This occured since getting the vmalloc area base address doesn't work in
crash now, due to 'vmap_area_list' being removed in the linux kernel
with
below commit (in linux-next tree):
commit 378eb24a0658dd922b29524e0ce35c6c43f56cba
mm/vmalloc: remove vmap_area_list
As an alternative, the commit introduced 'VMALLOC_START' in
vmcoreinfo to
get base address of vmalloc area, use it to return vmallow start address
instead of depending on vmap_area_list and vmlist
LGTM.
