Subject[PATCH 26/50] x86/boot/e820: Clarify the role of finish_e820_parsing() and rename it to e820__finish_early_params()
Date
finish_e820_parsing() is closely related to parse_early_params(), but the
name does not tell us this clearly, so rename it to e820__finish_early_params().

Also add a few comments to explain what the function does.

No change in functionality.
