Documentation: efi: remove description of efi=old_map (fb1201ae) · Commits · 戴 / test

The old EFI runtime region mapping logic that was kept around for some time has finally been removed entirely, along with the SGI UV1 support code that was its last remaining user. So remove any mention of the efi=old_map command line parameter from the docs. Cc: Jonathan Corbet <corbet@lwn.net> Cc: linux-doc@vger.kernel.org Signed-off-by:
