John W. Linville says:

====================
Here is another batch of updates intended for 3.7...

Highlights include an hci_connect re-write in Bluetooth, HCI/LLC
layer separation in NFC, removal of the raw pn544 NFC driver, NFC LLCP
raw sockets support, improved IBSS auth frame handling in mac80211,
full-MAC AP mode notification support in mac80211, a lot of attention
paid to brcmfmac, and the usual level of updates to iwlwifi, ath9k,
mwifiex, and rt2x00, and various other updates.
====================

----------------------------
What: Removing the pn544 raw driver.
When: 3.6
Why: With the introduction of the NFC HCI and SHDL kernel layers, pn544.c
is being replaced by pn544_hci.c which is accessible through the netlink
and socket NFC APIs. Moreover, pn544.c is outdated and does not seem to
work properly with the latest Android stacks.
Having 2 drivers for the same hardware is confusing and as such we
should only keep the one following the kernel NFC APIs.
Who: Samuel Ortiz <sameo@linux.intel.com>
----------------------------
What: setitimer accepts user NULL pointer (value)
When: 3.6
Why: setitimer is not returning -EFAULT if user pointer is NULL. This
