2015-09-10xen-netback: respect user provided max_queuesWei Liu
Originally that parameter was always reset to num_online_cpus during module initialisation, which renders it useless. The fix is to only set max_queues to num_online_cpus when user has not provided a value.

2015-09-10drm/i915: Don't try to use DDR DVFS on CHV when disabled in the BIOSVille Syrjälä
If one disables DDR DVFS in the BIOS, Punit will apparently ignores all DDR DVFS request. Currently we assume that DDR DVFS is always operational, which leads to errors in dmesg when the DDR DVFS requests time out. Fix the problem by gently prodding Punit during driver load to find out whether it will respond to DDR DVFS requests. If the request times out, we assume that DDR DVFS has been permanenly disabled in the BIOS and no longer perster the Punit about it.

There exist one issue by below case that case system hang: ifconfig eth0 down ifconfig eth0 hw ether 00:10:19:19:81:19 After eth0 down, all fec clocks are gated off. In the .fec_set_mac_address() function, it will set new MAC address to registers, which causes system hang. So it needs to add netif status check to avoid registers access when clocks are gated off. Until eth0 up the new MAC address are wrote into related registers. V2: As Lucas Stach's suggestion, add a comment in the code to explain why it needed.

2015-09-09watchdog: add a driver to support SAMA5D4 watchdog timerWenyou Yang
From SAMA5D4, the watchdog timer is upgrated with a new feature, which is describled as in the datasheet, "WDT_MR can be written until a LOCKMR command is issued in WDT_CR". That is to say, as long as the bootstrap and u-boot don't issue a LOCKMR command, WDT_MR can be written more than once in the driver. So the SAMA5D4 watchdog driver's implementation is different from the at91sam9260 watchdog driver implemented in file at91sam9_wdt.c. The user application open the device file to enable the watchdog timer hardware, and close to disable it, and set the watchdog timer timeout by seting WDV and WDD fields of WDT_MR register, and ping the watchdog by issuing WDRSTT command to WDT_CR register with hard-coded key.

2015-09-09watchdog: gpio-wdt: ping already at startup for always running devicesUwe Kleine-König
During probe for an always-running watchdog a timer is setup to constantly ping the watchdog while the device is not open. The gpio to ping the watchdog is setup to inactive. For a watchdog with hw_algo = "toggle" this results in a ping depending on the initial state of the gpio, for hw_algo = "level" no ping is generated. Make sure that the first automatic ping is sent immediately and not only when the timer expires the first time. This makes the machine survive in case more than half of the watchdog timeout is already elapsed. (Which is very probable for the chip I'm faced with that has a timeout of one second.)

Commit f48da8b14d04ca87ffcffe68829afd45f926ec6a (xen-netback: fix unlimited guest Rx internal queue and carrier flapping) introduced a regression. The PV frontend in IPXE only places 4 requests on the guest Rx ring. Since netback required at least (MAX_SKB_FRAGS + 1) slots, IPXE could not receive any packets. a) If GSO is not enabled on the VIF, fewer guest Rx slots are required for the largest possible packet. Calculate the required slots based on the maximum GSO size or the MTU. This calculation of the number of required slots relies on 1650d5455bd2 (xen-netback: always fully coalesce guest Rx packets) which present in 4.0-rc1 and later. b) Reduce the Rx stall detection to checking for at least one available Rx request. This is fine since we're predominately concerned with detecting interfaces which are down and thus have zero available Rx requests.
