* git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile: (27 commits) arch/tile: support newer binutils assembler shift semantics arch/tile: fix deadlock bugs in rwlock implementation drivers/edac: provide support for tile architecture tile on-chip network driver: sync up with latest fixes arch/tile: support 4KB page size as well as 64KB arch/tile: add some more VMSPLIT options and use consistent naming arch/tile: fix some comments and whitespace arch/tile: export some additional module symbols arch/tile: enhance existing finv_buffer_remote() routine arch/tile: fix two bugs in the backtracer code arch/tile: use extended assembly to inline __mb_incoherent() arch/tile: use a cleaner technique to enable interrupt for cpu_idle() arch/tile: sync up with <arch/sim.h> and <arch/sim_def.h> changes arch/tile: fix reversed test of strict_strtol() return value arch/tile: avoid a simulator warning during bootup arch/tile: export <asm/hardwall.h> to userspace arch/tile: warn and retry if an IPI is not accepted by the target cpu arch/tile: stop disabling INTCTRL_1 interrupts during hypervisor downcalls arch/tile: fix __ndelay etc to work better arch/tile: bug fix: exec'ed task thought it was still single-stepping ... Fix up trivial conflict in arch/tile/kernel/vmlinux.lds.S (percpu alignment vs section naming convention fix)
