Now different platforms may have different SECTION_SIZE_BITS and MAX_PHYSMEM_BITS. But linux passes nothing related to the vmcore.
User space tools such as makedumpfile needs these to deal with the vmcore. So we must define these when compiling. So if we deal with aother vmcore. We may need to recompile the tools.
These patch series make kernel pass related infomation to the user space tools, via vmcore. And makedumpfile can get these when parsing vmcore. So the makdumpfile becomes more compatible to vmcore with different section size.
Liu Hua (1): kdump: add sparse memory related values to vmcore makedumpfile: get additional information from vmcore
