Pull ARC port updates from Vineet Gupta: "Support for two new platforms based on ARC700: - Abilis TB10x SoC [Chritisian/Pierrick] - Simulator only System-C Model [Mischa] ARC specific MM improvements: - Avoid full TLB flush (ASID increment) on munmap (even single page) - VIPT Cache Flushing improvements + Delayed dcache flush for non-aliasing dcache (big performance boost) + icache flush aliasing agnostic (no need to kill all possible aliases) Others: - Avoid needless rebuild of DTB files for every kernel build - Remove builtin cmdline as that is already provided by DeviceTree/bootargs - Fixing unaligned access emulation corner case - checkpatch fixes [Sachin] - Various fixlets [Noam] - Minor build failures/cleanups" * tag 'arc-v3.10-rc1-part1' of git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc: (35 commits) ARC: [mm] Lazy D-cache flush (non aliasing VIPT) ARC: [mm] micro-optimize page size icache invalidate ARC: [mm] remove the pessimistic all-alias-invalidate icache helpers ARC: [mm] consolidate icache/dcache sync code ARC: [mm] optimise icache flush for kernel mappings ARC: [mm] optimise icache flush for user mappings ARC: [mm] optimize needless full mm TLB flush on munmap ARC: Add support for nSIM OSCI System C model ARC: [TB10x] Adapt device tree to new compatible string ARC: [TB10x] Add support for TB10x platform ARC: [TB10x] Device tree of TB100 and TB101 Development Kits ARC: Prepare interrupt code for external controllers ARC: Allow embedded arc-intc to be properly placed in DT intc hierarchy ARC: [cmdline] Don't overwrite u-boot provided bootargs ARC: [cmdline] Remove CONFIG_CMDLINE ARC: [plat-arcfpga] defconfig update ARC: unaligned access emulation broken if callee-reg dest of LD/ST ARC: unaligned access emulation error handling consolidation ARC: Debug/crash-printing Improvements ARC: fix typo with clock speed ...

ARC: remove #ifdef-ed out include of dead header

There's no (Kconfig) macro CONFIG_BLOCK_DEV_RAM. (CONFIG_BLK_DEV_RAM does exist though.) But linux/blk.h got killed in 2005 anyway (in a patch titled "kill blk.h"), so these three lines can be removed. Signed-off-by: Paul Bolle Signed-off-by: Vineet Gupta

ARC: [DeviceTree] Convert some Kconfig items to runtime values

ARC: [DeviceTree] Basic support

This is minimal infrastructure needed for devicetree work. It uses an a sample "skeleton" devicetree - embedded in kernel image - to print the board, manufacturer by parsing the top-level "compatible" string. As of now we don't need any additional "board" specific "machine_desc".
