Documentation/filesystems/proc.txt

vmallocinfo:

Provides information about vmalloced/vmaped areas. One line per area, containing the virtual address range of the area, size in bytes, caller information of the creator, and optional information depending on the kind of area :

pages=nr number of pages
phys=addr if a physical address was specified
ioremap I/O mapping (ioremap() and friends)
vmalloc vmalloc() area
vmap vmap()ed pages
user VM_USERMAP area
vpages buffer for pages pointers was vmalloced (huge area)
N=nr (Only on NUMA kernels)
Number of pages allocated on memory node
