x86, percpu: fix kexec with vmlinux
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
