Subject: kdump: add vmlist.addr to vmcoreinfo for x86 vmalloc translation.
From: "Ken'ichi Ohmichi" <oomichi@xxxxxxxxxxxxxxxxx>
Add the symbols 'vmlist' and offset 'vm_struct.addr' to the vmcoreinfo[1]
data for i386 vmalloc translation.
makedumpfile[2] needs VMALLOC_START value for distinguishing a vmalloc
address or not, because it should choose suitable translation method. If
applying this patch, makedumpfile will be able to take VMALLOC_START value
from 'vmlist.addr'.
vmcoreinfo[1]:
The vmcoreinfo data has the minimum debugging information only for dump
filtering. makedumpfile[2] uses it to distinguish unnecessary pages and
creates a small dumpfile.
makedumpfile[2]:
dump filtering command
