From d2374aecda3f6c9b0d13287027132a37311da300 Mon Sep 17 00:00:00 2001 From: Jack Steiner Date: Wed, 9 Sep 2009 10:41:05 -0500 Subject: [PATCH] x86: SGI UV: Fix IPI macros The UV BIOS has changed the way interrupt remapping is being done. This affects the id used for sending IPIs. The upper id bits no longer need to be masked off.
