From f10cd522c5fbfec9ae3cc01967868c9c2401ed23 Mon Sep 17 00:00:00 2001 From: Stefano Stabellini Date: Tue, 6 Sep 2011 17:41:47 +0100 Subject: [PATCH] xen: disable PV spinlocks on HVM PV spinlocks cannot possibly work with the current code because they are enabled after pvops patching has already been done, and because PV spinlocks use a different data structure than native spinlocks so we cannot switch between them dynamically. A spinlock that has been taken once by the native code (__ticket_spin_lock) cannot be taken by __xen_spin_lock even after it has been released.
