      x86, percpu: fix kexec with vmlinux · ef3892bd
      Yinghai Lu authored
      Impact: fix regression with kexec with vmlinux
      
      Split data.init into data.init, percpu, data.init2 sections
      instead of let data.init wrap percpu secion.
      
      Thus kexec loading will be happy, because sections will not
      overlap.
      
      Before the patch we have:
      
      Elf file type is EXEC (Executable file)
      Entry point 0x200000
      There are 6 program headers, starting at offset 64
