloc is called, which is in turn wants
to lock nf_conntrack_lock while evicting entries from the full table.
The patch fixes the soft lockup with limiting the holding of the
nf_conntrack_lock to the minimum, where it's absolutely required.
It required to extend (and thus change) nf_conntrack_hash_insert
so that it makes sure conntrack and ctnetlink do not add the same entry
twice to the conntrack table.

From: Ben Hutchings <ben@decadent.org.uk>
Extended VBLKs (those larger than the preset VBLK size) are divided
into fragments, each with its own VBLK header. Our LDM implementation
generally assumes that each VBLK is contiguous in memory, so these
fragments must be assembled before further processing.
Currently the reassembly seems to be done quite wrongly - no VBLK
header is copied into the contiguous buffer, and the length of the
header is subtracted twice from each fragment. Also the total
length of the reassembled VBLK is calculated incorrectly.

This patch fixes a regression that was introduced by
commit 0a5f38467765ee15478db90d81e40c269c8dda20
davinci_emac: Add Carrier Link OK check in Davinci RX Handler
Said commit adds a check whether the carrier link is ok. If the link is
not ok, the skb is freed and no new dma descriptor added to the rx dma
channel. This causes trouble during initialization when the carrier
status has not yet been updated. If a lot of packets are received while
netif_carrier_ok returns false, all dma descriptors are freed and the
rx dma transfer is stopped.
The bug occurs when the board is connected to a network with lots of
traffic and the ifconfig down/up is done, e.g., when reconfiguring
the interface with DHCP.
The bug can be reproduced by flood pinging the davinci board while doing
ifconfig eth0 down
ifconfig eth0 up
on the board.
After that, the rx path stops working and the overrun value reported
by ifconfig is counting up.
This patch reverts commit 0a5f38467765ee15478db90d81e40c269c8dda20
and instead issues warnings only if cpdma_chan_submit returns -ENOMEM.

With kernel 3.1, Christoph removed i_alloc_sem and replaced it with
calls (namely inode_dio_wait() and inode_dio_done()) which are
EXPORT_SYMBOL_GPL() thus they cannot be used by non-GPL file systems and
further inode_dio_wait() was pushed from notify_change() into the file
system ->setattr() method but no non-GPL file system can make this call.
That means non-GPL file systems cannot exist any more unless they do not
use any VFS functionality related to reading/writing as far as I can
tell or at least as long as they want to implement direct i/o.
Both Linus and Al (and others) have said on LKML that this breakage of
the VFS API should not have happened and that the change was simply
missed as it was not documented in the change logs of the patches that
did those changes.
This patch changes the two function exports in question to be
EXPORT_SYMBOL() thus restoring the VFS API as it used to be - accessible
for all modules.
Christoph, who introduced the two functions and exported them GPL-only
is CC-ed on this patch to give him the opportunity to object to the
symbols being changed in this manner if he did indeed intend them to be
GPL-only and does not want them to become available to all modules.

The code for ip1001_config_init() was totally broken if you were not
using RGMII. Instead of returning an error code or zero it actually
returned the value in the IP1001_SPEC_CTRL_STATUS_2 register. It was
also trying to set the IP1001_APS_ON bit , but never actually wrote
back the register.
The error checking was also incorrect in both this function and the

According to i.MX27 Reference Manual (p 1593) TXBIT0 bit selects
whether the most significant or the less significant part of the
data word written to the FIFO is transmitted.
As DSP_A is the same as DSP_B with a data offset of 1 bit, it
doesn't make any sense to remove TXBIT0 bit here.

The code is currently always checking the first resource of every
device only (several times.) This has been broken since the ACPI check
was added in February 2010 in commit
91fedede0338eb6203cdd618d8ece873fdb7c22c.
Fix the check to run on each resource individually, once.

When doing IO with large amounts of data fragmentation, the global block
reserve calulations are too low. This increases them to avoid
ENOSPC crashes.

If btrfs reads a block and finds a parent transid mismatch, it clears
the uptodate flags on the extent buffer, and the pages inside it. But
we only clear the uptodate bits in the state tree if the block straddles
more than one page.
This is from an old optimization from to reduce contention on the extent
state tree. But it is buggy because the code that retries a read from
a different copy of the block is going to find the uptodate state bits
set and skip the IO.
The end result of the bug is that we'll never actually read the good
copy (if there is one).
The fix here is to always clear the uptodate state bits, which is safe
because this code is only called when the parent transid fails.

When we are setting up the mount, we close all the
devices that were not actually part of the metadata we found.
But, we don't make sure that one of those devices wasn't
fs_devices->latest_bdev, which means we can do a use after free
on the one we closed.
This updates latest_bdev as it goes.
