Subject: [PATCH 0/3] Do not map unaccepted memory

Hi

Support for unaccepted memory was added recently, refer commit
dcdfdd40fa82 ("mm: Add support for unaccepted memory"), whereby
a virtual machine may need to accept memory before it can be used.

Plug a few gaps where RAM is exposed without checking if it is
unaccepted memory.
