+Date: Mon, 14 Mar 2016 15:18:36 +0100
+Subject: ath9k: fix buffer overrun for ar9287
+
+Code that was added back in 2.6.38 has an obvious overflow
+when accessing a static array, and at the time it was added
+only a code comment was put in front of it as a reminder
+to have it reviewed properly.
+
+This has not happened, but gcc-6 now points to the specific
+overflow:
+
+drivers/net/wireless/ath/ath9k/eeprom.c: In function 'ath9k_hw_get_gain_boundaries_pdadcs':
+drivers/net/wireless/ath/ath9k/eeprom.c:483:44: error: array subscript is above array bounds [-Werror=array-bounds]
+     maxPwrT4[i] = data_9287[idxL].pwrPdg[i][4];
+                   ~~~~~~~~~~~~~~~~~~~~~~~~~^~~
+
+It turns out that the correct array length exists in the local
+'intercepts' variable of this function, so we can just use that
+instead of hardcoding '4', so this patch changes all three
+instances to use that variable. The other two instances were
+already correct, but it's more consistent this way.

-Note: If you are upgrading from one of the previous 4.2 xen builds, and are having issues
-      with graphics card passthrough, the default device model used has changed and the 
-      newer model can sometimes have issues. To work around these issue, support for the
-      old style qemu-xen-traditional device model has been enabled. To use, add (or change)
-      the following line into the configuration file for the domain you want to use 
-      passthrough with:
-         device_model_version = "qemu-xen-traditional"
-
-      Also remember to rebuild your grub configuration if upgrading from a non-xen 4.5.0
-      install.
-
-      The xend daemon and the xm toolset have now been removed with the xen 4.5 release.
-
-      This install is now using a new version of the 09_xen file, used when generating
-      a new grub.cfg file. The new version inherits the default linux-libre kernel command
-      line settings; to use the old method, uncomment the 'XEN_LINUX_CMDLINE_OVERRIDE'
-      option in /etc/xen/grub.conf and change the '0' to '1'
