Documentation/kernel-parameters.txt: document libata's ignore_hpa option
By default the kernel honors the HPA (host protected area) of hard drives. Using libata's ignore_hpa module option it's possible to change this behaviour. Document usage and options of libata.ignore_hpa in Documentation/kernel-parameters.txt. Signed-off-by: Michael Prokop <mika@grml.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
