2012-03-30Documentation: replace install commands with softdepsLucas De Marchi
Install commands should not be used to specify soft dependencies among modules. When loading modules it's much better to have a softdep that modprobe knows what's being done than having to fork/exec another instance of modprobe to load the other module. By using a softdep user has also an option to remove the dependencies when removing the module (and if its refcount dropped to 0) Signed-off-by: Lucas De Marchi <lucas.demarchi@profusion.mobi> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2012-03-30genirq: Adjust irq thread affinity on IRQ_SET_MASK_OK_NOCOPY return valueJiang Liu
irq_move_masked_irq() checks the return code of chip->irq_set_affinity() only for 0, but IRQ_SET_MASK_OK_NOCOPY is also a valid return code, which is there to avoid a redundant copy of the cpumask. But in case of IRQ_SET_MASK_OK_NOCOPY we not only avoid the redundant copy, we also fail to adjust the thread affinity of an eventually threaded interrupt handler. Handle IRQ_SET_MASK_OK (==0) and IRQ_SET_MASK_OK_NOCOPY(==1) return values correctly by checking the valid return values seperately.

2012-03-30ACPI throttling: fix endian bug in acpi_read_throttling_status()Dan Carpenter
Using a u64 here creates an endian bug. We store a u32 number in the top byte which is a larger number than intended on big endian systems. There is no reason to use a 64 bit data type here, I guess it was just an oversight. I removed the initialization to zero as well. It's needed with a u64 but with a u32, the variable gets initialized properly inside the call to acpi_os_read_port().

git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs Pull btrfs fixes and features from Chris Mason: "We've merged in the error handling patches from SuSE. These are already shipping in the sles kernel, and they give btrfs the ability to abort transactions and go readonly on errors. It involves a lot of churn as they clarify BUG_ONs, and remove the ones we now properly deal with. Josef reworked the way our metadata interacts with the page cache. page->private now points to the btrfs extent_buffer object, which makes everything faster. He changed it so we write an whole extent buffer at a time instead of allowing individual pages to go down,, which will be important for the raid5/6 code (for the 3.5 merge window ;) Josef also made us more aggressive about dropping pages for metadata blocks that were freed due to COW. Overall, our metadata caching is much faster now. We've integrated my patch for metadata bigger than the page size. This allows metadata blocks up to 64KB in size. In practice 16K and 32K seem to work best. For workloads with lots of metadata, this cuts down the size of the extent allocation tree dramatically and fragments much less. Scrub was updated to support the larger block sizes, which ended up being a fairly large change (thanks Stefan Behrens). We also have an assortment of fixes and updates, especially to the balancing code (Ilya Dryomov), the back ref walker (Jan Schmidt) and the defragging code (Liu Bo)."

For architectures which define arch_idle_time (currently s390 only) this is a change for the worse.

Commit 68b7f715 ("nommu: ptrace support") added definitions for PT_TEXT_ADDR and friends, as well as adding ptrace support for reading from these magic offsets. Unfortunately, this has probably never worked, since ptrace_read_user predicates reading on off < sizeof(struct user), returning -EIO otherwise.

The recent merge of the sa11x0 code into mainline had silent conflicts with further development of the DMA engine API, leading to build errors and warnings: drivers/net/irda/sa1100_ir.c: In function 'sa1100_irda_dma_start': drivers/net/irda/sa1100_ir.c:151: error: too few arguments to function 'chan->device->device_prep_slave_sg' drivers/dma/sa11x0-dma.c: In function 'sa11x0_dma_probe': drivers/dma/sa11x0-dma.c:950: warning: assignment from incompatible pointer type Fix these.

2012-03-30sh: vsyscall: Fix up .eh_frame generation.Paul Mundt
Some improper formatting caused the .eh_frame generation to fail, resulting in gcc/g++ testsuite failures with regards to unwinding through the vDSO. Now that someone is actually working on this on the gcc side it's time to fix up the kernel side, too. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2012-03-30sh: dwarf unwinder depends on SHcompact.Paul Mundt
Presently there's no SHmedia support plugged in for the dwarf unwinder. While it's trivial to provide an SHmedia version of dwarf_read_arch_reg(), the general sh64 case is more complicated in that the TLB miss handler uses a locked down set of registers for optimization (including the frame pointer) which we need for the unwind table generation. While freeing up the frame pointer for use in the TLB miss handler is reasonably straightforward, it's still more trouble than it's worth, so we simply restrict the unwinder to 32-bit for now.
