From c19b85216b5d47d922ac010931d4c7b2d79b2f68 Mon Sep 17 00:00:00 2001 From: Eduardo Habkost Date: Thu, 2 Jun 2016 13:46:13 -0300 Subject: [PATCH] target-i386: Remove xlevel & hv-spinlocks option fixups The "fixup will be removed in future versions" warnings are present since QEMU 1.7.0, at least, so users should have fixed their scripts and configurations, already. In the case of libvirt users, libvirt doesn't use the "xlevel" option, and already rejects HyperV spinlock retry count < 0xFFF.
