Hi, This is an updated version of the reboot/kdump virtualization disable series that I've sent previously. In short, the x86 and kdump changes are the same as before, except for EXPORT_SYMBOL_GPL, and the KVM parts are completely different. Details of changes since the previous series: - Style fixes suggested by checkpatch - Added local_irq_disable() to nmi_shootdown_cpus() (patch 08) - Use EXPORT_SYMBOL_GPL() on set_virt_disable_func() & clear_virt_disable_func() - Add comments to source code on places where emergency_virt_disable() is called, explaining why. - kvm: Move the set_virt_disable_func() call to vmx.c and svm.c. This made the patch series shorter and removing one level of abstraction. This series is against linux-next-20081105. Patches 01-07 simply move the non-kdump-specific parts of nmi_shootdown_cpus() to reboot.c, so it can be used by emergency_restart(). They should be a no-op in relation to existing code. Patch 08 adds an additional local_irq_disable() to nmi_shootdown_cpus(), in case it is called with IRQs enabled. Patch 09 adds the virt_disable function registering interface, like the previous series. Patch 10 hooks emergency_virt_disable() into kdump crash_shutdown code. Patch 11 hooks emergency_virt_disable() into emergency_restart() using nmi_shootdown_cpus(). Patches 12-14 change KVM so that it registers a virt_disable function when loading. Finally, patch 15 restore the previous reboot=kbd default. -- Eduardo
