[Chris Metcalf]

Linus,

Please pull the following changes for 4.1 from:

   git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile.git HEAD

These are mostly nohz_full changes, plus a smattering of minor fixes
(notably a couple for ftrace).

Chris Metcalf (5):
       tile: use si_int instead of si_ptr for compat_siginfo
       tile: support arch_irq_work_raise
       tile: support CONTEXT_TRACKING and thus NOHZ_FULL
       tile: map data region shadow of kernel as R/W
       tile: nohz: warn if nohz_full uses hypervisor shared cores

Colin Ian King (1):
       arch: tile: fix null pointer dereference on pt_regs pointer

Davidlohr Bueso (1):
       tile/elf: reorganize notify_exec()

Tony Lu (1):
       tile: ftrace: fix function_graph tracer issues
