2016-10-14irqchip/gicv3: Handle loop timeout properDan Carpenter
The timeout loop terminates when the loop count is zero, but the decrement of the count variable is post check. So count is -1 when we check for the timeout and therefor the error message is supressed. Change it to predecrement, so the error message is emitted.

2016-10-14irqchip/jcore: Fix lost per-cpu interruptsRich Felker
The J-Core AIC does not have separate interrupt numbers reserved for cpu-local vs global interrupts. Instead, the driver requesting the irq is expected to know whether its device uses per-cpu interrupts or not. Previously it was assumed that handle_simple_irq could work for both cases, but it intentionally drops interrupts for an irq number that already has a handler running. This resulted in the timer interrupt for one cpu being lost when multiple cpus' timers were set for approximately the same expiration time, leading to stalls. In theory the same could also happen with IPIs. To solve the problem, instead of registering handle_simple_irq as the handler, register a wrapper function which checks whether the irq to be handled was requested as per-cpu or not, and passes it to handle_simple_irq or handle_percpu_irq accordingly.

2016-10-13net: phy: Trigger state machine on state change and not polling.Andrew Lunn
The phy_start() is used to indicate the PHY is now ready to do its work. The state is changed, normally to PHY_UP which means that both the MAC and the PHY are ready. If the phy driver is using polling, when the next poll happens, the state machine notices the PHY is now in PHY_UP, and kicks off auto-negotiation, if needed. If however, the PHY is using interrupts, there is no polling. The phy is stuck in PHY_UP until the next interrupt comes along. And there is no reason for the PHY to interrupt. Have phy_start() schedule the state machine to run, which both speeds up the polling use case, and makes the interrupt use case actually work. This problems exists whenever there is a state change which will not cause an interrupt. Trigger the state machine in these cases, e.g. phy_error().

If a VIF has been ready for rx_stall_timeout (60s by default) and an Rx ring is drained of all requests an Rx stall will be incorrectly detected. When this occurs and the guest Rx queue is empty, the Rx ring's event index will not be set and the frontend will not raise an event when new requests are placed on the ring, permanently stalling the VIF. This is a regression introduced by eb1723a29b9a7 (xen-netback: refactor guest rx). Fix this by reinstating the setting of queue->last_rx_time when placing a packet onto the guest Rx ring.

The Quectel EC21 and EC25 need the same "set DTR" request as devices based on the MDM9230 chipset, but has no USB3 support. Our best guess is that the "set DTR" functionality depends on chipset and/or baseband firmware generation. But USB3 is still an optional feature. Since we cannot enable this unconditionally for all older devices, and there doesn't appear to be anything we can use in the USB descriptors to identify these chips, we are forced to use a device specific quirk flag.

It is useful to be able to see the hash configuration when running tests. This patch adds a debugfs node for that purpose. The original version of this patch (commit c0c64c152389) was reverted due to build failures caused by a conflict with commit 0364a8824c02 ("xen-netback: switch to threaded irq for control ring"). This new version of the patch is nearly identical to the original, the only difference being that creation of the debugfs node is predicated on 'ctrl_irq' being non-zero rather then the now non-existent 'ctrl_task'.

2016-10-13cpufreq: conservative: Fix next frequency selectionRafael J. Wysocki
Commit d352cf47d93e (cpufreq: conservative: Do not use transition notifications) overlooked the case when the "frequency step" used by the conservative governor is small relative to the distances between the available frequencies and broke the algorithm by using policy->cur instead of the previously requested frequency when computing the next one. As a result, the governor may not be able to go outside of a narrow range between two consecutive available frequencies. Fix the problem by making the governor save the previously requested frequency and select the next one relative that value (unless it is out of range, in which case policy->cur will be used instead).

2016-10-13mmc: sdhci-esdhc-imx: Correct two register accessesAaron Brice
- The DMA error interrupt bit is in a different position as compared to the sdhci standard. This is accounted for in many cases, but not handled in the case of clearing the INT_STATUS register by writing a 1 to that location. - The HOST_CONTROL register is very different as compared to the sdhci standard. This is accounted for in the write case, but not when read back out (which it is in the sdhci code).

2016-10-12platform/x86: asus-wmi: add SERIO_I8042 dependencyArnd Bergmann
A recent bugfix added a call to i8042_install_filter but did not add the dependency, leading to possible link errors: drivers/platform/built-in.o: In function `asus_nb_wmi_quirks': asus-nb-wmi.c:(.text+0x23af): undefined reference to `i8042_install_filter' This adds a dependency on SERIO_I8042||SERIO_I8042=n to indicate that we can build the driver when the i8042 driver is disabled, but it cannot be built-in when that is a loadable module.

2016-10-12acpi_os_vprintf: Use printk_get_level() to avoid unnecessary KERN_CONTJoe Perches
acpi_os_vprintf currently always uses a KERN_CONT prefix which may be followed immediately by a proper KERN_<LEVEL>. Check if the buffer already has a KERN_<LEVEL> at the start of the buffer and avoid the unnecessary KERN_CONT. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Rafael J.

2016-10-12drm/amdgpu: clarify UVD/VCE special handling for CGAlex Deucher
UVD and VCE CG are handled specially, however the previous fix for this skipped late init for those blocks rather than just CG. Just protect the CG function call. No functional change since UVD and VCE don't currently utilize a late_init function. Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2016-10-12drm/amd/amdgpu: enable clockgating only after late initArindam Nath
Sometimes during multiple reboots, the system hangs during bootup. The issue is very random and happens once in around 50 reboots or so. It seems if clockgating is enabled before late init, the GFX engine sometimes does not respond. This patch changes the ordering a little so that both powergating and clockgating are enabled only after late init calls.
