From 9ff4cfb3fcfd48b49fdd9be7381b3be340853aa4 Mon Sep 17 00:00:00 2001 From: Carsten Otte Date: Wed, 20 Apr 2011 10:15:36 +0200 Subject: [PATCH] [S390] kvm-390: Let kernel exit SIE instruction on work From: Christian Borntraeger This patch fixes the sie exit on interrupts. The low level interrupt handler returns to the PSW address in pt_regs and not to the PSW address in the lowcore. Without this fix a cpu bound guest might never leave guest state since the host interrupt handler would blindly return to the SIE instruction, even on need_resched and friends.
