+Subject: [PATCH] rt-tests: oslat: Allow build for not supported archs
+
+Now rt-tests won't build for archs other than x86/i386/ppc64 after oslat is
+merged.  Instead of failing the build, let's make it pass.  However, whenever
+oslat is executed, instead of running the real program, dump an error message,
+so that people can try to implement the frc() function for it when there's a
+real need for the new arch.

-Subject: [PATCH] gzip with -n for build reproducibilty

-The date can get encoded in the header of the gz file, which
-causes the binary files between two different builds of the
