I've slightly improved the patch. Changes:
- More sane timeouts on ATA commands
- Print a security usage if parameters are illegal
- Extended the manual page with some examples and notes about which
commands are lethal to mounted filesystems
- Teach the kernel about the ATA Security command codes (for console
printf messages)
Even with the kernel changes, a kernel rebuild is not required in order
to test the code.
