+Subject: [PATCH] drivers: gpu: drm: msm: registers: improve reproducibility
+
+The files generated by gen_header.py capture the source path to the
+input files and the date.  While that can be informative, it varies
+based on where and when the kernel was built as the full path is
+captured.
+
+Since all of the files that this tool is run on is under the drivers
+directory, this modifies the application to strip all of the path before
+drivers.  Additionally it prints <stripped> instead of the date.
+
+Both changes solve the reproducibility issue.

+Subject: [PATCH] vt/conmakehash: improve reproducibility for v6.10
+
+The file generated by conmakehash capture the application
+path used to generate the file. While that can be informative,
+it varies based on where the kernel was built, as the full
+path is captured.
+
+We tweak the application to use a second input as the "capture
+name", and then modify the Makefile to pass the basename of
+the source, making it reproducible.
+
+This could be improved by using some sort of path mapping,
+or the application manipualing argv[1] itself, but for now
+this solves the reprodicibility issue.
