From 09f98a825a821f7a3f1b162f9ed023f37213a63b Mon Sep 17 00:00:00 2001 From: Tang Liang Date: Fri, 9 Dec 2011 10:05:54 +0800 Subject: x86, acpi, tboot: Have a ACPI os prepare sleep instead of calling tboot_sleep. The ACPI suspend path makes a call to tboot_sleep right before it writes the PM1A, PM1B values. We replace the direct call to tboot via an registration callback similar to __acpi_register_gsi.
