From 53aac44c904abbad9f474f652f099de13b5c3563 Mon Sep 17 00:00:00 2001 From: Thomas Renninger Date: Mon, 1 Oct 2012 00:23:54 +0200 Subject: ACPI: Store valid ACPI tables passed via early initrd in reserved memblock areas A later patch will compare them with ACPI tables that get loaded at boot or runtime and if criteria match, a stored one is loaded.
