Merge tag 'nfc-next-3.7-1' of git://git./linux/kernel/git/sameo/nfc-3.0
So says Samuel Ortiz <sameo@linux.intel.com>:
This is the first NFC pull request for the 3.7 merge window.
With this one we get:
- HCI and LLC layers separation. We now can support various LLC
protocols for HCI drivers, SHDLC being one of them. This will be needed as
we're planning to support raw HCI chipsets that do the SHDLC encapsulation
in firmware. So for now we have an SHDLC and a NOP LLC layers.
- pn533 command queueing implementation. This simplifies the pn533 locking
logic and fixes a kernel warning.
- NCI p2p initiator mode implementation.
- Replace custom workqueues with system ones, for HCI and LLCP.
- Raw pn544 driver removal, as scheduled on the features-removal.txt file.
- A few HCI, SHDLC and LLCP fixes.

cfg80211: Fix regulatory check for 60GHz band frequencies
The current regulatory code on cfg80211 performs a check to
see if a regulatory rule belongs to an IEEE band so that if
a Country IE is received and no rules are specified for a
band (which is allowed by IEEE) those bands are left intact.
The current band check assumes a rule is bound to a band
if the rule's start or end frequency is less than 2 GHz
apart from the center of frequency being inspected.
In order to support 60 GHz for 802.11ad we need to increase
this to account for the channel spacing of 2160 MHz whereby
a channel somewhere in the middle of a regulatory rule may
be more than 2 GHz apart from either the beginning or
end of the frequency rule.
Without a fix for this even though channels 1-3 are allowed world
wide on the rule (57240 - 63720 @ 2160), channel 2 at 60480 MHz
will end up getting disabled given that it is 3240 MHz from
both the frequency rule start and end frequency. Fix this by
using 2 GHz separation assumption for the 2.4 and 5 GHz bands
but for 60 GHz use a 10 GHz separation before assuming a rule
is not part of the band.
Since we have no 802.11ad drivers yet merged this change has
no impact to existing Linux upstream device drivers.

rfkill: prevent unnecessary event generation
Prevent unnecessary rfkill event generation when the state has
not actually changed. These events have to be delivered to
relevant userspace processes, causing these processes to wake
up and do something while they could as well have slept. This
obviously results in more CPU usage, longer time-to-sleep-again
and therefore higher power consumption.

mac80211: don't send delBA when removing stations
When a station is removed and we stop the aggregation
sessions, it's not useful to send delBA since this is
due to us or the station disassociating or dropping
the connection in some other way, so change that.

mac80211: don't send delBA before disassoc
When we disassociate, it's not really useful to
send delBA action frames since we're going to send
disassoc/deauth anyway, so change that.

The suspend/resume code depends on CONFIG_PM, so
