[patch 0/3] Protect crashkernel against BSS overlap

I observed the problem that even when you choose the default 16M as crashkernel base address and the kernel is very big, the reserved area may overlap with the kernel BSS. Currently, this is not checked at runtime, so the kernel just crashes when you load the panic kernel in the sys_kexec call. Th
