The kernel crashes when ipsec passes a udp packet of about 14XX bytes
of data to aes-xcbc-mac.
It seems the first xxxx bytes of the data are in first sg entry,
and remaining xx bytes are in next sg entry. But we don't
check next sg entry to see if we need to go look the page up.
I noticed in hmac.c, we do a scatterwalk_sg_next(), to do this check
and possible lookup, thus xcbc.c needs to use this routine too.
A 15-hour run of an ipsec stress test sending streams of tcp and
udp packets of various sizes, using this patch and
aes-xcbc-mac completed successfully, so hopefully this fixes the
problem.

firewire: fw-ohci: plug dma memory leak in AR handler

There's an ugly little memory leak in firewire-ohci's
ar_context_tasklet(), where we're not freeing up some of the memory we
use for each ar_buffer, due to a moving pointer. The problem has been
there for a while, but didn't get noticed until after converting the AR
routines over to use coherent DMA and I started running into I/O stall-
outs with the following message output repeatedly to the console:
PCI-DMA: Out of IOMMU space for 53248 bytes at device 0000:04:09.0
Plugging this leak is definitely necessary, but unfortunately, isn't the
entire answer to my problem, it only increases the amount of I/O that I
can do before hitting the problem. Still working on tracking down the
root cause..

The unlazy_fpu() path calls in to save_fpu() if the task has
TIF_USEDFPU set. save_fpu() being the crap API that it is has the side
effect of clearing the flag itself, which presently doesn't happen
if we're using FPU emulation. Fix this up for now, pending an overhaul
in 2.6.26.

Presently with preempt enabled there's the possibility to be preempted
after the TIF_USEDFPU test and the register save, leading to bogus
state post-__switch_to(). Use an explicit preempt_disable()/enable()
pair around unlazy_fpu()/clear_fpu() to avoid this. Follows the x86
change.

Work around the CPU clock miscalculation on Au1000DA/HA/HB due the
sys_cpupll register being write-only, i.e. actually do what the comment
before cal_r4off() function advertised for years but the code failed at.
This is achieved by just giving user a chance to define the clock
explicitly in the board config. via CONFIG_SOC_AU1000_FREQUENCY option,
defaulting to 396 MHz if the option is not given...
The patch is based on the AMD's big unpublished patch, the issue seems to
be an undocumented errata (or feature :-)...

The following patch allows ixp4xx-beeper to be loaded by udev
automatically when compiled as a module with kernel versions 2.4.24
and greater. This patch is required because commit
43cc71eed1250755986da4c0f9898f9a635cb3bf adds "platform:" to the
modalias string.
LKG7102D7:~# udevinfo -a -p /sys/devices/platform/ixp4xx-beeper.4
looking at device '/devices/platform/ixp4xx-beeper.4':
KERNEL=="ixp4xx-beeper.4"
SUBSYSTEM=="platform"
DRIVER==""
ATTR{modalias}=="platform:ixp4xx-beeper"
udev therefore tries to modprobe platform:ixp4xx-beeper instead of
ixp4xx-beeper.

Only request I/O ports 0x295-0x296 instead of the full I/O address
range. This solves a conflict with PNP resources on a few motherboards.
Also request the I/O ports in two parts (4 low ports, 4 high ports)
during device detection, otherwise the PNP resource makes the request
(and thus the detection) fail.

Some time ago it turned out that our suspend code ordering broke some
NVidia-based systems that hung if _PTS was executed with one of the PCI
devices, specifically a USB controller, in a low power state.
Then, it was noticed that the suspend code ordering was not compliant
with ACPI 1.0, although it was compliant with ACPI 2.0 (and later), and
it was argued that the code had to be changed for that reason (ref.
http://bugzilla.kernel.org/show_bug.cgi?id=9528).
So we did, but evidently we did wrong, because it's now turning out that
some systems have been broken by this change. Refs:
http://bugzilla.kernel.org/show_bug.cgi?id=10340
https://bugzilla.novell.com/show_bug.cgi?id=374217#c16
[ I said at that time that something like this might happend, but the
majority of people involved thought that it was improbable due to the
necessity to preserve the compliance of hardware with ACPI 1.0. ]
This actually is a quite serious regression from 2.6.24.
Moreover, the ACPI 1.0 ordering of suspend code introduced another issue
that I have only noticed recently. Namely, if the suspend of one of
devices fails, the already suspended devices will be resumed without
executing _WAK before, which leads to problems on some systems (for
example, in such situations thermal management is broken on my HP
nx6325). Consequently, it also breaks suspend debugging on the affected
systems.
Note also, that the requirement to execute _PTS before suspending
devices does not really make sense, because the device in question may
be put into a low power state at run time for a reason unrelated to a
system-wide suspend.
For the reasons outlined above, the change of the suspend ordering
should be reverted, which is done by the patch below.

https://bugzilla.novell.com/show_bug.cgi?id=374217

Plip uses spin_lock_irq/spin_unlock_irq in its IRQ handler (called from
parport IRQ handler), the latter enables interrupts without parport
subsystem IRQ handler expecting it.
The bug can be seen if you compile kernel with lock dependency checking
and use plip --- it produces a warning.
This patch changes it to spin_lock_irqsave/spin_lock_irqrestore, so that
it doesn't enable interrupts when already disabled.

These messages are a regression compared with 2.6.24, which did not
flood the syslog with them.
The actual underlying problem was introduced in 2.6.23, when somebody
made the string parsing no longer accept nul-terminated strings as a
valid input to store_uevent().
Eg. "add\0" was valid prior to 2.6.23, where the code regressed to
require "add" without the '\0'.
This patch fixes the 2.6.23 / 2.6.24 regressions, by having the code
once again tolerate the trailing '\0', if present.
According to GregKH, this mainly affects older Ubuntu systems, such as
the one I have here that requires this fix.

When getting disconnected we need to release eventual grabs on the
underlying input device as we also release the input device itself.
Otherwise, we would try to release the grab when the client that
requested it closes its handle, accessing the input device which
might already be freed.

This patch fixes bits of the DRM so to make the radeon DRI work on
non-cache coherent PCI DMA variants of the PowerPC processors.
It moves the few places that needs change to wrappers to that
other architectures with similar issues can easily add their
own changes to those wrappers, at least until we have more useful
generic kernel API.

From Kernel BZ 10289 - not sure why anyone would boot an intel with no agp
but it shouldn't crash.

This interface was originally designed wrong, confusing bit-fields and
integers, major brown paper bag going back many years...
But userspace only ever used 4 values so fix the interface for new
users and fix the implementation to deal with the 4 values userspace
has ever emitted (0x1, 0x2, 0x3, 0x6).

There have been reported regressions of the SIL 680 driver when using MMIO, so
this makes it only try MMIO on Cell blades where it's known to be necessary
(the host bridge doesn't do PIO on these).
We'll try to find the root problem with MMIO separately.
