Subject: [PATCH v2] Documentation/kernel-parameters: fix architecture alignment for pt, nopt, and nobypass
Date: Mon, 30 Mar 2026 06:59:57 -0400 [thread overview]
Message-ID: <20260330105957.2271-1-lirongqing@baidu.com> (raw)
From: Li RongQing <lirongqing@baidu.com>
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].
