[PATCH -v3 0/4] x86, kdump: Fix crashkernel high with old kexec-tools

2013-04-04 Thread Yinghai Lu
Vivek found some problems with old kexec-tools. We keep the old crashkernel=X to old behavoir, so it will not break old kexec-tools. Add crashkernel=X,high to support new kexec-tools that supports loading high. when high is used, memblock will search from top to low. if the allocated one is above
