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
