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
Adrian Hunter (2): efi/unaccepted: Do not let /proc/vmcore try to access unaccepted memory proc/kcore: Do not try to access unaccepted memory
