[PATCH 2/2] X86/kdump: fall back to reserve high crashkernel memory

2019-04-20 Thread Dave Young
crashkernel=xM tries to reserve crashkernel memory under 4G, which is enough for usual cases. But this could fail sometimes, for example one tries to reserve a big chunk like 2G, it is possible to fail. So let the crashkernel=xM just fall back to use high memory in case it fails to find a suitabl
