The debug level can be set by passing debug=... to brcmsmac whenever
CONFIG_BRCMDBG is enabled.

1ca47e687a brcm80211: Convert log message levels to debug levels
In preparation for enhancements to debug and trace support, convert the
message levels to debug levels which will be used for enabling
categories of debug messages. The two message levels are little-used
anyway and are combined into the BRCM_DL_INFO debug level.

f5c4f10852 brcm80211: Allow trace support to be enabled separately from debug
Since the runtime overhead of trace support is small when tracing is
disabled, users may be interested in turning on trace support while
leaving other debug features off. Add a new config option named
CONFIG_BRCM_TRACING for this purpose.

75be3e24ee brcmsmac: Reduce number of entries in tx DMA rings
Currently up to 256 frames can be queued for each DMA ring. This is
excessive, and now that we have better flow control we can get by with
less. Experimentation has shown 64 to work well.

b05618deb4 brcmsmac: Use correct descriptor count when calculating next rx descriptor
nextrxd() is calling txd(), which means that the tx descriptor count is
used to determine when to wrap for determining the next ring buffer
entry. This has worked so far since the driver has been using the same
number of rx and tx descriptors, but it's obviously going to be a
problem if different numbers of descriptors are used.

e041f65d5f brcmsmac: Remove internal tx queue
The brcmsmac internal tx buffering is problematic. The amount of
buffering is excessive (228 packets in addition to the 256 slots in each
DMA ring), and frames may be dropped due to a lack of flow control.

This patch reworks the transmit code path to remove the internal
buffering. Frames are immediately handed off to the DMA support rather
than passing through an intermediate queue. Non-aggregate frames are
queued immediately into the tx rings, and aggregate frames are queued
temporarily in an AMPDU session until ready for transmit.

Transmit flow control is also added to avoid dropping packets when the
tx rings are full. Conceptually this is a separate change, but it's
included in this commit because removing the tx queue without adding
flow control could cause significant problems.

32d0f12a16 brcmsmac: Use IEEE 802.11 AC levels for pktq precedence levels
The mac80211 tx queues and brcmsmac DMA fifos both map directly to AC
levels. Therefore it's much more straightforward to queue tx frames and
choose the tx fifo based on the mac80211 queue instead of mapping 802.1D
priority tags to precedence levels then back to AC levels. mac80211
already maps the 802.1D levels to the appropriate AC levels and queues
management frames at the maximum priority, so the results should be
identical.

One functional change resulting from this patch is that AMPDU retries no
longer get a priority boost to queue them ahead of packets with the same
priority already in the tx queue. This behavior will be restored (in
effect at least) in a later patch when the tx queue is removed.

5c8067caee brcmsmac: Don't weight AMPDU packets in txfifo
According to the comments this "reduces rate lag," but in reality the
only way this value is used is for determining whether or not any frames
remain to be transmitted. Therefore there's no reason for AMPDU packets
to receive any weighting.

ef2c0512bb brcmsmac: Introduce AMPDU sessions for assembling AMPDUs
AMPDU session allows MPDUs to be temporarily queued until either a full
AMPDU has been collected or circumstances dictate that transmission
should start with a partial AMPDU. Packets are added to the session by
calling brcms_c_ampdu_add_frame(). brcms_c_ampdu_finalize() should be
called to fix up the tx headers in the first and last packet before
adding the packets to the DMA ring. brmcs_c_sendampdu() is converted to
using AMPDU sessions.

This patch has no real value on it's own, but is needed in preparation
for elimination of the tx packet queue from brcmsmac.

Overlay Virtual Ethernet (DOVE) networks. The patch includes:

	+ a dove flag per VXLAN device to enable DOVE extensions
	+ ARP reduction, whereby a bridge-connected VXLAN tunnel endpoint
		answers ARP requests from the local bridge on behalf of
		remote DOVE clients
	+ route short-circuiting (aka L3 switching). Known destination IP
		addresses use the corresponding destination MAC address for
		switching rather than going to a (possibly remote) router first.
	+ netlink notification messages for forwarding table and L3 switching
		misses

Changes since v2
	- combined bools into "u32 flags"
	- replaced loop with !is_zero_ether_addr()

The Intel 82855PM host bridge / Mobility FireGL 9000 RV250 combination
in an (outdated) ThinkPad T41 needs AGPMode 1 for suspend/resume (under
KMS, that is). So add a quirk for it.

(Change R250 to RV250 in comment for preceding quirk too.)

cece5c4009 ARM: ux500: Describe UART platform registering issues more accurately
UARTs no longer require call-back information, since the reset
call-back was removed in 43b5f0d692.
The only AUXDATA dependencies remaining for UARTs are DMA settings.

e506d6fde5 drm/i915: disable cloning on sdvo
After the recent pile of disable-cloning patches, e.g.

commit e3b86d6941
Author: Egbert Eich <eich@suse.de>
Date:   Sat Oct 13 14:30:15 2012 +0200

    DRM/i915: Don't clone SDVO LVDS with analog

and a bug report from Chris Wilson indicating that cloning doesn't
even work for DVI-SDVO and native VGA, let's just disable cloning on
sdvo encoders completely.

v2: Update the comment in the code as discussed with Paulo Zanoni.

34c93c8657 dma: mv_xor: Add a device_control function
The dmatest module for DMA engines calls

device_control(dtc->chan, DMA_TERMINATE_ALL, 0);

after completing the tests. The documentation in
include/linux/dmaengine.h suggests this function is optional and
dma_async_device_register() also does not BUG_ON() when not passed a
function. However, dmatest is not the only code in the kernel
unconditionally calling device_control. So add an implementation
indicating all operations are not implemented.
