x86, vmlinux.lds: unify .text output sections
32 bit x86 had a dedicated .text.head output section,
whereas 64 bit had it all in a single output section.
In the unified version the dedicated .text.head output section
was kept to have full control over the head code.
32 bit:
- Moved definition of _stext to the linker script.
The definition is located _after_ .text.page_aligned as this
is what 32 bit did before.
The ALIGN(8) was introduced so we hit the exact same address
(on the tested config) before and after the move.
I assume that it is a bug that _stext did not cover the
.text.page_aligned section - if this is true it can be fixed
in a follow-up patch (and the ugly ALIGN() can be dropped).
[ Impact: 64-bit: cleanup, 32-bit: use the 64-bit linker script ]
