From f1bdb523880c7f6990e9e8e50b0fc972ca475e84 Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Fri, 15 May 2009 13:05:16 -0700 Subject: x86, irq: don't call mp_config_acpi_gsi() if update_mptable is not enabled Len expressed concern that the update_mptable feature has side-effects on the ACPI code. Make it sure explicitly that the code only ever gets called if the (default disabled) update_mptable boot quirk option is disabled.
