2016-02-25ARM: dts: sun8i-h3: Add R_PIO controller node to the dtsiKrzysztof Adamski
Add the corresponding device node for R_PIO on H3 to the dtsi. Support for the controller was added in earlier commit. Signed-off-by: Krzysztof Adamski <k@japko.eu> Acked-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
2016-02-25dts: sun8i-h3: Add APB0 related clocks and resetsKrzysztof Adamski
APB0 is bearly mentioned in H3 User Manual and it is only setup in the Allwinners kernel dump for CIR. I have verified experimentally that the gate for R_PIO exists and works, though. There are probably other gates there but I don't know their order right now and I don't have access to their peripherals on my board to test them. After some experiments and reviewing how this is organized on other sunxi SoCs, I couldn't actually find any way to disable clocks for R_PIO and they are working properly without doing anything so I assume they are connected straight to the 24Mhz oscillator for now.

2016-02-25ARM: dts: sun7i: Add dts file for the lamobo-r1 boardJelle de Jong
The lamobo-r1 board, sometimes called the BPI-R1 but not labelled as such on the PCB, is meant as a A20 based router board. As such the board comes with a built-in switch chip giving it 5 gigabit ethernet ports, and it has a large empty area on the pcb with mounting holes which will fit a 2.5 inch harddisk. To complete its networking features it has a Realtek RTL8192CU for WiFi 802.11 b/g/n.

2016-01-24vmstat: Remove BUG_ON from vmstat_updateChristoph Lameter
If we detect that there is nothing to do just set the flag and do not check if it was already set before. Races really do not matter. If the flag is set by any code then the shepherd will start dealing with the situation and reenable the vmstat workers when necessary again. Since commit 0eb77e988032 ("vmstat: make vmstat_updater deferrable again and shut down on idle") quiet_vmstat might update cpu_stat_off and mark a particular cpu to be handled by vmstat_shepherd. This might trigger a VM_BUG_ON in vmstat_update because the work item might have been sleeping during the idle period and see the cpu_stat_off updated after the wake up. The VM_BUG_ON is therefore misleading and no more appropriate. Moreover it doesn't really suite any protection from real bugs because vmstat_shepherd will simply reschedule the vmstat_work anytime it sees a particular cpu set or vmstat_update would do the same from the worker context directly. Even when the two would race the result wouldn't be incorrect as the counters update is fully idempotent.

2016-01-24MIPS: bcm963xx: Move extended flash address to bcm_tag header fileSimon Arlott
The extended flash address needs to be subtracted from bcm_tag flash image offsets. Move this value to the bcm_tag header file. Renamed define name to consistently use bcm963xx for flash layout which should be considered a property of the board and not the SoC (i.e. bcm63xx could theoretically be used on a board without CFE or any flash).
