Subject: [PATCH v2 0/3] x86/idt: Minor alloc_intr_gate() sanitization

This series is a successor of "[PATCH] x86/idt: Keep spurious entries unset
in system_vectors".

The original issue I tried to address was that /proc/interrupts output
was always containing all possible system vectors, including non allocated
ones (e.g. 'Hypervisor callback interrupts' on bare metal). Thomas
suggested to expand this cosmetic change to making alloc_intr_gate()
__init.

Vitaly Kuznetsov (3):
  x86/xen: Split HVM vector callback setup and interrupt gate allocation
  x86/idt: Annotate alloc_intr_gate() with __init
  x86/idt: Keep spurious entries unset in system_vectors
