kexec, vmalloc: export additional vmalloc layer information
Now, vmap_area_list is exported as VMCOREINFO for makedumpfile to get
the start address of vmalloc region (vmalloc_start). The address which
contains vmalloc_start value is represented as below:
vmap_area_list.next - OFFSET(vmap_area.list) + OFFSET(vmap_area.va_start)
However, both OFFSET(vmap_area.va_start) and OFFSET(vmap_area.list)
aren't exported as VMCOREINFO.
So this patch exports them externally with small cleanup.
[akpm@linux-foundation.org: vmalloc.h should include list.h for list_head]
