    x86, vmlinux.lds: unify .text output sections · dfc20895
    Sam Ravnborg authored
    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).
