++/* ATI VBIOS Working Mechanism 
++ *
++ * Generally there are three memory resources (two MMIO and one PIO) 
++ * associated with modern ATI gfx. VBIOS uses special tricks to figure out 
++ * BARs, instead of using regular PCI config space read.
++ *
++ *  (1) VBIOS relies on I/O port 0x3C3 to retrieve PIO BAR 
++ *  (2) VBIOS maintains a shadow copy of PCI configure space. It retries the 
++ *      MMIO BARs from this shadow copy via sending I/O requests to first two 
++ *      registers of PIO (MMINDEX and MMDATA). The workflow is like this: 
++ *      MMINDEX (register 0) is written with an index value, specifying the 
++ *      register VBIOS wanting to access. Then the shadowed data can be 
++ *      read/written from MMDATA (register 1). For two MMIO BARs, the index 
++ *      values are 0x4010 and 0x4014 respectively.

+From: Arnd Bergmann <arnd@arndb.de>
+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.

+1. If using GRUB2, edit your GRUB2 config files as specified at
+    https://wiki.parabola.nu/index.php/Xen#Bootloader_Configuration
+
+    Support for the grub-mkconfig command was added, and will auto-discover
+     the deployed xen hypervisor and linux kernel
+2. If booting via efi, copy the example /etc/xen/efi-xen.cfg to /boot/xen.cfg
+   and edit the contents to match the settings you need.
+3. Issue the following commands to allow you to create and start VMs:
+
+    systemctl enable xen-qemu-dom0-disk-backend.service
+    systemctl enable xen-init-dom0.service
+    systemctl enable xenconsoled.service
+
+   Other optional services are:
+    systemctl enable xen-watchdog.service
+
+4. If you want some domains to automatically start up/shutdown, run the following:
+    systemctl enable xendomains.service
