Vivek Goyal b9d1e4bd6e [PATCH] x86_64: x86_64 write apic id fix 
o Apic id is in most significant 8 bits of APIC_ID register. Current code
  is trying to write apic id to least significant 8 bits. This patch fixes
  it.

o This fix enables booting uni kdump capture kernel on a cpu with non-zero
  apic id.
