Hi!
I'd like to backport this changes to fix crash happens on memory mapped file operations.  The patch applies almost cleanly except stubGenerator_arm.cpp due to miss of JEP 340 (One AArch64 Port, Not Two), and some copyright year conflicts. 
Need to note that a series of follow up is required to fix some platforms build. Particularly arm32/aarch64 is not buildable without 8226871. I'll create necessary PR soon. 
Tested with tier1/tier2 and new InternalErrorTest.
