x86/PCI: use host bridge _CRS info on ASUS M2V-MX SE
In summary, this DMI quirk uses the _CRS info by default for the ASUS
M2V-MX SE by turning on `pci=use_crs` and is similar to the quirk
added by commit 2491762cfb47 ("x86/PCI: use host bridge _CRS info on
ASRock ALiveSATA2-GLAN") whose commit message should be read for further
information.
Since commit 3e3da00c01d0 ("x86/pci: AMD one chain system to use pci
read out res") Linux gives the following oops:
Trusting the ACPI _CRS information (`pci=use_crs`) fixes this problem.
$ dmesg | grep -i crs # with the quirk
PCI: Using host bridge windows from ACPI; if necessary, use "pci=nocrs" and report a bug
The match has to be against the DMI board entries though since the vendor entries are not populated.
DMI: System manufacturer System Product Name/M2V-MX SE, BIOS 0304 10/30/2007
This quirk should be removed when `pci=use_crs` is enabled for machines
from 2006 or earlier or some other solution is implemented.
Using coreboot [1] with this board the problem does not exist but this
quirk also does not affect it either. To be safe though the check is
tightened to only take effect when the BIOS from American Megatrends is
used.

virtio-net: Verify page list size before fitting into skb
This patch verifies that the length of a buffer stored in a linked list
of pages is small enough to fit into a skb.
If the size is larger than a max size of a skb, it means that we shouldn't
go ahead building skbs anyway since we won't be able to send the buffer as
the user requested.

This is based on an earlier patch by Nick Carter with comments
by David Lamparter but with some refinements. Thanks for their patience
this is a confusing area with overlap of standards, user requirements,
and compatibility with earlier releases.
It adds a new sysfs attribute
/sys/class/net/brX/bridge/group_fwd_mask
that controls forwarding of frames with address of: 01-80-C2-00-00-0X
The default setting has no forwarding to retain compatibility.
One change from earlier releases is that forwarding of group
addresses is not dependent on STP being enabled or disabled. This
choice was made based on interpretation of tie 802.1 standards.
I expect complaints will arise because of this, but better to follow
the standard than continue acting incorrectly by default.
The filtering mask is writeable, but only values that don't forward
known control frames are allowed. It intentionally blocks attempts
to filter control protocols. For example: writing a 8 allows
forwarding 802.1X PAE addresses which is the most common request.

This resolves a regression seen by some users of bridging.
Some users use the bridge like a dummy device.
They expect to be able to put an IPv6 address on the device
with no ports attached. Although there are better ways of doing
this, there is no reason to not allow it.
Note: the bridge still will reflect the state of ports in the
bridge if there are any added.

PM / Hibernate: Add resumewait param to support MMC-like devices as resume file
Some devices like MMC are async detected very slow. For example,
drivers/mmc/host/sdhci.c launches a 200ms delayed work to detect
MMC partitions then add disk.
We have wait_for_device_probe() and scsi_complete_async_scans()
before calling swsusp_check(), but it is not enough to wait for MMC.
This patch adds resumewait kernel param just like rootwait so
that we have enough time to wait until MMC is ready. The difference is
that we wait for resume partition whereas rootwait waits for rootfs
partition (which may be on a different device).
This patch will make hibernation support many embedded products
without SCSI devices, but with devices like MMC.
