not invoked either.

The invocation of x86_init.intr_mode_init() will be moved from
native_smp_prepare_cpus() in a follow up patch to solve <INSERT

Can you be a little bit more precise here, please? :-)

That move would cause the invocation of x86_init.intr_mode_init() for XEN
PV platforms. To prevent that, override the default x86_init.
intr_mode_init() callback with a noop().

On which tree does this apply? Would be nice to get a hint against which
source this can be reviewed.

Aah, just found the rest of the series. In case a single patch of a
series isn't stand alone it would be nice to receive at least the cover
letter of the series in order to know what its all about.

Sorry to confuse you, It's my fault.

Thank you for your reply. I understood. will CC the cover letter to
linux-xen and linux-acpi.
