A couple more MIPS fixes for 4.18:

Browse source

- 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.
