4*5c755e9fSBadari PulavartyDescription:
5*5c755e9fSBadari Pulavarty		The /sys/devices/system/memory contains a snapshot of the
6*5c755e9fSBadari Pulavarty		internal state of the kernel memory blocks. Files could be
7*5c755e9fSBadari Pulavarty		added or removed dynamically to represent hot-add/remove
8*5c755e9fSBadari Pulavarty		operations.

16*5c755e9fSBadari PulavartyDescription:
17*5c755e9fSBadari Pulavarty		The file /sys/devices/system/memory/memoryX/removable
18*5c755e9fSBadari Pulavarty		indicates whether this memory block is removable or not.
19*5c755e9fSBadari Pulavarty		This is useful for a user-level agent to determine
20*5c755e9fSBadari Pulavarty		identify removable sections of the memory before attempting
21*5c755e9fSBadari Pulavarty		potentially expensive hot-remove memory operation
