2012-12-20ARM: OMAP2+: Trivial fix for IOMMU merge issueTony Lindgren
Commit 787314c35fbb ("Merge tag 'iommu-updates-v3.8' of git://git./linux/kernel/git/joro/iommu") did not account for the changed header location. The headers were made local to mach-omap2 as they are specific to omap2+ only, and we wanted to get most of the #include <plat/*.h> headers fixed up anyways for the ARM multiplatform support. We attempted to avoid this kind of merge conflict early on by setting up a minimal git branch shared by the arm-soc tree and the iommu tree, but looks like we still hit a merge issue there as the branches got merged as various topic branches.

git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu Pull IOMMU updates from Joerg Roedel: "A few new features this merge-window. The most important one is probably, that dma-debug now warns if a dma-handle is not checked with dma_mapping_error by the device driver. This requires minor changes to some architectures which make use of dma-debug. Most of these changes have the respective Acks by the Arch-Maintainers. Besides that there are updates to the AMD IOMMU driver for refactor the IOMMU-Groups support and to make sure it does not trigger a hardware erratum. The OMAP changes (for which I pulled in a branch from Tony Lindgren's tree) have a conflict in linux-next with the arm-soc tree. The conflict is in the file arch/arm/mach-omap2/clock44xx_data.c which is deleted in the arm-soc tree. It is safe to delete the file too so solve the conflict. Similar changes are done in the arm-soc tree in the common clock framework migration.

2012-12-20UAPI: Fix up empty files in arch/cris/David Howells
Fix up three empty files in arch/cris/ by sticking placeholder comments in there to prevent the patch program from deleting them. I decided not to delete the arch-v*/Kbuild files as it's possibly someone might want to use them for genhdr-y lines in the future, but they could be deleted and the pointer lines removed from asm/Kbuild. The uapi/arch-v*/Kbuild files ought to be uneffected by such a change. asm/swab.h didn't have anything outside of __KERNEL__ so nothing appeared in uapi/asm/swab.h. The latter, however, is exported by Kbuild.asm. This needs to be applied after the CRIS UAPI disintegration patch.

2012-12-19sparc64: Fix unrolled AES 256-bit key loops.David S. Miller
The basic scheme of the block mode assembler is that we start by enabling the FPU, loading the key into the floating point registers, then iterate calling the encrypt/decrypt routine for each block. For the 256-bit key cases, we run short on registers in the unrolled loops. So the {ENCRYPT,DECRYPT}_256_2() macros reload the key registers that get clobbered. The unrolled macros, {ENCRYPT,DECRYPT}_256(), are not mindful of this. So if we have a mix of multi-block and single-block calls, the single-block unrolled 256-bit encrypt/decrypt can run with some of the key registers clobbered. Handle this by always explicitly loading those registers before using the non-unrolled 256-bit macro. This was discovered thanks to all of the new test cases added by Jussi Kivilinna.

2012-12-19new helper: compat_user_stack_pointer()Al Viro
Compat counterpart of current_user_stack_pointer(); for most of the biarch architectures those two are identical, but e.g. arm64 and arm use different registers for stack pointer... Note that amd64 variants of current_user_stack_pointer/compat_user_stack_pointer do *not* rely on pt_regs having been through FIXUP_TOP_OF_STACK. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2012-12-19new helper: current_user_stack_pointer()Al Viro
Cross-architecture equivalent of rdusp(); default is user_stack_pointer(current_pt_regs()) - that works for almost all platforms that have usp saved in pt_regs. The only exception from that is ia64 - we want memory stack, not the backing store for register one. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2012-12-19Bury the conditionals from kernel_thread/kernel_execve seriesAl Viro
All architectures have CONFIG_GENERIC_KERNEL_THREAD CONFIG_GENERIC_KERNEL_EXECVE __ARCH_WANT_SYS_EXECVE None of them have __ARCH_WANT_KERNEL_EXECVE and there are only two callers of kernel_execve() (which is a trivial wrapper for do_execve() now) left. Kill the conditionals and make both callers use do_execve(). Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2012-12-19ARM: EXYNOS: Avoid passing the clks through platform dataPadmavathi Venna
I2S controller has an internal mux for RCLK source clks. The list of source clk names were passed through platform data in non-dt case. The variable holding the list of RCLK source clk names is not required, as the list of clks need to be registered with clkdev using generic connection id. This is required as part of adding DT support for I2S controller driver.
