+Subject: [PATCH] ath9k: Fix RTC_DERIVED_CLK usage
+
+Based on the reference clock, which could be 25MHz or 40MHz,
+AR_RTC_DERIVED_CLK is programmed differently for AR9340 and AR9550.
+But, when a chip reset is done, processing the initvals
+sets the register back to the default value.
+
+Fix this by moving the code in ath9k_hw_init_pll() to
+ar9003_hw_override_ini(). Also, do this override for AR9531.

+b43_phy_copy() accesses phy_read and phy_write directly and will fail

+
+The commit that went into 3.17:
+
+ ath9k: Summarize hw state per channel context
+
+ Group and set hw state (opmode, primary_sta, beacon conf) per
+ channel context instead of whole list of vifs. This would allow
+ each channel context to run in different mode (STA/AP).

+
+broke multi-vif configuration due to not properly calculating
+the bssid mask.
+
+The test case that caught this was:
+
+ create wlan0 and sta0-4 (6 total), not sure how much that matters.
+ associate all 6 (works fine)
+ disconnect 5 of them, leaving sta0 up
+ Start trying to bring up the other 5 one at a time. It will
+ fail, with iw events looking like this (in these logs, several
+ sta are trying to come up, but symptom is the same with just one)
+
+The patch causing the regression made quite a few changes, but
+the part I think caused this particular problem was not
+recalculating the bssid mask when adding and removing interfaces.
+
+Re-adding those calls fixes my test case. Fix bad comment
+as well.

+Subject: [PATCH] rt2x00: do not align payload on modern H/W
+
+RT2800 and newer hardware require padding between header and payload if
+header length is not multiple of 4.
+
+For historical reasons we also align payload to to 4 bytes boundary, but
+such alignment is not needed on modern H/W.

+Patch improve performance on embedded CPUs and _possibly_ fixes
+skb_under_panic problems reported from time to time:

-[RFC] rt2x00: For drivers that only need L2 padding don't realign frames
-
-Signed-off-by: Helmut Schaa <helmut.schaa@...>
----
-
-Ivo, Gertjan, do you remeber by any chance why this alignment stuff was added
-in the first place? Was it because of DMA restrictions?
-
-While doing some profiling on the rt3052 SoC I noticed that 30-40% time was
-spent in memmove calls. And the culprit is the memmove aligning the payload
-to a 4byte boundary since that has to move a whole bunch of data.
-
-Interesstingly the legacy drivers insert an l2pad between the header and the
-payload but doesn't realign the payload itself to a 4-byte boundary. Hence,
-I came up with this patch and indeed CPU usage improves impressively.
-
-Only tested on rt2800pci!
-
-Thanks,
-Helmut
