Ok, but since 'crashkernel=auto' is not used today, nobody has
'crashkernel=auto' in the bootloader configuration. So I don't see any
practial advantage of that config option.

Eric, what's your opinion on that, do we need a config option
CONFIG_KEXEC_AUTO_RESERVE or could we just implement that feature
unconditionally (if CONFIG_KEXEC is enabled, of course).
