Can we support small vmcore ?

for qcom ramdump， it's not a standard vmcore, we need convert the ramdump to vmcore, can we support load small vmcore which not fill the whole PT_LOAD data, like crash utility, it can read data by fd, the vmcore not really contain PT_LOAD data, in this case, we only fill a small vmcore. --------------- PT_LOAD -------ref---> DDRCS0_0.BIN --------------- PT_LOAD -------ref---> DDRCS1_0.BIN ---------------
