[PATCH] i386/x86-64: Remove un/set_nmi_callback and reserve/release_lapic_nmi functions
Removes the un/set_nmi_callback and reserve/release_lapic_nmi functions as
they are no longer needed. The various subsystems are modified to register
with the die_notifier instead.
Also includes compile fixes by Andrew Morton.
