Date: Fri, 11 Sep 2020 10:44:58 -0400
* gnu/packages/linux.scm (make-linux-libre-source): Rename the UPSTREAM-SOURCE
parameter to LINUX-UPSTREAM-SOURCE. Add a new LINUX-LIBRE-UPSTREAM-SOURCE
parameter. Update doc. Adjust variable names. Capitalize "Linux" in the
user messages. Remove empty directories from the generated sources, then
invoke diff between these sources and those of the corresponding Linux-libre
release, unless LINUX-LIBRE-UPSTREAM-SOURCE is #f.
(%upstream-linux-source): Convert the hash as base32 inside the definition, to
simplify its use.
(%upstream-linux-libre-source): New procedure.
(linux-libre-5.8-pristine-source): Add a LIBRE-HASH binding and use it with
%UPSTREAM-LINUX-LIBRE-SOURCE to provide the Linux-libre release origin to the
make-linux-libre-source procedure call.
(linux-libre-5.4-pristine-source): Likewise.
(linux-libre-4.19-pristine-source): Likewise.
(linux-libre-4.14-pristine-source): Likewise.
(linux-libre-4.9-pristine-source): Likewise.
(linux-libre-4.4-pristine-source): Likewise.
