Merge tag 'arc-v3.11-rc1-part1' of git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc
Pull first batch of ARC changes from Vineet Gupta: "There's a second bunch to follow next week - which depends on commits on other trees (irq/net). I'd have preferred the accompanying ARC change via respective trees, but it didn't workout somehow. Highlights of changes: - Continuation of ARC MM changes from 3.10 including zero page optimization Setting pagecache pages dirty by default Non executable stack by default Reducing dcache flushes for aliasing VIPT config - Long overdue rework of pt_regs machinery - removing the unused word gutters and adding ECR register to baseline (helps cleanup lot of low level code) - Support for ARC gcc 4.8 - Few other preventive fixes, cosmetics, usage of Kconfig helper.. The diffstat is larger than normal primarily because of arcregs.h header split as well as beautification of macros in entry.h" * tag 'arc-v3.11-rc1-part1' of git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc: (32 commits) ARC: warn on improper stack unwind FDE entries arc: delete __cpuinit usage from all arc files ARC: [tlb-miss] Fix bug with CONFIG_ARC_DBG_TLB_MISS_COUNT ARC: [tlb-miss] Extraneous PTE bit testing/setting ARC: Adjustments for gcc 4.8 ARC: Setup Vector Table Base in early boot ARC: Remove explicit passing around of ECR ARC: pt_regs update #5: Use real ECR for pt_regs->event vs. synth values ARC: stop using pt_regs->orig_r8 ARC: pt_regs update #4: r25 saved/restored unconditionally ARC: K/U SP saved from one location in stack switching macro ARC: Entry Handler tweaks: Simplify branch for in-kernel preemption ARC: Entry Handler tweaks: Avoid hardcoded LIMMS for ECR values ARC: Increase readability of entry handlers ARC: pt_regs update #3: Remove unused gutter at start of callee_regs ARC: pt_regs update #2: Remove unused gutter at start of pt_regs ARC: pt_regs update #1: Align pt_regs end with end of kernel stack page ARC: pt_regs update #0: remove kernel stack canary ARC: [mm] Remove @write argument to do_page_fault() ARC: [mm] Make stack/heap Non-executable by default ...
