"These are mostly nohz_full changes, plus a smattering of minor fixes
(notably a couple for ftrace)"
* git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile:
tile: nohz: warn if nohz_full uses hypervisor shared cores
tile: ftrace: fix function_graph tracer issues
tile: map data region shadow of kernel as R/W
tile: support CONTEXT_TRACKING and thus NOHZ_FULL
tile: support arch_irq_work_raise
arch: tile: fix null pointer dereference on pt_regs pointer
tile/elf: reorganize notify_exec()
tile: use si_int instead of si_ptr for compat_siginfo
