[RFC PATCH 0/2] transfer sparse memory related values

[Liu Hua]

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
