[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.

Adrian Hunter (3):
      proc/vmcore: Do not map unaccepted memory
      proc/kcore: Do not map unaccepted memory
      /dev/mem: Do not map unaccepted memory

 drivers/char/mem.c |  9 +++++++--
 fs/proc/kcore.c    | 10 +++++++++-
 fs/proc/vmcore.c   | 15 ++++++++++++---
