Re-posting, cc'ing linux-mm as requested:

We are considering removing this printk at boot time from RHEL because
it will confuse customers, encourage them to change the boot parameters
and generate extraneous support calls.  Its documented in
Documentation/kernel-parameters.txt anyway.  Any thoughts???
