2012-11-20vtime: Warn if irqs aren't disabled on system time accounting APIsFrederic Weisbecker
System time accounting APIs such as vtime_account_system() and vtime_account_idle() need to be irqsafe. Current callers include irq entry, exit and kvm, all of which have been checked against that requirement. Now it's better to grow that with an automatic check in case we have further callers or we missed something.

Commit 8214513 ("ARM: EXYNOS: fix address for EXYNOS4 MDMA1") changed EXYNOS specific setup of PL330 DMA engine to use 'non-secure' mdma1 address instead of 'secure' one (from 0x12840000 to 0x12850000) to fix issue with some Exynos4212 SOCs. Unfortunately it brakes PL330 setup for revision 0 of Exynos4210 SOC (mdma1 device cannot be found at 'non-secure' address): [ 0.566245] dma-pl330 dma-pl330.2: PERIPH_ID 0x0, PCELL_ID 0x0 !

2012-11-19of/net/mdio-gpio: Fix pdev->id issue when using devicetrees.Srinivas Kandagatla
When the mdio-gpio driver is probed via device trees, the platform device id is set as -1, However the pdev->id is re-used as bus-id for while creating mdio gpio bus. So For device tree case the mdio-gpio bus name appears as "gpio-ffffffff" where as for non-device tree case the bus name appears as "gpio-<bus-num>" Which means the bus_id is fixed in device tree case, so we can't have two mdio gpio buses via device trees. Assigning a logical bus number via device tree solves the problem and the bus name is much consistent with non-device tree bus name. Without this patch 1. we can't support two mdio-gpio buses via device trees. 2. we should always pass gpio-ffffffff as bus name to phy_connect, very different to non-device tree bus name. So, setting up the bus_id via aliases from device tree is the right solution and other drivers do similar thing.

2012-11-19staging:iio:adis: Preallocate transfer messageLars-Peter Clausen
Currently the driver reads out all sample registers of the device and throws away those which it does not need. Furthermore the SPI message is constructed each time the trigger handler is run, although it will be the same each time. This patch preallocates and pre-constructs the SPI message in the "update_scan_mode" callback. Only those register which are actually selected for sampling are included in the message. The patch also gets rid of the conversion of the sample data from big endian to the native endianness and instead marks the channel as big endian in its scan type. This allows to directly push the SPI transfer buffer to the IIO buffer without the need to post-process it.
