Subject: [PATCH 03/12] SFI: document boot param "sfi=off"

From: Feng Tang <feng.tang@...el.com>

"sfi=off" is analogous to "acpi=off"

In practice, "sfi=off" isn't likely to be very useful, for
1. SFI is used only when ACPI is not available
2. Today's SFI systems are not legacy PC-compatible

ie. "sfi=off" on an ACPI-platform is a NO-OP,
and "sfi=off" on an SFI-platform will likely result in boot failure.
