- Use async IPIs for arch_trigger_cpumask_backtrace() in order to
avoid warnings & deadlocks, fixing a problem introduced in v3.19
with the fix trivial to backport as far as v4.9.
- Fix ioremap()'s MMU/TLB backed path to avoid spuriously rejecting
valid requests due to an incorrect belief that the memory region is
backed by potentially-in-use RAM. This fixes a regression in v4.2.
