2015-10-01blk-mq: fix racy updates of rq->errorsChristoph Hellwig6-27/+25
blk_mq_complete_request may be a no-op if the request has already been completed by others means (e.g. a timeout or cancellation), but currently drivers have to set rq->errors before calling blk_mq_complete_request, which might leave us with the wrong error value. Add an error parameter to blk_mq_complete_request so that we can defer setting rq->errors until we known we won the race to complete the request.

2015-10-01dmaengine: pxa_dma: fix residue corner caseRobert Jarzmik1-0/+10
A very tiny temporal window exists in the residue calculation where : - upon entering residue calculation, the transfer is ongoing - when reading the current transfer pointer, it just changed to the "finisher/linker" descriptor In this case, the residue returned is the whole transfer length instead of 0. Fix it. This appears almost in one extreme case, where the driver is used by older clients which inquire for residue in interrupt context, such as the smsc91x ethernet driver, in a tight loop : interrupt_handler() dmaengine_submit() do { dmaengine_tx_status() } while (residue > 0 || status != DMA_ERROR) Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Vinod Koul <vinod.koul@intel.com>

In this case, the card detect netsted interrupt is called from a threaded interrupt.

In recent allwinner kernel sources the mmc clk-delay settings have been slightly tweaked, and for sun9i they are completely different then what we are using. This commit brings us in sync with what allwinner does, fixing problems accessing sdcards on some A33 devices (and likely others). For pre sun9i hardware this makes the following changes: -At 400Khz change the sample delay from 7 to 0 (introduced in A31 sdk) -At 50 Mhz change the sample delay from 5 to 4 (introduced in A23 sdk) This also drops the clk-delay calculation for clocks > 50 MHz, we do not need this as we've: mmc->f_max = 50000000, and the delays in the old code were not correct (at 100 MHz the delay must be a multiple of 60, at 200 MHz a multiple of 120).

The size of the MAC register dump used to be the size specified by the reg property in the device tree. Userland has no good way of finding out that size, and it was not specified consistently for each MAC type, so ethtool would end up printing junk at the end of the register dump if the device tree didn't match the size it assumed.

2015-09-28watchdog: bcm2835: Fix poweroff behaviourNoralf Trønnes1-2/+8
Currently poweroff/halt results in a reboot on the Raspberry Pi. The firmware uses the RSTS register to know which partiton to boot from. The partiton value is spread into bits 0, 2, 4, 6, 8, 10. Partiton 63 is a special partition used by the firmware to indicate halt. The firmware made this change in 19 Aug 2013 and was matched by the downstream commit: Changes for new NOOBS multi partition booting from gsh Signed-off-by: Noralf Trønnes <noralf@tronnes.org> Tested-by: Stephen Warren <swarren@wwwdotorg.org> Acked-by: Stephen Warren <swarren@wwwdotorg.org> Reviewed-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>

2015-09-27irqchip: mips-gic: Fix pending & mask reads for MIPS64 with 32b GIC.Paul Burton1-0/+8
gic_handle_shared_int reads the GIC interrupt pending & mask registers directly into a bitmap, which is defined as an array of unsigned longs. The GIC pending registers may be 32 bits wide if the CM is older than CM3, regardless of the bit width of the CPU, but for MIPS64 kernels the unsigned longs in the bitmap will be 64 bits wide. In this case we need to perform 2 x 32 bit reads per 64 bit unsigned long in order to avoid missing interrupts.

Make use of the mips_cm_vp_id function to convert from Linux CPU numbers to the VP IDs used by hardware, which are not identical in all systems.
