Subject: [PATCH] lrdp-v2: setting kimage_voffset to null In case of
32bit ramdump kimage_voffset will not be used in ramparser. In
upstream kernel 4.14 this variable got added and set to some address.
Due to that in case of 32 bit all calculation went worng. So forcefully
setting to null if it is 32 bit dump
