Using PCIE advanced error recovery stuff creates more user problems than it's worth.
The AER stuff depends on MMCONFIG and in many configurations it just doesn't work.
Plus it doesn't add any real functionality to the driver. The sky2
driver handles its own errors fine as is.
sky2: revert to access PCI config via device space
Using the hardware window into PCI config space is more reliable
and smaller/faster than using the pci_config routines. It avoids issues
with MMCONFIG etc.

x86/paravirt: revert exports to restore old behaviour
Subdividing the paravirt_ops structure caused a regression in certain

Christoph Hellwig objects to this patch on the grounds that modules
shouldn't be using these operations anyway. I don't think this is a
particularly good reason to reject the patch, for several reasons:
1. These operations are still available to modules when not using
CONFIG_PARAVIRT, since they are implicitly exported as inline
functions via the kernel headers. Exporting the same functionality as
GPL-only symbols just adds a gratuitious difference between
CONFIG_PARAVIRT and non-CONFIG_PARAVIRT configurations. If we really
think these operations are not for module use (or non-GPL module use),
then we should solve the problem in a general way.
2. It's a regression from previous kernels, which would work these
modules even with CONFIG_PARAVIRT enabled.
3. The operations in question seem pretty reasonable for modules to
use. The control registers/MSRs can be accessed directly anyway, so there's
no benefit in preventing modules from using standard interfaces. And it seems
reasonable to allow a graphics driver to create its own mappings if it wants.
Therefore, I think this patch should go in for 2.6.24. If people
really think that these operations should not be available to modules,
then we can address that separately.

ACPI uses NR_CPUS in various loops and in some it accesses per cpu data of
processors that are not present(!) and that will never be present.
The pointers to per cpu data are typically not initialized for processors
that are not present. So we seem to be reading something here from offset
0 in memory.
Make ACPI use nr_cpu_ids instead. That stops at the end of the possible
processors.
Convert one loop to NR_CPUS to use the cpu_possible map instead. That way
ranges of processor that can never be brought online are skipped during the

The cause was forgetting to restart the tick after waking up from sleep.
It was disabled before sleeping, and the remaining time used as the

This is done by introducing after_sleep_interval, which is empty in the

An unprivileged process must be able to kill a setuid root program started
by the same user. This is legacy behavior needed for instance for xinit to
kill X when the window manager exits.
When an unprivileged user runs a setuid root program in !SECURE_NOROOT
mode, fP, fI, and fE are set full on, so pP' and pE' are full on. Then
cap_task_kill() prevents the user from signaling the setuid root task.
This is a change in behavior compared to when
!CONFIG_SECURITY_FILE_CAPABILITIES.
This patch introduces a special check into cap_task_kill() just to check
whether a non-root user is signaling a setuid root program started by the
same user. If so, then signal is allowed.

dmaengine: correct invalid assumptions in the Kconfig text
This patch corrects recently changed (and now invalid) Kconfig descriptions
for the DMA engine framework:
- Non-Intel(R) hardware also has DMA engines;
- DMA is used for more than memcpy and RAID offloading.
In fact, on most platforms memcpy and RAID aren't factors, and DMA
exists so that peripherals can transfer data to/from memory while
the CPU does other work.

atmel_lcdfb: LCDC startup fix
This patch adds an additional loop, that delays turning off the DMA
until the LCDC core has been turned off. This prevents the picture
to be shifted some random length when the kernel re-initializes
the LCDC.
Without this patch, the LCDC keeps running for some small time after the
PWRCON:LCD_PWR has been cleared ; the FIFO suffers an underrun and on
re-starting the LCDC the FIFO data stays shifted.
This behavior has been seen and fixed on AT91SAM9261-EK and two custom
AT91SAM9261 boards, all of them having different LCD panels.

fb_ddc: fix DDC lines quirk
The code in fb_ddc_read() is said to be based on the implementation of the
radeon driver:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=fc5891c8a3ba284f13994d7bc1f1bfa8283982de
However, comparing the old radeon driver code with the new fb_ddc code
reveals some differences. Most notably, the I2C bus lines are held at the
end of the function, while the original code was releasing them (as the
comment above correctly says.)
There are a few other differences, which appear to be responsible for read
failures on my system. While tracing low-level I2C code in i2c-algo-bit, I
noticed that the initial attempt to read the EDID always failed. It takes
one retry for the read to succeed. As we are about to remove this
automatic retry property from i2c-algo-bit, reading the EDID would really
fail.
As a summary, the I2C lines quirk which is supposedly needed to read EDID
on some older monitors is currently breaking the (first) read on all other
monitors (and might not even work with older ones - did anyone try since
October 2006?)
After applying the patch below, which makes the code in fb_ddc_read()
really similar to what the radeon driver used to have, the first EDID read
succeeds again.
On top of that, as it appears that this code has been broken for one year
now and nobody seems to have complained, I'm curious if it makes sense to
keep this quirk in place. It makes the code more complex and slower just
for the sake of monitors which I guess nobody uses anymore. Can't we just
get rid of it?

could keeping this revoke from hell.
b) In a situation when module is gone but PDE still alive, standard

Fix boot problem with iSeries lacking hugepage support
Ordinarily the size of a pageblock is determined at compile-time based on the
hugepage size. On PPC64, the hugepage size is determined at runtime based on
what is supported by the machine. With legacy machines such as iSeries that
do not support hugepages, HPAGE_SHIFT is 0. This results in pageblock_order
being set to -PAGE_SHIFT and a crash results shortly afterwards.
This patch adds a function to select a sensible value for pageblock order by
default when HUGETLB_PAGE_SIZE_VARIABLE is set. It checks that HPAGE_SHIFT
is a sensible value before using the hugepage size; if it is not MAX_ORDER-1
is used.
This is a fix for 2.6.24.
