2340b62f77 kdump: forcibly disable VMX and SVM on machine_crash_shutdown()
We need to disable virtualization extensions on all CPUs before booting
the kdump kernel, otherwise the kdump kernel booting will fail, and
rebooting after the kdump kernel did its task may also fail.

We do it using cpu_emergency_vmxoff() and cpu_emergency_svm_disable(),
that should always work, because those functions check if the CPUs
support SVM or VMX before doing their tasks.

2ddded2138 x86: move nmi_shootdown_cpus() to reboot.c
Impact: make nmi_shootdown_cpus() available to the rest of the x86 platform

Now nmi_shootdown_cpus() is ready to be used by non-kdump code also.
Move it to reboot.c.

8e29478631 x86 kdump: make kdump_nmi_callback() a function ptr on crash_nmi_callback()
Impact: extend nmi_shootdown_cpus() with a callback

The reboot code will use a different function on crash_nmi_callback().
Adding a function pointer parameter to nmi_shootdown_cpus() for that.

a7d41820f6 x86 kdump: extract kdump-specific code from crash_nmi_callback()
Impact: cleanup

The NMI CPU-halting code will be used on non-kdump cases, also
(e.g. emergency_reboot when virtualization is enabled).
