[PATCH 1/3] Documentation/admin-guide: kernel-parameters: update CMA entries

[Randy Dunlap]

Add qualifying build option legend [CMA] to kernel boot options
that requirce CMA support to be enabled for them to be usable.

Also capitalize 'CMA' when it is used as an acronym.

[PATCH 2/3] Documentation/admin-guide: kernel-parameters: hyphenate comma-separated

[Randy Dunlap]

When "comma separated" is used as a compound adjective, it should be
hyphenated.

[PATCH 3/3] Documentation/admin-guide: kernel-parameters: add early_param() to list of types of boot parameters

[Randy Dunlap]

early_param() is missing from the list of types of kernel command line
parameters that are listed in kernel-parameters.txt, so add it
(so that I can find parameters more easily).

This doesn't apply to docs-next; it seems you're fixing 5.10 stuff in
linux-next that went through Christoph's tree?  So this patch will need to
go to him.

Thanks,
