From dfbb18bcf6bf36c96b4e51d05b285a2d50ab61a9 Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Sat, 7 May 2016 07:46:24 -0700 Subject: [PATCH] x86: acpi: Change fill_header() Rename fill_header() to acpi_fill_header() for consistency. Change its signature to remove the 'length' parameter and make it a public API. Also remove the unnecessary include files, and improve the AmlCode[] comment a little bit.
