2012-04-06mmc: sdhci-s3c: Remove usage of clk_type member in platform dataThomas Abraham1-4/+70
SDHCI controllers on Exynos4 do not include the sdclk divider as per the sdhci controller specification. This case can be represented using the sdhci quirk SDHCI_QUIRK_NONSTANDARD_CLOCK instead of using an additional enum type definition 'clk_types'. Hence, usage of clk_type member in platform data is removed and the sdhci quirk is used. In addition to that, since this qurik is SoC specific, driver data is introduced to represent controllers on SoC's that require this quirk.

2012-04-06bonding: properly unset current_arp_slave on slave link upVeaceslav Falico1-1/+5
When a slave comes up, we're unsetting the current_arp_slave without removing active flags from it, which can lead to situations where we have more than one slave with active flags in active-backup mode. To avoid this situation we must remove the active flags from a slave before removing it as a current_arp_slave.

2012-04-06simple_open: automatically convert to simple_open()Stephen Boyd47-463/+152
Many users of debugfs copy the implementation of default_open() when they want to support a custom read/write function op. This leads to a proliferation of the default_open() implementation across the entire tree. Now that the common implementation has been consolidated into libfs we can replace all the users of this function with simple_open(). This replacement was done with the following semantic patch: <smpl> @ open @ identifier open_f != simple_open; identifier i, f; @@ -int open_f(struct inode *i, struct file *f) -{ ( -if (i->i_private) -f->private_data = i->i_private; | -f->private_data = i->i_private; ) -return 0; -} @ has_open depends on open @ identifier fops; identifier open.open_f; @@ struct file_operations fops = { ... -.open = open_f, +.open = simple_open, ... }; </smpl> [akpm@linux-foundation.org: checkpatch fixes] Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Al Viro <viro@zeniv.linux.org.uk> Cc: Julia Lawall <Julia.Lawall@lip6.fr> Acked-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2012-04-06sysrq: use SEND_SIG_FORCED instead of force_sig()Anton Vorontsov1-1/+1
Change send_sig_all() to use do_send_sig_info(SEND_SIG_FORCED) instead of force_sig(SIGKILL). With the recent changes we do not need force_ to kill the CLONE_NEWPID tasks. And this is more correct. force_sig() can race with the exiting thread, while do_send_sig_info(group => true) kill the whole process. Some more notes from Oleg Nesterov: > Just one note. This change makes no difference for sysrq_handle_kill(). > But it obviously changes the behaviour sysrq_handle_term(). I think > this is fine, if you want to really kill the task which blocks/ignores > SIGTERM you can use sysrq_handle_kill(). > > Even ignoring the reasons why force_sig() is simply wrong here, > force_sig(SIGTERM) looks strange. The task won't be killed if it has > a handler, but SIG_IGN can't help. However if it has the handler > but blocks SIGTERM temporary (this is very common) it will be killed. Also, > force_sig() can't kill the process if the main thread has already > exited. IOW, it is trivial to create the process which can't be > killed by sysrq. So, this patch fixes the issue.

2012-04-05mlx4: allocate just enough pages instead of always 4 pagesThadeu Lima de Souza Cascardo1-2/+3
The driver uses a 2-order allocation, which is too much on architectures like ppc64, which has a 64KiB page. This particular allocation is used for large packet fragments that may have a size of 512, 1024, 4096 or fill the whole allocation. So, a minimum size of 16384 is good enough and will be the same size that is used in architectures of 4KiB sized pages. This will avoid allocation failures that we see when the system is under stress, but still has plenty of memory, like the one below. This will also allow us to set the interface MTU to higher values like 9000, which was not possible on ppc64 without this patch.

git://git.linaro.org/people/mszyprowski/linux-dma-mapping Pull DMA mapping branch from Marek Szyprowski: "Short summary for the whole series: A few limitations have been identified in the current dma-mapping design and its implementations for various architectures. There exist more than one function for allocating and freeing the buffers: currently these 3 are used dma_{alloc, free}_coherent, dma_{alloc,free}_writecombine, dma_{alloc,free}_noncoherent. For most of the systems these calls are almost equivalent and can be interchanged. For others, especially the truly non-coherent ones (like ARM), the difference can be easily noticed in overall driver performance. Sadly not all architectures provide implementations for all of them, so the drivers might need to be adapted and cannot be easily shared between different architectures. The provided patches unify all these functions and hide the differences under the already existing dma attributes concept. The thread with more references is available here: http://www.spinics.net/lists/linux-sh/msg09777.html These patches are also a prerequisite for unifying DMA-mapping implementation on ARM architecture with the common one provided by dma_map_ops structure and extending it with IOMMU support. More information is available in the following thread: http://thread.gmane.org/gmane.linux.kernel.cross-arch/12819 More works on dma-mapping framework are planned, especially in the area of buffer sharing and managing the shared mappings (together with the recently introduced dma_buf interface: commit d15bd7ee445d "dma-buf: Introduce dma buffer sharing mechanism"). The patches in the current set introduce a new alloc/free methods (with support for memory attributes) in dma_map_ops structure, which will later replace dma_alloc_coherent and dma_alloc_writecombine functions." People finally started piping up with support for merging this, so I'm merging it as the last of the pending stuff from the merge window. Looks like pohmelfs is going to wait for 3.5 and more external support for merging. * 'for-linus' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping: common: DMA-mapping: add NON-CONSISTENT attribute common: DMA-mapping: add WRITE_COMBINE attribute common: dma-mapping: introduce mmap method common: dma-mapping: remove old alloc_coherent and free_coherent methods Hexagon: adapt for dma_map_ops changes Unicore32: adapt for dma_map_ops changes Microblaze: adapt for dma_map_ops changes SH: adapt for dma_map_ops changes Alpha: adapt for dma_map_ops changes SPARC: adapt for dma_map_ops changes PowerPC: adapt for dma_map_ops changes MIPS: adapt for dma_map_ops changes X86 & IA64: adapt for dma_map_ops changes common: dma-mapping: introduce generic alloc() and free() methods

Modified from original patch from Chris. The sky2 driver has to have 8 byte alignment of receive buffer on some chip versions. On architectures which don't support efficient unaligned access this doesn't work very well. The solution is to just copy all received packets which is what the driver already does for small packets. This allows the driver to be used on the Tilera TILEmpower-Gx, since the tile architecture doesn't currently handle kernel unaligned accesses, just userspace.

The current implemenation was buggy for slaves who use ndo_neigh_setup, since the networking stack invokes the bonding device ndo entry (from neigh_params_alloc) before any devices are enslaved, and the bonding driver can't further delegate the call at that point in time. As a result when bonding IPoIB devices, the neigh_cleanup hasn't been called. Fix that by deferring the actual call into the slave ndo_neigh_setup from the time the bonding neigh_setup is called.

Change number of ports to 3 for newer SoCs. Modify pdata structure and ohci-at91 code that was dealing with ports information and check of port indexes.

2012-04-04USB: ohci-at91: rework and fix initializationNicolas Ferre1-42/+46
The DT information are filled in a pdata structure and then passed on to the usual check code of the probe function. Thus we do not need to redo the gpio checking and irq configuration in the DT-related code. On the other hand, we setup GPIO direction in driver for vbus and overcurrent. It will be useful when moving to pinctrl subsystem.

This reverts commit d06221c0617ab6d0bc41c4980cefdd9c8cc9a1c1. It turns out to trigger the "BUG_ON(!PageCompound(page))" in kfree(), apparently because the code ends up trying to free somethng that was never kmalloced in the first place. BenH points out that the patch was untested and wasn't meant to go into the upstream kernel that quickly in the first place.

This driver was recently moved from IIO (where it worked) to hwmon (where it doesn't.) This breakage occured because the hwmon version neglected to correctly initialize a reference to spi_dev in its drvdata. The result is a segfault every time the temperature is queried.
