[PATCH] x86-64: Overlapping program headers in physical addr space fix

o A recent change to vmlinux.ld.S file broke kexec as now resulting vmlinux
  program headers are overlapping in physical address space.

o Now all the vsyscall related sections are placed after data and after
  that mostly init data sections are placed. To avoid physical overlap
  among phdrs, there are three possible solutions.
	- Place vsyscall sections also in data phdrs instead of user
	- move vsyscal sections after init data in bss.
	- create another phdrs say data.init and move all the sections
	  after vsyscall into this new phdr.

o This patch implements the third solution.
