[PATCH 0/3] MIPS: Fix arch_trigger_cpumask_backtrace(), clean up output

Paul Burton <paul.burton@xxxxxxxx> · Fri, 22 Jun 2018 10:55:44 -0700

This series switches MIPS to use the generic
nmi_trigger_cpumask_backtrace() infrastructure to back
arch_trigger_cpumask_backtrace(), switching from synchronous to
asynchronous IPIs in the process in order to resolve possible deadlock
conditions. With the generic infrastructure in use we start using the
__cpuidle annotation to clean up its output for idle CPUs.

Applies cleanly atop master as of 894b8c000ae6 ("Merge tag
'for_v4.18-rc2' of
git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs").

Thanks,
    Paul

  MIPS: Call dump_stack() from show_regs()
  MIPS: Use async IPIs for arch_trigger_cpumask_backtrace()
  MIPS: Annotate cpu_wait implementations with __cpuidle
