    x86: Document linker script ASSERT() quirk · a5912f6b
    Ingo Molnar authored
    Older binutils breaks if ASSERT() is used without a sink
    for the output.
    
    For example 2.14.90.0.6 is known to be broken, the link
    fails with:
    
      LD      .tmp_vmlinux1
      ld:arch/x86/kernel/vmlinux.lds:678: parse error
    
    Document this quirk in all three files that use it.
