The multiple headphone pins are usually handled as copied from the same
source, not as individual channels like front and surround. Thus it'd
be more correct to avoid the channel suffix for "Headphone" pin labels
in snd_hda_get_pin_label() but give an index number instead.

When the manager is running non-secure, the only channels that can
issue interrupts are the ones that have a 1 in their corresponding bit
in Configuration Register 3. The other ones will generate an abort
when trying to signal the end of the transaction so they are useless
in non-secure mode.

The Kconfig options for the PL310 errata workarounds do not use a
consistent naming scheme for either the config option or the bool
description.
This patch tidies up the options by ensuring that the bool descriptions
are prefixed with "PL310 errata:" and the config options are prefixed
with PL310_ERRATA_, making it much clearer in menuconfig as to what the
workarounds are for.

This patch implements a workaround for PL310 erratum 769419. On
revisions of the PL310 prior to r3p2, the Store Buffer does not
automatically drain. This can cause normal, non-cacheable writes to be
retained when the memory system is idle, leading to suboptimal I/O
performance for drivers using coherent DMA.
This patch adds an optional wmb() call to the cpu_idle loop. On systems
with an outer cache, this causes an explicit flush of the store buffer.

This patch is a revision of the one I previously posted.
I tried to integrate all the suggestions Steve gave.
The purpose of the patch is to change function gfs2_alloc_block
(allocate either a dinode block or an extent of data blocks)
to a more generic gfs2_alloc_blocks function that can
allocate both a dinode _and_ an extent of data blocks in the
same call. This will ultimately help us create a multi-block
reservation scheme to reduce file fragmentation.
This patch moves more toward a generic multi-block allocator that
takes a pointer to the number of data blocks to allocate, plus whether
or not to allocate a dinode. In theory, it could be called to allocate
(1) a single dinode block, (2) a group of one or more data blocks, or
(3) a dinode plus several data blocks.

Add sync of metadata after fallocate for O_SYNC files to ensure that we
meet expectations for everything being on disk in this case.
Unfortunately, the offset and len parameters are modified during the
course of the fallocate function, so I've had to add a couple of new
variables to call generic_write_sync() at the end.
I know that potentially this will sync data as well within the range,
but I think that is a fairly harmless side-effect overall, since we
would not normally expect there to be any dirty data within the range in
question.

The poodle restart handler was added in 74617fb6b8 (3593/1: Add reboot
and shutdown handlers for Zaurus handhelds), and at that time it was
necessary to deal with the RCSR register. This commit also forced all
restarts to use the 'hard' restart method.
In dc38e2ad53 (pxa: Fix RCSR handling), the RCSR handling was removed,
leaving just the forcing to use a 'hard' restart. As hard restarts are
the default (in the absense of a reboot= command line argument), this
seems pointless. In any case, Richard Purdie says:

We only need to set the system up for a soft-restart if we're going to
be doing a soft-restart. Provide a new function (soft_restart()) which
does the setup and final call for this, and make platforms use it.
Eliminate the call to setup_restart() from the default handler.
This means that platforms arch_reset() function is no longer called with
the page tables prepared for a soft-restart, and caches will still be
enabled.

Some later SEC v3.x are equipped with a second IRQ line.
By correctly assigning IRQ affinity, this feature can be
used to increase performance on dual core parts, like the
MPC8572E and P2020E.
The existence of the 2nd IRQ is determined from the device
node's interrupt property. If present, the driver remaps
two of four channels, which in turn makes those channels
trigger their interrupts on the 2nd line instead of the first.
To handle single- and dual-IRQ combinations efficiently,
talitos gets two new interrupt handlers and back-half workers.

Fixed up to not register HMAC algorithms on sec2.0 devices.
Rationale (from Lee):
on an 8349E Rev1.1, there's a problem with hmac for any talitos
hmac sequence requiring an intermediate hash context (Pointer
DWORD 1); the result is an incorrect hmac. An intermediate hash
context is required for something longer than (65536-blocksize),
and for other cases when update/finup/final are used inefficiently.
Interestingly, a normal hash (without hmac) works perfectly
when using an intermediate context.

To prevent an NFS server from being used to create a directory loop in an NFS
superblock on the client, the following patch was committed:
commit 1836750115
Author: Al Viro <viro@zeniv.linux.org.uk>
Date: Tue Jul 12 21:42:24 2011 -0400
Subject: fix loop checks in d_materialise_unique()
This causes ELOOP to be reported to anyone trying to access the dentry that
would otherwise cause the kernel to complete the loop.
However, no indication is given to the caller as to why an operation that ought
to work doesn't. The fault is with the kernel, which doesn't want to try and
solve the problem as it gets horrendously messy if there's another mountpoint
somewhere in the trees being spliced that can't be moved[*].
[*] The real problem is that we don't handle the excision of a subtree that
gets moved _out_ of what we can see. This can happen on the server where a
directory is merely moved between two other dirs on the same filesystem, but
where destination dir is not accessible by the client.
So, given the choice to return ELOOP rather than trying to reconfigure the
dentry tree, we should give the caller some indication of why they aren't being
allowed to make what should be a legitimate request and log a message.
