When booting with pci=nomsi aer causes lost interrupts and
lockdep inversions.
So check if MSIs are not disabled before initializing the aer
driver.

The definition of the ASPM support field in the Link Capabilities
Register had been changed by the "ASPM optionality ECN" as follows:
<Before>
00b Reserved
01b L0s Supported
10b Reserved
11b L0s and L1 Supported
<After>
00b No ASPM Support
01b L0s Supported
10b L1 Supported
11b L0s and L1 Supported
Current linux ASPM driver doesn't enable ASPM if the support field is
00b or 10b. So there is no impact about 00b. But current linux ASPM
driver doesn't enable L1 if the support field is 10b. With this patch,
10b (L1 support) is handled properly.

Devtmpfs lets the kernel create a tmpfs instance called devtmpfs
very early at kernel initialization, before any driver-core device
is registered. Every device with a major/minor will provide a
device node in devtmpfs.
Devtmpfs can be changed and altered by userspace at any time,
and in any way needed - just like today's udev-mounted tmpfs.
Unmodified udev versions will run just fine on top of it, and will
recognize an already existing kernel-created device node and use it.
The default node permissions are root:root 0600. Proper permissions
and user/group ownership, meaningful symlinks, all other policy still
needs to be applied by userspace.
If a node is created by devtmps, devtmpfs will remove the device node
when the device goes away. If the device node was created by
userspace, or the devtmpfs created node was replaced by userspace, it
will no longer be removed by devtmpfs.
If it is requested to auto-mount it, it makes init=/bin/sh work
without any further userspace support. /dev will be fully populated
and dynamic, and always reflect the current device state of the kernel.
With the commonly used dynamic device numbers, it solves the problem
where static devices nodes may point to the wrong devices.
It is intended to make the initial bootup logic simpler and more robust,
by de-coupling the creation of the inital environment, to reliably run
userspace processes, from a complex userspace bootstrap logic to provide
a working /dev.

When turning class devices into bus devices, we may need to
temporarily add links in sysfs so that user-space applications
are not confused. This is done by adding the following API:
* Functions to register and unregister compatibility classes.
These appear in sysfs at the same location as regular classes, but
instead of class devices, they contain links to bus devices.
* Functions to create and delete such links. Additionally, the caller
can optionally pass a target device to which a "device" link should
point (typically that would be the device's parent), to fully emulate
the original class device.
The i2c subsystem will be the first user of this API, as i2c adapters
are being converted from class devices to bus devices.

This adds a generic uio driver that can bind to any PCI device. First
user will be virtualization where a qemu userspace process needs to give
guest OS access to the device.
Interrupts are handled using the Interrupt Disable bit in the PCI
command register and Interrupt Status bit in the PCI status register.
All devices compliant to PCI 2.3 (circa 2002) and all compliant PCI
Express devices should support these bits. Driver detects this support,
and won't bind to devices which do not support the Interrupt Disable Bit
in the command register.
It's expected that more features of interest to virtualization will be
added to this driver in the future. Possibilities are: mmap for device
resources, MSI/MSI-X, eventfd (to interface with kvm), iommu.

When I build and boot -next on fedora 10, I can not login anymore.
When I input the user name and password, the system does not output
any message and requires user to input the user name and password
again and again.
I find the patch which caused this problem with "GIT BISECT" command.
And the patch is
commit 7c4b7daa1878972ed0137c95f23569124bd6e2b1
"mem_class: use minor as index instead of searching the array".
Though I don't know the real reason why user could not login, I
confirmed the patch I made as following could resolve the problem on
fedora 10.

No one should directly access the driver_data field, so remove the field
and make it private. We dynamically create the private field now if it
is needed, to handle drivers that call get/set before they are
registered with the driver core.
Also update the copyright notices on these files while we are there.

This patch (as1271) affects when new devices get linked into their
bus's list of devices. Currently this happens after probing, and it
doesn't happen at all if probing fails. Clearly this is wrong,
because at that point quite a few symbolic links have already been
created in sysfs. We are committed to adding the device, so it should
be linked into the bus's list regardless.
In addition, this needs to happen before the uevent announcing the new
device gets issued. Otherwise user programs might try to access the
device before it has been added to the bus.
To fix both these problems, the patch moves the call to
klist_add_tail() forward from bus_attach_device() to bus_add_device().
Since bus_attach_device() now does nothing but probe for drivers, it
has been renamed to bus_probe_device(). And lastly, the kerneldoc is
updated.

Both drivers (rt2860 and rt3090) register themselves as "rt2860" on
loading the module.
In the very rare case of somebody having two cards in his machine, one
using rt3090 and the other one using the rt2860 driver, loading both
modules would be impossible, the second one will not be loaded as the
kernel will tell you that the driver is already registered.
This was also present with rt2870/rt3070 (with both driver registering
as "rt2870"), but the code has been merged to one driver recently.
The follwoing patch fixes this potential problem until merging of
rt2860/rt3090 code to a single driver.

When compiling rt2860/rt2870/rt3070 or rt3090 on x86_64, the following warning
is displayed:
drivers/staging/rt3090/rt_linux.c: In function 'duplicate_pkt':
drivers/staging/rt3090/rt_linux.c:531: warning: passing argument 1 of 'memmove' makes pointer from integer without a cast
include2/asm/string_64.h:58: note: expected 'void *' but argument is of type 'sk_buff_data_t'

The result of container_of should not be NULL. In particular, in this case
the argument to the enclosing function has passed though INIT_WORK, which
dereferences it, implying that its container cannot be NULL.
A simplified version of the semantic patch that makes this change is as
follows:
(http://www.emn.fr/x-info/coccinelle/)
// <smpl>
@@
identifier fn,work,x,fld;
type T;
expression E1,E2;
statement S;
@@
static fn(struct work_struct *work) {
... when != work = E1
x = container_of(work,T,fld)
... when != x = E2
- if (x == NULL) S
...
}
// </smpl>

So it doesn't conflict with a mainline kernel driver
currently under development.

Now that the code is in the kernel tree, remove the unneeded version
checks.

There has been some block api changes since the last
release of the cowloop code. This patch updates the code to
properly build.

Cowloop is a "copy-on-write" pseudo block driver. It can
be stacked on top of a "real" block driver, and catches
all write operations on their way from the file systems
layer above to the real driver below, effectively shielding
the lower driver from those write accesses. The requests are
then diverted to an ordinary file, located somewhere else
(configurable). Later read requests are checked to see whether
they can be serviced by the "real" block driver below, or
must be pulled in from the diverted location. More information
is on the project's website http://www.ATComputing.nl/cowloop/

We need to actually wait a specific ammount of time, not just hope that
a set number of loops will be long enough.
Based on a conversation with Ralink, and a proposed patch for their
older kernel driver.
