2013-07-05[SCSI] megaraid_sas: fix memory leak if SGL has zero length entriesBjørn Mork
commit 98cb7e44 ([SCSI] megaraid_sas: Sanity check user supplied length before passing it to dma_alloc_coherent()) introduced a memory leak. Memory allocated for entries following zero length SGL entries will not be freed.

The patch adds a check to the function esdhc_writeb in file sdhci-of-esdhc.c, where it checks if the write is done to the SDHCI_HOST_CONTROL register and th host has the above mentioned QUIRK, then the function simply returns instead of writing to the register.

This patch adds support of connecting an MMC media using an 8-bit bus width connection to Freescale's P2020 H/W SDHC controller. During the probe function, the generic function mmc_of_parse is called to detect whether the controller is configured with 8-bit bus width. Also, the generic function detects if the non-removable property is set in the device tree. The function esdhc_pltfm_bus_width was added because the bus width configuration is platform specific.

The field containing the production date in the CID register only uses 4 bits to encode the year, starting from 1997 in the original standard. In 2013, the production year field contains 0, and the kernel reports a 1997 production date. The eMMC 4.51 specification adds a new interpretation rule. For all devices implementing the 4.41 specification or later, the production year field will be interpreted as a value between 2010 and 2025, with 0 corresponding to 2013.

2013-07-05hrtimers: Move SMP function call to thread contextThomas Gleixner
smp_call_function_* must not be called from softirq context. But clock_was_set() which calls on_each_cpu() is called from softirq context to implement a delayed clock_was_set() for the timer interrupt handler. Though that almost never gets invoked. A recent change in the resume code uses the softirq based delayed clock_was_set to support Xens resume mechanism. linux-next contains a new warning which warns if smp_call_function_* is called from softirq context which gets triggered by that Xen change. Fix this by moving the delayed clock_was_set() call to a work context.

2013-07-05clocksource: Reselect clocksource when watchdog validated high-res capabilityThomas Gleixner
Up to commit 5d33b883a (clocksource: Always verify highres capability) we had no sanity check when selecting a clocksource, which prevented that a non highres capable clocksource is used when the system already switched to highres/nohz mode. The new sanity check works as Alex and Tim found out. It prevents the TSC from being used. This happens because on x86 the boot process looks like this: tsc_start_freqency_validation(TSC); clocksource_register(HPET); clocksource_done_booting(); clocksource_select() Selects HPET which is valid for high-res switch_to_highres(); clocksource_register(TSC); TSC is not selected, because it is not yet flagged as VALID_HIGH_RES clocksource_watchdog() Validates TSC for highres, but that does not make TSC the current clocksource. Before the sanity check was added, we installed TSC unvalidated which worked most of the time. If the TSC was really detected as unstable, then the unstable logic removed it and installed HPET again. The sanity check is correct and needed. So the watchdog needs to kick a reselection of the clocksource, when it qualifies TSC as a valid high res clocksource. To solve this, we mark the clocksource which got the flag CLOCK_SOURCE_VALID_FOR_HRES set by the watchdog with an new flag CLOCK_SOURCE_RESELECT and trigger the watchdog thread. The watchdog thread evaluates the flag and invokes clocksource_select() when set. To avoid that the clocksource_done_booting() code, which is about to install the first real clocksource anyway, needs to go through clocksource_select and tick_oneshot_notify() pointlessly, split out the clocksource_watchdog_kthread() list walk code and invoke the select/notify only when called from clocksource_watchdog_kthread(). So clocksource_done_booting() can utilize the same splitout code without the select/notify invocation and the clocksource_mutex unlock/relock dance.

2013-07-05sfc: Fix memory leak when discarding scattered packetsBen Hutchings
Commit 2768935a4660 ('sfc: reuse pages to avoid DMA mapping/unmapping costs') did not fully take account of DMA scattering which was introduced immediately before. If a received packet is invalid and must be discarded, we only drop a reference to the first buffer's page, but we need to drop a reference for each buffer the packet used. I think this bug was missed partly because efx_recycle_rx_buffers() was not renamed and so no longer does what its name says. It does not change the state of buffers, but only prepares the underlying pages for recycling. Rename it accordingly. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S.

2013-07-05dmaengine/trivial: at_hdmac: add curly brackets to if/else expressionsNicolas Ferre
Correct coding style following the patch: 7c407d3e54dcc0c79119553c8d5ef176c1d5bc3a (DMA: AT91: Get residual bytes in dma buffer). Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com>
2013-07-05dmaengine: at_hdmac: remove unsuded atc_cleanup_descriptors()Nicolas Ferre
Since patch 7c407d3e54dcc0c79119553c8d5ef176c1d5bc3a (DMA: AT91: Get residual bytes in dma buffer), the function atc_cleanup_descriptors() is not used anymore. We remove it to prevent warnings.

2013-07-05dmaengine: at_hdmac: add FIFO configuration parameter to DMA DT bindingLudovic Desroches
For most devices the FIFO configuration is the same i.e. when half FIFO size is available/filled, a source/destination request is serviced. But USART devices have to do it when there is enough space/data available to perform a single AHB access so the ASAP configuration.

2013-07-05ARM: at91: dt: add header to define at_hdmac configurationLudovic Desroches
DMA-cell content is a concatenation of several values. In order to keep this stuff human readable, macros are introduced. The values for the FIFO configuration are not the same as the ones used in the configuration register in order to keep backward compatibility. Most devices use the half FIFO configuration but USART ones have to use the ASAP configuration. This parameter was not initially planed to be into the at91 dma dt binding. The third cell will be used to store this parameter, it will become a concatenation of the FIFO configuration and of the peripheral ID. In order to keep backward compatibility i.e. FIFO configuration is equal to 0, we have to perform a translation since the value to put in the register to set half FIFO is 1.
