[PATCH V2 0/2] Do not try to access unaccepted memory

[Adrian Hunter]

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.


Changes in V2:

      efi/unaccepted: Do not let /proc/vmcore try to access unaccepted memory
          Change patch subject and commit message
          Use vmcore_cb->.pfn_is_ram() instead of changing vmcore.c

      proc/kcore: Do not try to access unaccepted memory
          Change patch subject and commit message
          Do not open code pfn_is_unaccepted_memory()

      /dev/mem: Do not map unaccepted memory
          Patch dropped because it is not required
