The problem I have with your patch is that it (1) relies on users to
pass a kernel option and (2) leaves machines with "faulty firmware" out
in the cold.  So I'm wondering if we can fix reserve_crashkernel() to
deal with reality that there indeed are broken firmware out there?

If someone is able to come up with a convincing argument why crashkernel
cannot be fixed on such machines, we'd need to start whitelisting known
good firmwares, no?
