> 
> Commit ab0e7f20768a ("Documentation: Merge x86-specific boot options doc
> into kernel-parameters.txt") introduced a formatting regression where
> architecture tags were placed on separate lines with broken indentation.
> This caused the 'nopt' [X86] parameter to appear as if it belonged to the
> [PPC/POWERNV] section.
> 
> Furthermore, since the main 'iommu=' parameter heading already specifies it is
> for [X86, EARLY], the subsequent standalone [X86] tags for 'pt', 'nopt', and the
> AMD GART options are redundant and clutter the documentation.
> 
> Clean up the formatting by removing these redundant tags and properly
> attributing the 'nobypass' option to [PPC/POWERNV].
