This attached patch was originally proposed by Anssi Hannula to the dvb-kernel
user to choose the default broadcast mode when using the ttpci driver.
NTSC users need to only add the following line to modprobe.d:
options dvb-ttpci tv_standard=1
PAL users will not need to change anything, for this will be the default.

- Issue a warning when more than 80% of the DMA buffer is being used
(probably due to bad IRQ latency). Warnings are rate-limited.
- Introduce a new parameter 'bufsize' (in KByte) which increases the

It should be V4L2_TUNER_MODE_LANG1_LANG2. What the code does is check if
we are NTSC and a SAP channel is available. If so, then the msp3400
should switch to standard 0x21 if the user wants to hear the SAP
channel, which is for audio modes LANG2 (aka SAP) and LANG1_LANG2
(bilingual).
In the msp3400 driver STEREO is abused for bilingual in PAL. Bilingual
never worked with NTSC in the past and I decided that I'd better not
use the bad PAL example.

The FWSEND parameter controls the size of the firmware chunks sent
down the I2C bus to the chip. Previously this had been set to 1024
but unfortunately some I2C implementations can't transfer data in such
big gulps. Specifically, the pvrusb2 driver has a hard limit of
around 60 bytes, due to the encapsulation there of I2C traffic into
USB messages. So we have to significantly reduce this parameter.

Fixes Samba bug 3621 and kernel.org bug 6147
For servers which require SMB/CIFS packet signing, we were sending the
wrong signature (all zeros) on SMB Read request. The new cifs routine
to do signatures across an iovec was not complete - and SMB Read, unlike
the new SMBWrite2, did not fall back to the older routine (ie use
SendReceive vs. the more efficient SendReceive2 ie used the older
cifs_sign_smb vs. the disabled cifs_sign_smb2) for calculating signatures.
This finishes up cifs_sign_smb2/cifs_calc_signature2 so that the callers
of SendReceive2 can get SMB/CIFS packet signatures.
Now that cifs_sign_smb2 is supported, we could start using it in
the write path but this smaller fix does not include the change
to use SMBWrite2 when signatures are required (which when enabled
will make more Writes more efficient and alloc less memory).
Currently Write2 is only used when signatures are not
required at the moment but after more testing we will enable
that as well).
Thanks to James Slepicka and Sam Flory for initial investigation.

Commit 70674f95c0:
[PATCH] Optimize select/poll by putting small data sets on the stack
resulted in the poll stack being 4-byte aligned on 64-bit architectures,
causing misaligned accesses to elements in the array.
This patch fixes it by declaring the stack in terms of 'long' instead
of 'char'.
Force alignment of poll and select stacks to long to avoid unaligned
access on 64 bit architectures.

The attached patch documents the Linux kernel's memory barriers.
I've updated it from the comments I've been given.
The per-arch notes sections are gone because it's clear that there are so many
exceptions, that it's not worth having them.
I've added a list of references to other documents.
I've tried to get rid of the concept of memory accesses appearing on the bus;
what matters is apparent behaviour with respect to other observers in the
system.
Interrupts barrier effects are now considered to be non-existent. They may be
there, but you may not rely on them.
I've added a couple of definition sections at the top of the document: one to
specify the minimum execution model that may be assumed, the other to specify
what this document refers to by the term "memory".
I've made greater mention of the use of mmiowb().
I've adjusted the way in which caches are described, and described the fun
that can be had with cache coherence maintenance being unordered and data
dependency not being necessarily implicit.
I've described (smp_)read_barrier_depends().
I've rearranged the order of the sections, so that memory barriers are
discussed in abstract first, and then described the memory barrier facilities
available on Linux, before going on to more real-world discussions and examples.
I've added information about the lack of memory barriering effects with atomic
ops and bitops.
I've added information about control dependencies.
I've added more diagrams to illustrate caching interactions between CPUs.
