2014-03-30spi: Fix handling of cs_change in core implementationMark Brown
The core implementation of cs_change didn't follow the documentation which says that cs_change in the middle of the transfer means to briefly deassert chip select, instead it followed buggy drivers which change the polarity of chip select. Use a delay of 10us between deassert and reassert simply from pulling numbers out of a hat. Reported-by: Gerhard Sittig <gsi@denx.de> Signed-off-by: Mark Brown <broonie@linaro.org>

2014-03-24vxlan: fix nonfunctional neigh_reduce()David Stevens
The VXLAN neigh_reduce() code is completely non-functional since check-in. Specific errors: 1) The original code drops all packets with a multicast destination address, even though neighbor solicitations are sent to the solicited-node address, a multicast address. The code after this check was never run. 2) The neighbor table lookup used the IPv6 header destination, which is the solicited node address, rather than the target address from the neighbor solicitation. So neighbor lookups would always fail if it got this far. Also for L3MISSes. 3) The code calls ndisc_send_na(), which does a send on the tunnel device. The context for neigh_reduce() is the transmit path, vxlan_xmit(), where the host or a bridge-attached neighbor is trying to transmit a neighbor solicitation. To respond to it, the tunnel endpoint needs to do a *receive* of the appropriate neighbor advertisement. Doing a send, would only try to send the advertisement, encapsulated, to the remote destinations in the fdb -- hosts that definitely did not do the corresponding solicitation. 4) The code uses the tunnel endpoint IPv6 forwarding flag to determine the isrouter flag in the advertisement. This has nothing to do with whether or not the target is a router, and generally won't be set since the tunnel endpoint is bridging, not routing, traffic. The patch below creates a proxy neighbor advertisement to respond to neighbor solicitions as intended, providing proper IPv6 support for neighbor reduction.

2014-03-24net: davinci_emac: Fix rollback of emac_dev_open()Christian Riesch
If an error occurs during the initialization in emac_dev_open() (the driver's ndo_open function), interrupts, DMA descriptors etc. must be freed. The current rollback code is buggy in several ways. 1) Freeing the interrupts. The current code will not free all interrupts that were requested by the driver. Furthermore, the code tries to do a platform_get_resource(priv->pdev, IORESOURCE_IRQ, -1) in its last iteration. This patch fixes these bugs. 2) Wrong order of err: and rollback: labels. If the setup of the PHY in the code fails, the interrupts that have been requested before are not freed: request irq if requesting irqs fails, goto rollback setup phy if phy setup fails, goto err return 0 rollback: free irqs err: This patch brings the code into the correct order. 3) The code calls napi_enable() and emac_int_enable(), but does not undo both in case of an error. This patch adds calls of emac_int_disable() and napi_disable() to the rollback code. 4) RX DMA descriptors are not freed in case of an error: Right before requesting the irqs, the function creates DMA descriptors for the RX channel. These RX descriptors are never freed when we jump to either rollback or err. This patch adds code for freeing the DMA descriptors in the case of an initialization error. This required a modification of cpdma_ctrl_stop() in davinci_cpdma.c: We must be able to call this function to free the DMA descriptors while the DMA channels are in IDLE state (before cpdma_ctlr_start() was called). Tested on a custom board with the Texas Instruments AM1808. Signed-off-by: Christian Riesch <christian.riesch@omicron.at> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-03-24net: davinci_emac: Replace devm_request_irq with request_irqChristian Riesch
In commit 6892b41d9701283085b655c6086fb57a5d63fa47 Author: Lad, Prabhakar <prabhakar.csengg@gmail.com> Date: Tue Jun 25 21:24:51 2013 +0530 net: davinci: emac: Convert to devm_* api the call of request_irq is replaced by devm_request_irq and the call of free_irq is removed. But since interrupts are requested in emac_dev_open, doing ifconfig up/down on the board requests the interrupts again each time, causing devm_request_irq to fail. The interface is dead until the device is rebooted. This patch reverts said commit partially: It changes the driver back to use request_irq instead of devm_request_irq, puts free_irq back in place, but keeps the remaining changes of the original patch.

2014-03-18net: cpsw: do not register cpts twiceBenedikt Spranger
commit f280e89a (drivers: net: cpsw: fix for cpsw crash when build as modules) moved cpts_register()/cpts_unregister() to ndo_open()/ndo_stop(), but failed to remove cpts_register in cpsw_probe() which leads to a double registration and the following debug object splat. [ 18.991902] ODEBUG: init active (active state 0) object type: timer_list hint: delayed_work_timer_fn+0x0/0x2c [ 19.082249] [<c0059e80>] (init_timer_key) from [<c04965d4>] (cpts_register+0x1f0/0x2c4) [ 19.090642] [<c04965d4>] (cpts_register) from [<c04931dc>] (cpsw_ndo_open+0x780/0x81c) [ 19.098948] [<c04931dc>] (cpsw_ndo_open) from [<c0599c2c>] (__dev_open+0xb4/0x118) Signed-off-by: Benedikt Spranger <b.spranger@linutronix.de> Signed-off-by: David S.

Pull final final block IO fixes from Jens Axboe: "Yes, the last round was final. This one is final final. The mtip32xx fix could have waited, but it's so simple and gets rid of two warning spewages on load. The two block flush fixes are critical for blk-mq, and are the primary reason for this late pull request" * 'for-linus' of git://git.kernel.dk/linux-block: mtip32xx: fix bad use of smp_processor_id() block: change flush sequence list addition back to front add block: fix q->flush_rq NULL pointer crash on dm-mpath flush
2014-03-17ATHEROS-ALX: Use dma_set_mask_and_coherent and fix a bugPeter Senna Tschudin
1. For the 64 bits dma mask use dma_set_mask_and_coherent instead of dma_set_mask and dma_set_coherent_mask. 2. For the 32 bits dma mask dma_set_coherent_mask is only called if dma_set_mask fails, which is unusual. Assuming this as a bug, fixes it by replacing calls to dma_set_mask and dma_set_coherent_mask by a call to dma_set_mask_and_coherent.
