* nfs41: serialize first layoutget of a filePeng Tao2015-02-032-4/+32
| | | | | | | | | | | | | | | | | Per RFC 5661 Errata 3208: | A client MAY always forget its layout state and associated | layout stateid at any time (See also section 12.5.5.1). | In such case, the client MUST use a non-layout stateid for the next | LAYOUTGET operation. This will signal the server that the client has | no more layouts on the file and its respective layout state can be | released before issuing a new layout in response to LAYOUTGET. In order to make such a signal unique to server, client needs to serialize all layoutgets using non-layout stateid. We implement this by serializing layoutgets when client has no layout segments at hand. Signed-off-by: Peng Tao <tao.peng@primarydata.com> Signed-off-by: Tom Haynes <Thomas.Haynes@primarydata.com>

Set the .control_parent flag to delegate masking to the parent interrupt controller, like was already done for irqpin1. Without this, accessing the three-axis digital accelerometer ADXL345 on kzm9g through /dev/input/event1 causes an interrupt storm, which requires a power-cycle to recover from.

Reason: The PIOE2 pin is connected to the NAND_Tree# of KSZ8081, But it outputs LOW during the reset period, which cause the NAND_Tree# enabled. Add phy_fixup() to disable NAND_Tree by overriding the Operation Mode Strap Override register(i.e. Register 16h) to clear the NAND_Tree bit.

| * | | ARM: rockchip: disable jtag/sdmmc autoswitching on rk3288Heiko Stübner2015-01-161-0/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | rk3288 SoCs have a function to automatically switch between jtag/sdmmc pinmux settings depending on the card state. This collides with a lot of assumptions. It only works when using the internal card-detect mechanism and breaks horribly when using either the normal card-detect via the slot-gpio function or via any other pin. Also there is of course no link between the mmc and jtag on the software-side, so the jtag clocks may very well be disabled when the card is ejected and the soc switches back to the jtag pinmux. Leaving the switching function enabled did result in mmc timeouts and rcu stalls thus hanging the system on 3.19-rc1. Therefore disable it in all cases, as we expect the devicetree to explicitly select either mmc or jtag pinmuxes anyway.
