I've started to put the pull request wording into the merge commits, which are: - NoMMU stuff: This includes the following series sent earlier to the list: - nommu-fixes - R7 Support - MPU support I've left out the ARCH_MULTIPLATFORM/!MMU stuff that Arnd and I were discussing today until we've reached a conclusion/that's had some more review. This is rebased (and re-tested) on your devel-stable branch because otherwise there were going to be conflicts with Uwe's V7M work now that you've merged that. I've included the fix for limiting MPU to CPU_V7. - Huge page support These changes bring both HugeTLB support and Transparent HugePage (THP) support to ARM. Only long descriptors (LPAE) are supported in this series. The code has been tested on an Arndale board (Exynos 5250). - LPAE updates Please pull these miscellaneous LPAE fixes I've been collecting for a while now for 3.11. They've been tested and reviewed by quite a few people, and most of the patches are pretty trivial. -- Will Deacon. - arch_timer cleanups Please pull these arch_timer cleanups I've been holding onto for a while. They're the same as my last posting, but have been rebased to v3.10-rc3. - mpidr linearisation (multiprocessor id register - identifies which CPU number we are in the system) This patch series that implements MPIDR linearization through a simple hashing algorithm and updates current cpu_{suspend}/{resume} code to use the newly created hash structures to retrieve context pointers. It represents a stepping stone for the implementation of power management code on forthcoming multi-cluster ARM systems. It has been tested on TC2 (dual cluster A15xA7 system), iMX6q, OMAP4 and Tegra, with processors hitting low-power states requiring warm-boot resume through the cpu_resume code path" * 'for-linus' of git://git.linaro.org/people/rmk/linux-arm: (77 commits) ARM: 7775/1: mm: Remove do_sect_fault from LPAE code ARM: 7777/1: Avoid extra calls to the C compiler ARM: 7774/1: Fix dtb dependency to use order-only prerequisites ARM: 7770/1: remove residual ARMv2 support from decompressor ARM: 7769/1: Cortex-A15: fix erratum 798181 implementation ARM: 7768/1: prevent risks of out-of-bound access in ASID allocator ARM: 7767/1: let the ASID allocator handle suspended animation ARM: 7766/1: versatile: don't mark pen as __INIT ARM: 7765/1: perf: Record the user-mode PC in the call chain.

| | * | ARM: 7777/1: Avoid extra calls to the C compilerDouglas Anderson2013-06-291-25/+31

Though these calls don't individually take a lot of time, they add up. Rearrange the ARM Makefile a bit to avoid extra calls to the compiler when they can be easily avoided. When running with the Chrome OS ARM cross compiler "armv7a-cros-linux-gnueabi-", this shaved .55 seconds (from 5.31 seconds to 4.76 seconds) off an incremental build of the kernel: time make -j32 ARCH=arm CROSS_COMPILE=armv7a-cros-linux-gnueabi- Thanks to Mike Frysinger for the clean trick to make this work.

The SOC support is available in mach-sti which contains support code for STiH415, STiH416 SOCs including the generic board support.

Like last time, Renesas sh-mobile is now the platform with the most changes, followed by OMAP and EXYNOS. Two new platforms, TI Keystone and Rockchips RK3xxx are added in this branch, both containing almost no platform specific code at all, since they are using generic subsystem interfaces for clocks, pinctrl, interrupts etc. The device drivers are getting merged through the respective subsystem maintainer trees. One more SoC (u300) is now multiplatform capable and several others (shmobile, exynos, msm, integrator, kirkwood, clps711x) are moving towards that goal with this series but need more work. Also noteworthy is the work on PCI here, which is traditionally part of the SoC specific code. With the changes done by Thomas Petazzoni, we can now more easily have PCI host controller drivers as loadable modules and keep them separate from the platform code in drivers/pci/host. This has already led to the discovery that three platforms (exynos, spear and imx) are actually using an identical PCIe host controller and will be able to share a driver once support for spear and imx is added." * tag 'soc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (480 commits) ARM: integrator: let pciv3 use mem/premem from device tree ARM: integrator: set local side PCI addresses right ARM: dts: Add pcie controller node for exynos5440-ssdk5440 ARM: dts: Add pcie controller node for Samsung EXYNOS5440 SoC ARM: EXYNOS: Enable PCIe support for Exynos5440 pci: Add PCIe driver for Samsung Exynos ARM: OMAP5: voltagedomain data: remove temporary OMAP4 voltage data ARM: keystone: Move CPU bringup code to dedicated asm file ARM: multiplatform: always pick one CPU type ARM: imx: select syscon for IMX6SL ARM: keystone: select ARM_ERRATA_798181 only for SMP ARM: imx: Synertronixx scb9328 needs to select SOC_IMX1 ARM: OMAP2+: AM43x: resolve SMP related build error dmaengine: edma: enable build for AM33XX ARM: edma: Add EDMA crossbar event mux support ARM: edma: Add DT and runtime PM support to the private EDMA API dmaengine: edma: Add TI EDMA device tree binding arm: add basic support for Rockchip RK3066a boards arm: add debug uarts for rockchip rk29xx and rk3xxx series arm: Add basic clocks for Rockchip rk3066a SoCs ...

This is dominated largely by the Samsung platforms (s3c, s5p, exynos) and a few of the others moving code out of arch/arm into more appropriate subsystems. The clocksource and irqchip drivers are now abstracted to the point where platforms that are already cleaned up do not need to even specify the driver they use, it can all get configured from the device tree as we do for normal device drivers. The clocksource changes basically touch every single platform in the process. We further clean up the use of platform specific header files here, with the goal of turning more of the platforms over to being "multiplatform" enabled, which implies that they cannot expose their headers to architecture independent code any more. It is expected that no functional changes are part of the cleanup.

This is probably also a desired side effect of depopulating the arch/arm directory of drivers. Luckily we have just deleted all the <plat/*> include files prior to this so by moving the last one we may delete the directory.

Remove what is upstream for now, until the out-of-tree implementation is in suitable form for merging. An important side effect of this patch is that it allows the building of a Zynq kernel without running into unresolved symbol problems: drivers/built-in.o: In function `amba_get_enable_pclk': clkdev.c:(.text+0x444): undefined reference to `clk_enable' drivers/built-in.o: In function `amba_remove': clkdev.c:(.text+0x488): undefined reference to `clk_disable' drivers/built-in.o: In function `amba_probe': clkdev.c:(.text+0x540): undefined reference to `clk_disable' drivers/built-in.o: In function `amba_device_add': clkdev.c:(.text+0x77c): undefined reference to `clk_disable' drivers/built-in.o: In function `enable_clock': clkdev.c:(.text+0x29738): undefined reference to `clk_enable' drivers/built-in.o: In function `disable_clock': clkdev.c:(.text+0x29778): undefined reference to `clk_disable' drivers/built-in.o: In function `__pm_clk_remove': clkdev.c:(.text+0x297f8): undefined reference to `clk_disable' drivers/built-in.o: In function `pm_clk_suspend': clkdev.c:(.text+0x29bc8): undefined reference to `clk_disable' drivers/built-in.o: In function `pm_clk_resume': clkdev.c:(.text+0x29c28): undefined reference to `clk_enable' make[2]: *** [vmlinux] Error 1 make[1]: *** [sub-make] Error 2 make: *** [all] Error 2 In addition, eliminate Zynq's "use" of the versatile platform, as it is no longer needed. As Nick Bowler points out: For the record, I think this was introduced by commit 56a34b03ff427 ("ARM: versatile: Make plat-versatile clock optional") which forgot to select PLAT_VERSATILE_CLOCK on Zynq. This is not all that surprising, because the fact that Zynq "uses" PLAT_VERSATILE is secretly hidden in the Makefile. Nevertheless, the only feature from versatile that Zynq needed was the clock support, so this patch should *also* delete the secret use of plat-versatile by removing this line from arch/arm/Makefile: plat-$(CONFIG_ARCH_ZYNQ) += versatile Signed-off-by: Josh Cartwright <josh.cartwright@ni.com> Cc: John Linn <john.linn@xilinx.com> Acked-by: Arnd Bergmann <arnd@arndb.de> Tested-by: Michal Simek <michal.simek@xilinx.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's really unnecessary to have plat-mxc, and let's merge it into mach-imx. It's pretty much just a bunch of file renaming and Kconfig/Makefile merge. To make the change less invasive, we keep using Kconfig symbol CONFIG_ARCH_MXC for mach-imx sub-architecture.

| | | * ARM: 7592/1: nommu: prevent generation of kernel unaligned memory accessesWill Deacon2012-12-071-0/+1
| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent ARMv7 toolchains assume that unaligned memory accesses will not fault and will instead be handled by the processor. For the nommu case (without an MPU), memory will be treated as strongly-ordered and therefore unaligned accesses may fault regardless of the SCTLR.A setting. This patch passes -mno-unaligned-access to GCC when compiling for nommu targets, preventing the generation of unaligned memory access in the kernel.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current rules have the .dtb files build in a different directory from the .dts files. The only reason for this is that it was what PowerPC has done historically. This patch changes ARM to use the generic dtb rule which builds .dtb files in the same directory as the source .dts.

* | ARM: pass -marm to gcc by default for both C and assemblerArnd Bergmann2012-10-091-6/+7
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | The Linaro cross toolchain and probably others nowadays default to building in THUMB2 mode. When building a kernel for a CPU that does not support THUMB2, the compiler complains about incorrect flags. We can work around this by setting -marm for all non-T2 builds. -marm was passed unconditionally for C files previously, but nothing was passed to the gcc frontend when processing .S files, resulting in a warning. The assembler never defaults to ARM unless -Wa,-mthumb is supplied explicitly, so the files were still assembled correctly. This patch makes sure that -marm is passed for .S files too, and also avoids the redundant gcc -marm -mthumb in Thumb kernels. Without this patch, building assabet_defconfig results in: usr/initramfs_data.S:1:0: warning: target CPU does not support THUMB instructions [enabled by default] arch/arm/nwfpe/entry.S:1:0: warning: target CPU does not support THUMB instructions [enabled by default] firmware/cis/PCMLM28.cis.gen.S:1:0: warning: target CPU does not support THUMB instructions [enabled by default] (and many more) Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Nicolas Pitre <nico@linaro.org> Acked-by: Dave Martin <dave.martin@linaro.org> Cc: Russell King <rmk+kernel@arm.linux.org.uk>
