From 69cdb114a9d0ef83c599d0e47901b96584f2c361 Mon Sep 17 00:00:00 2001 From: zbb Date: Sun, 12 Jul 2015 17:28:31 +0000 Subject: [PATCH] Implement stubs for ACPI PCI routines ACPI driver requires special functions to be provided by machdep code. Add temporary stubs to satisfy the compiler when both "pci" and "acpi" are enabled in the kernel configuration file.
