[PATCH 12/12] SFI: add boot-time initialization hooks
From: Len Brown
Date: Wed Jul 08 2009 - 00:17:25 EST
From: Feng Tang <feng.tang@xxxxxxxxx>
There are two SFI boot-time hooks:
sfi_init() maps the SYST using early_ioremap() and validates all the tables.
sfi_init_late() re-maps SYST with ioremap(), and initializes
the ACPI extension, if present.
