From d450c088fb00d5a744b1fe8648a488035a10a03c Mon Sep 17 00:00:00 2001 From: Jacob Pan Date: Thu, 26 Jan 2012 17:32:33 +0000 Subject: [PATCH] x86/mrst: Set ISA bus type for fake MP IRQs We use MP IRQs for SFI presented timer interrupts, we should also set mp_bus_not_pci for MP_ISA_BUS so that pin_2_irq mapping is correct.
