Pull Tile arch updates from Chris Metcalf: "These changes bring in a bunch of new functionality that has been maintained internally at Tilera over the last year, plus other stray bits of work that I've taken into the tile tree from other folks. The changes include some PCI root complex work, interrupt-driven console support, support for performing fast-path unaligned data fixups by kernel-based JIT code generation, CONFIG_PREEMPT support, vDSO support for gettimeofday(), a serial driver for the tilegx on-chip UART, KGDB support, more optimized string routines, support for ftrace and kprobes, improved ASLR, and many bug fixes. We also remove support for the old TILE64 chip, which is no longer buildable" * git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile: (85 commits) tile: refresh tile defconfig files tile: rework <asm/cmpxchg.h> tile PCI RC: make default consistent DMA mask 32-bit tile: add null check for kzalloc in tile/kernel/setup.c tile: make __write_once a synonym for __read_mostly tile: remove support for TILE64 tile: use asm-generic/bitops/builtin-*.h tile: eliminate no-op "noatomichash" boot argument tile: use standard tile_bundle_bits type in traps.c tile: simplify code referencing hypervisor API addresses tile: change <asm/system.h> to <asm/switch_to.h> in comments tile: mark pcibios_init() as __init tile: check for correct compiler earlier in asm-offsets.c tile: use standard 'generic-y' model for <asm/hw_irq.h> tile: use asm-generic version of <asm/local64.h> tile PCI RC: add comment about "PCI hole" problem tile: remove DEBUG_EXTRA_FLAGS kernel config option tile: add virt_to_kpte() API and clean up and document behavior tile: support FRAME_POINTER tile: support reporting Tilera hypervisor statistics ...
