2012-12-07mmc: sdhci: implement the .card_event() methodGuennadi Liakhovetski
Extracting a part of the SDHCI card tasklet into a .card_event() implementation allows SDHCI hosts to use generic card-detection services, e.g. the GPIO slot function.

2012-12-07mmc: extend the slot-gpio card-detection to use host's .card_event() methodGuennadi Liakhovetski
The slot-gpio API provides a generic card-detection handler. To support a wider range of hosts it has to call the host's card-event callback, if implemented. Also increase the debounce interval to 200ms to match the SDHCI driver.

2012-12-07bnx2x: Prevent link flaps when booting from SAN.Barak Witkowski
It is possible that the driver is configured to operate with a certain link configuration which differs from the link's configuration during boot from SAN - this would cause the driver to flap the link. Said flap may be missed by specific switches, causing dcbx convergence to be too long and boot sequence to fail. Convergence is longer because switch ignores new dcbx packets due to counters mismatch, as only host side reset the counters due to the link flap. This patch causes the driver to ignore user's initial configuration during boot from SAN, and continues with the existing link configuration.

Commit f1ce3062c538 (ipv4: Remove 'rt_dst' from 'struct rtable') removes the call to ipmr_get_route(), which will get multicast parameters of the route. I revert the part of the patch that remove this call. I think the goal was only to get rid of rt_dst field. The patch is only compiled-tested.

Commit b9a50f74905a ("ARM: 7450/1: dcache: select DCACHE_WORD_ACCESS for little-endian ARMv6+ CPUs") added support for word-at-time path comparisons, relying on the ability to perform unaligned loads with negligible performance impact in hardware. For nommu configurations without MPU support, this is unpredictable and so we should fall back to the byte-by-byte routines.

2012-12-07ARM: 7592/1: nommu: prevent generation of kernel unaligned memory accessesWill Deacon
Recent ARMv7 toolchains assume that unaligned memory accesses will not fault and will instead be handled by the processor. For the nommu case (without an MPU), memory will be treated as strongly-ordered and therefore unaligned accesses may fault regardless of the SCTLR.A setting. This patch passes -mno-unaligned-access to GCC when compiling for nommu targets, preventing the generation of unaligned memory access in the kernel.

Previously, the ASoC 'platform' (PCM/DMA) object was instantiated via a platform_device.

2012-12-07HID: hidp: fallback to input session properly if hid is blacklistedLamarque V. Souza
This patch against kernel 3.7.0-rc8 fixes a kernel oops when turning on the bluetooth mouse with id 0458:0058 [1]. The mouse in question supports both input and hid sessions, however it is blacklisted in drivers/hid/hid-core.c so the input session is one that should be used. Long ago (around kernel 3.0.0) some changes in the bluetooth subsystem made the kernel do not fallback to input session when hid session is not supported or blacklisted. This patch restore that behaviour by making the kernel try the input session if hid_add_device returns ENODEV. The patch exports hid_ignore() from hid-core.c so that it can be used in the bluetooth subsystem. [1] https://bugzilla.kernel.org/show_bug.cgi?id=39882 Signed-off-by: Lamarque V.
