Rick Edgecombe 00547ef73f mm/mmap: Add shadow stack pages to memory accounting 
The x86 Control-flow Enforcement Technology (CET) feature includes a new
type of memory called shadow stack. This shadow stack memory has some
unusual properties, which requires some core mm changes to function
properly.
