Pull documentation updates from Jonathan Corbet: "Another moderately busy cycle in docsland: - Work on Chinese translations has picked up again. Happily, they are maintaining the existing translations and not just adding new ones. - Some maintenance of the Japanese and Italian translations as well. - The removal of the venerable "dontdiff" file. It has long outlived its usefulness and contained entries ("parse.*") that would actively mask actual source change. - The addition of enforcement information to the code-of-conduct documentation. Along with some build-system fixes and a lot of typo and language fixes" * tag 'docs-6.13' of git://git.lwn.net/linux: (52 commits) Documentation/CoC: spell out enforcement for unacceptable behaviors docs: fix typos and whitespace in Documentation/process/backporting.rst docs/zh_CN: fix one sentence in llvm.rst docs: bug-bisect: add a note about bisecting -next docs/zh_CN: add the translation of kbuild/llvm.rst Documentation: Fix incorrect paths/magic in magic numbers rst Documentation/maintainer-tip: Fix typos Documentation: Improve crash_kexec_post_notifiers description Docs/zh_CN: Translate physical_memory.rst to Simplified Chinese Documentation: admin: reorganize kernel-parameters intro docs/zh_CN: update the translation of process/programming-language.rst docs/zh_CN: update the translation of mm/page_owner.rst docs/zh_CN: update the translation of mm/page_table_check.rst docs/zh_CN: update the translation of mm/overcommit-accounting.rst docs/zh_CN: update the translation of mm/admon/faq.rst docs/zh_CN: update the translation of mm/active_mm.rst docs/zh_CN: update the translation of mm/hmm.rst docs: remove Documentation/dontdiff docs/zh_CN: Add a entry in Chinese glossary Docs/zh_CN: Fix the pfn calculation error in page_tables.rst ...

@@ -29,7 +29,7 @@ address.
With a page granularity of 4KB and a address range of 32 bits, pfn 0 is at
address 0x00000000, pfn 1 is at address 0x00001000, pfn 2 is at 0x00002000
and so on until we reach pfn 0xfffff at 0xfffff000. With 16KB pages pfs are
-at 0x00004000, 0x00008000 ... 0xffffc000 and pfn goes from 0 to 0x3fffff.
+at 0x00004000, 0x00008000 ... 0xffffc000 and pfn goes from 0 to 0x3ffff.
As you can see, with 4KB pages the page base address uses bits 12-31 of the
address, and this is why `PAGE_SHIFT` in this case is defined as 12 and
