In asm/crash_core.h, ARCH can provide its own macro definitions to override DEFAULT_CRASH_KERNEL_LOW_SIZE, CRASH_ALIGN, CRASH_ADDR_LOW_MAX, CRASH_ADDR_HIGH_MAX in <linux/crash_core.h> if needed. Later, x86 and arm64 wil support the generic reservaton, so wrap the including into CONFIG_ARCH_HAS_GENERIC_CRASHKERNEL_RESERVATION ifdeffery scope to avoid compiling error in other ARCH-es which doesn't take the generic reservation.
