From 8785c67663b6ba023c7c6d61d37d8e08c00d86a8 Mon Sep 17 00:00:00 2001 From: David Vrabel Date: Mon, 23 Sep 2013 12:52:21 +0100 Subject: [PATCH] xen/x86: set VIRQ_TIMER priority to maximum Commit bee980d9e (xen/events: Handle VIRQ_TIMER before any other hardirq in event loop) effectively made the VIRQ_TIMER the highest priority event when using the 2-level ABI. Set the VIRQ_TIMER priority to the highest so this behaviour is retained when using the FIFO-based ABI.
