Hello,

The series contain some improvements to disconnect_bsp_APIC, which
started as a way to fix the "APIC error on CPU0: 40(00)" error printed
by some Intel boxes on reboot or shutdown. First patch is the fix for
the error, second patch is a cleanup.

Roger Pau Monne (2):
  x86/apic: fix disabling LVT0 in disconnect_bsp_APIC
  x86/apic: simplify disconnect_bsp_APIC setup of LVT{0/1}
