Description of changes:


[4.3.0-55.el6.47.55 ]
- x86/kexec: fix kexec on systems which boot in x2apic mode
   Moving straight from fully disabled to x2apic mode is an illegal state
   transition, and causes an unconditional #GP fault.  Bounce through 
xapic mode
   to avoid the fault.
   In addition, avoid bouncing through the various apic modes if the mode is
   already correct.
