2013-04-29net: mac802154: comparision issue of type cast, finding by EXTRA_CFLAGS=-WChen Gang
Change MAC802154_CHAN_NONE from ~(u8)0 to 0xff, or the comparison in mac802154_wpan_xmit() for ``chan == MAC802154_CHAN_NONE'' will not succeed. This bug can be boiled down to ``u8 foo = 0xff; if (foo == ~(u8)0) [...] else [...]'' where the condition will always take the else branch.

2013-04-29selftests: psock_tpacket: fix status checkDaniel Borkmann
Testing like this for TP_STATUS_AVAILABLE clearly is a stupid bug since it always returns true. Fix this by only checking for flags where the kernel owns the packet and negate this result, since we also could run into the non-zero status TP_STATUS_WRONG_FORMAT and need to reclaim frames.

2013-04-29NFSv4: Servers should only check SETATTR stateid open mode on size changeTrond Myklebust
The NFSv4 and NFSv4.1 specs are both clear that the server should only check stateid open mode if a SETATTR specifies the size attribute. If the open mode is not one that allows writing, then it returns NFS4ERR_OPENMODE. In the case where the SETATTR is not changing the size, the client will still pass it the delegation stateid to ensure that the server does not recall that delegation. In that case, the server should _ignore_ the delegation open mode, and simply apply standard permission checks. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2013-04-29Turn off -Wmaybe-uninitialized when building with -OsArnd Bergmann
gcc-4.7 and higher add a lot of false positive warnings about potential uses of uninitialized warnings, but only when optimizing for size (-Os). This is the default when building allyesconfig, which turns on CONFIG_CC_OPTIMIZE_FOR_SIZE. In order to avoid getting a lot of patches that initialize such variables and accidentally hide real errors along the way, let's just turn off this warning on the respective gcc versions when building with size optimizations. The -Wmaybe-uninitialized option was introduced in the same gcc version (4.7) that is now causing the false positives, so there is no effect on older compilers. A side effect is that when building with CONFIG_CC_OPTIMIZE_FOR_SIZE, we might now see /fewer/ warnings about possibly uninitialized warnings than with -O2, but that is still much better than seeing warnings known to be bogus.

2013-04-29irqchip: s3c24xx: add missing __init annotationsArnd Bergmann
The s3c24xx_init_intc and s3c2412_init_irq functions are only called at init time, and they call functions already marked __init, so they should be marked in the same way.

2013-04-29edac: sb_edac.c should not require prescence of IMC_DDRIO deviceLuck, Tony
The Sandy Bridge EDAC driver uses a register in the IMC_DDRIO CSR space to determine the type of DIMMs (registered or unregistered). But this device does not exist on some single socket Sandy Bridge servers. While the type of DIMMs is nice to know, it is not essential for this driver's other functions. So it seems harsh to have it refuse to load at all when it cannot find this device. Make the check for this device be optional. If it isn't present just report the memory type as "MEM_UNKNOWN".

2013-04-29ALSA: USB: adjust for changed 3.8 USB APIClemens Ladisch
The recent changes in the USB API ("implement new semantics for URB_ISO_ASAP") made the former meaning of the URB_ISO_ASAP flag the default, and changed this flag to mean that URBs can be delayed. This is not the behaviour wanted by any of the audio drivers because it leads to discontinuous playback with very small period sizes. Therefore, our URBs need to be submitted without this flag.

2013-04-29drm/exynos: add device tree support for fimc ipp driverSylwester Nawrocki
This patch adds OF initialization support for the FIMC driver. The binding documentation can be found at Documentation/devicetree/ bindings/media/samsung-fimc.txt. The syscon regmap interface is used to serialize access to the shared CAMBLK registers from within the V4L2 FIMC-IS and the DRM FIMC drivers. The DRM driver uses this interface for setting up the FIFO data link between FIMD and FIMC IP blocks, while the V4L2 one for setting up a data link between the camera ISP and FIMC for camera capture. The CAMBLK registers are not accessed any more through a statically mapped IO. Synchronized access to these registers is required for simultaneous operation of the camera ISP and the DRM IPP on Exynos4x12. The driver data and driver_ids static data structures are removed since Exynos4 is going to be a dt-only platform and there is currently no board file in mainline that defines platform data for the FIMC IPP, i.e. uses it. Camera input signal polarities are not currently parsed from the device tree.

2013-04-29drm/exynos: rework fimc clocks handlingSylwester Nawrocki
The clocks handling is refactored and a "mux" clock handling is added to account for changes in the clocks driver. After switching to the common clock framework the sclk_fimc clock is now split into two clocks: a gate and a mux clock. In order to retain the exisiting functionality two additional consumer clocks are passed to the driver from device tree: "mux" and "parent". Then the driver sets "parent" clock as a parent clock of the "mux" clock. These two additional clocks are optional, and should go away when there is a standard way of setting up parent clocks on DT platforms.
