Subject: [PATCH 00/14] x86: disable virt on kdump and emergency_restart

Hi,

This is a new version of the series to disabling virtualization on kdump,
now extended to do the same tricks on emergency_restart() if needed.

This series is against linux-next-20081103.

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.

Patches 08 adds the virt_disable function registering interface, like
the previous series.

Patch 09 hooks emergency_virt_disable() into kdump crash_shutdown code.

Patch 10 hooks emergency_virt_disable() into emergency_restart() using
nmi_shootdown_cpus().

Patches 11-15 change KVM so that it registers a virt_disable function
when loading.

Finally, patch 16 restore the previous reboot=kbd default.
