[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.
