Merge git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile
* git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile: arch/tile: convert a BUG_ON to BUILD_BUG_ON arch/tile: make ptrace() work properly for TILE-Gx COMPAT mode arch/tile: support new info op generated by compiler arch/tile: minor whitespace/naming changes for string support files arch/tile: enable single-step support for TILE-Gx arch/tile: parameterize system PLs to support KVM port arch/tile: add Tilera's <arch/sim.h> header as an open-source header arch/tile: Bomb C99 comments to C89 comments in tile's <arch/sim_def.h> arch/tile: prevent corrupt top frame from causing backtracer runaway arch/tile: various top-level Makefile cleanups arch/tile: change lower bound on syscall error return to -4095 arch/tile: properly export __mb_incoherent for modules arch/tile: provide a definition of MAP_STACK kmemleak: add TILE to the list of supported architectures. char: hvc: check for error case arch/tile: Add a warning if we try to allocate too much vmalloc memory. arch/tile: update some comments to clarify register usage. arch/tile: use better "punctuation" for VMSPLIT_3_5G and friends arch/tile: Use <asm-generic/syscalls.h> tile: replace some BUG_ON checks with BUILD_BUG_ON checks
