2012-11-30s390/pci: PCI adapter interrupts for MSI/MSI-XJan Glauber
Support PCI adapter interrupts using the Single-IRQ-mode. Single-IRQ-mode disables an adapter IRQ automatically after delivering it until the SIC instruction enables it again. This is used to reduce the number of IRQs for streaming workloads. Up to 64 MSI handlers can be registered per PCI function. A hash table is used to map interrupt numbers to MSI descriptors. The interrupt vector is scanned using the flogr instruction. Only MSI/MSI-X interrupts are supported, no legacy INTs.

2012-11-30ARM: OMAP: Move plat-omap/dma-omap.h to include/linux/omap-dma.hTony Lindgren
Based on earlier discussions[1] we attempted to find a suitable location for the omap DMA header in commit 2b6c4e73 (ARM: OMAP: DMA: Move plat/dma.h to plat-omap/dma-omap.h) until the conversion to dmaengine is complete. Unfortunately that was before I was able to try to test compile of the ARM multiplatform builds for omap2+, and the end result was not very good. So I'm creating yet another all over the place patch to cut the last dependency for building omap2+ for ARM multiplatform. After this, we have finally removed the driver dependencies to the arch/arm code, except for few drivers that are being worked on. The other option was to make the <plat-omap/dma-omap.h> path to work, but we'd have to add some new header directory to for multiplatform builds. Or we would have to manually include arch/arm/plat-omap/include again from arch/arm/Makefile for omap2+. Neither of these alternatives sound appealing as they will likely lead addition of various other headers exposed to the drivers, which we want to avoid for the multiplatform kernels. Since we already have a minimal include/linux/omap-dma.h, let's just use that instead and add a note to it to not use the custom omap DMA functions any longer where possible. Note that converting omap DMA to dmaengine depends on dmaengine supporting automatically incrementing the FIFO address at the device end, and converting all the remaining legacy drivers. So it's going to be few more merge windows.

2012-11-30ring-buffer: Fix race between integrity check and readersSteven Rostedt
The function rb_check_pages() was added to make sure the ring buffer's pages were sane. This check is done when the ring buffer size is modified as well as when the iterator is released (closing the "trace" file), as that was considered a non fast path and a good place to do a sanity check. The problem is that the check does not have any locks around it. If one process were to read the trace file, and another were to read the raw binary file, the check could happen while the reader is reading the file. The issues with this is that the check requires to clear the HEAD page before doing the full check and it restores it afterward. But readers require the HEAD page to exist before it can read the buffer, otherwise it gives a nasty warning and disables the buffer. By adding the reader lock around the check, this keeps the race from happening. Cc: stable@vger.kernel.org # 3.6 Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2012-11-30ring-buffer: Fix NULL pointer if rb_set_head_page() failsSteven Rostedt
The function rb_set_head_page() searches the list of ring buffer pages for a the page that has the HEAD page flag set. If it does not find it, it will do a WARN_ON(), disable the ring buffer and return NULL, as this should never happen. But if this bug happens to happen, not all callers of this function can handle a NULL pointer being returned from it. That needs to be fixed.

If everything goes right, it shouldn't really matter if we are spitting this warning after css_alloc or css_online. If we fail between then, there are some ill cases where we would previously see the message and now we won't (like if the files fail to be created).

2012-11-30iio:imu: adis16480: show_firmware() buffer too smallDan Carpenter
Smatch complains that snprintf() returns the number of characters, not counting the NUL terminator, which *would* have been printed if there were enough space. In other words the return value could be more than sizeof(buf). In this case, we are printing something like "ff.ff\n" which is at most 6 characters and a NUL so that's not an issue. I changed snprintf() to scnprintf() to silence the warning. But since the buffer doesn't include space for the NUL terminator, we need to make it bigger or the "\n" will be truncated off.
