In a PCI environment, transactions aren't always required to reach
the root bus before being re-routed. Intermediate switches between
an endpoint and the root bus can redirect DMA back downstream before
things like IOMMUs have a chance to intervene. Legacy PCI is always
susceptible to this as it operates on a shared bus. PCIe added a
new capability to describe and control this behavior, Access Control
Services, or ACS.
The utility function pci_acs_enabled() allows us to test the ACS
capabilities of an individual devices against a set of flags while
pci_acs_path_enabled() tests a complete path from a given downstream
device up to the specified upstream device. We also include the
ability to add device specific tests as it's likely we'll see
devices that do not implement ACS, but want to indicate support
for various capabilities in this space.

This patch resolves potential issues when accessing PCI Express
Capability structures. The makeup of the capability varies
substantially between v1 and v2:
Version 1 of the PCI Express Capability (defined by PCI Express
1.0 and 1.1 base) neither requires the endpoint to implement the
entire PCIe capability structure nor specifies default values of
registers that are not implemented by the device.
Version 2 of the PCI Express Capability (defined by PCIe 1.1
Capability Structure Expansion ECN, PCIe 2.0, 2.1, and 3.0) added
additional registers to the structure and requires all registers
to be either implemented or hardwired to 0.
Due to the differences in the capability structures, code dealing with
capability features must be careful not to access the additional
registers introduced with v2 unless the device is specifically known to
be a v2 capable device. Otherwise, attempts to access non-existant
registers will occur. This is a subtle issue that is hard to track down
when it occurs (and it has - see commit 864d296cf9).
To try and help mitigate such occurrences, this patch introduces
pci_pcie_cap2() which is similar to pci_pcie_cap() but also checks
that the PCIe capability version is >= 2. pci_pcie_cap2() should be
used for qualifying PCIe capability features introduced after v1.

DMA transactions are tagged with the source ID of the device making
the request. Occasionally hardware screws this up and uses the
source ID of a different device (often the wrong function number of
a multifunction device). A specific Ricoh multifunction device is
a prime example of this problem and included in this patch.
Given a pci_dev, this function returns the pci_dev to use as the
source ID for DMA. When hardware works correctly, this returns
the input device. For the components of the Ricoh multifunction
device, it returns the pci_dev for function 0.
This will be used by IOMMU drivers for determining the boundaries
of IOMMU groups as multiple devices using the same source ID must
be contained within the same group. This can also be used by
existing streaming DMA paths for the same purpose.

Yuck. The VIDIOC_(TRY_)DECODER_CMD ioctls already had ioctl numbers 96 and 97,
and after merging the timings API I forgot to continue numbering from 98. So
now we have two ioctls with number 96 and two with 97.
With the new table-driver ioctl handling in v4l2-ioctl.c it is essential that
each ioctl has its own unique number, so let's fix this quickly for 3.5.

The EDAC subsystem uses the old struct sysdev approach,
creating all nodes using the raw sysfs API. This is bad,
as the API is deprecated.
As we'll be changing the EDAC API, let's first port the existing
code to struct device.
There's one drawback on this patch: driver-specific sysfs
nodes, used by mpc85xx_edac, amd64_edac and i7core_edac
won't be created anymore. While it would be possible to
also port the device-specific code, that would mix kobj with
struct device, with is not recommended. Also, it is easier and nicer
to move the code to the drivers, instead, as the core can get rid
of some complex logic that just emulates what the device_add()
and device_create_file() already does.
The next patches will convert the driver-specific code to use
the device-specific calls. Then, the remaining bits of the old
sysfs API will be removed.
NOTE: a per-MC bus is required, otherwise devices with more than
one memory controller will hit a bug like the one below:

This happens because the bus is not being properly initialized.
Instead of putting the memory sub-devices inside the memory controller,
it is putting everything under the same directory:

On a multi-memory controller system, the names "csrow%d" and "dimm%d"
should be under "mc%d", and not at the main hierarchy level.
So, we need to create a per-MC bus, in order to have its own namespace.

" This series has four patches, the major point of which is to eliminate
some slowdowns (including boot-time slowdowns) resulting from some
RCU_FAST_NO_HZ changes. The issue with the changes is that posting timers
from the idle loop has no effect if the CPU has entered dyntick-idle
mode because the CPU has already computed its wakeup time, and posting
a timer does not cause it to be recomputed. The short-term fix is for
RCU to precompute the timeout value so that the CPU's calculation is
correct. "

Instead of reading in the resource groups when gfs2 is checking
for free space to allocate from, gfs2 can store the necessary infromation
in the resource group's lvb. Also, instead of searching for unlinked
inodes in every resource group that's checked for free space, gfs2 can
store the number of unlinked but inodes in the lvb, and only check for
unlinked inodes if it will find some.
The first time a resource group is locked, the lvb must initialized.
Since this involves counting the unlinked inodes in the resource group,
this takes a little extra time. But after that, if the resource group
is locked with GL_SKIP, the buffer head won't be read in unless it's
actually needed.
Enabling the resource groups lvbs is done via the rgrplvb mount option. If
this option isn't set, the lvbs will still be set and updated, but they won't
be verfied or used by the filesystem. To safely turn on this option, all of
the nodes mounting the filesystem must be running code with this patch, and
the filesystem must have been completely unmounted since they were updated.
