I'm sending the two patches independently from my core scheduling series as they should be considered even without core scheduling. Changes in V2: - original patch 1 dropped, as already applied - new patch 1 removing dead coding and unneeded pinning - addressed various comments in patch 2 Juergen Gross (2): xen/x86: cleanup unused NMI/MCE code xen: merge temporary vcpu pinning scenarios xen/arch/x86/pv/traps.c | 88 ++++++++---------------------------------- xen/arch/x86/traps.c | 10 +---- xen/common/domain.c | 4 +- xen/common/domctl.c | 2 +- xen/common/schedule.c | 46 +++++++++++++++------- xen/common/wait.c | 30 +++++--------- xen/include/asm-x86/pv/traps.h | 8 ++-- xen/include/asm-x86/softirq.h | 2 +- xen/include/xen/sched.h | 10 ++--- 9 files changed, 72 insertions(+), 128 deletions(-)
