Subject: ia64: note requirement for 8250_pnp, now that 8250_acpi is gone
From: Bjorn Helgaas <bjorn.helgaas@xxxxxx>
We removed 8250_acpi in 2.6.17. If we don't have PNPACPI turned on, we
won't find any ACPI serial devices, so mention this requirement in the
troubleshooting part of the documentation.
CONFIG_PNPACPI is already turned on in all the relevant defconfigs.
