Subject: [PATCH 1/6] staging: hv: Enable sending GARP packet after live
migration
The hv_netvsc gets RNDIS_STATUS_MEDIA_CONNECT event after the VM
is live migrated. Adding call to netif_notify_peers() for this event
to send GARP (Gratuitous ARP) to notify network peers. Otherwise,
the VM's network connection may stop after a live migration.
This patch should also be applied to stable kernel 2.6.32 and later.

Subject: [PATCH 3/6] staging: brcm80211: bugfix for softmac crash on multi cpu
configurations
Solved a locking issue that resulted in driver crashes with the 43224 and 43225
chips. The problem has been reported on several fora. Root cause was two fold:
hardware was being manipulated by two unsynchronized threads, and a scan
operation could interfere with an ongoing dynamic calibration process. Fix was
to invoke a lock on wl_ops_config() operation and to set internal flags when a
scan operation is started and stopped.
Please add this to the staging-linus branch.

As mentioned by W. Trevor King on the devel@linuxdriverproject.org list
on "Thu, 27 Jan 2011 18:52:15 -0500", "Message-ID:
<20110127235214.GA5107@thialfi.dhcp.drexel.edu>", the ni_pcimio module
is missing module metadata, including a license.
This patch adds module metadata to all the NI comedi driver modules. It
also removes a duplicate MODULE_LICENSE("GPL") line from the "mite"
module.
