+Subject: [PATCH] Perf is shipped in debian in linux-tools-$version package
+
+Extend the existing to builddeb script to build perf if BUILD_TOOLS=y is
+added the make deb-pkg line
+
+Some features of this patch I'm uncomfortable with:
+
+1. Relative paths are resoved to absolute ones
+ Especially with separate O= buildd, perf build from tools/perf dir
+ fail.
+
+2. Unsetting LDFLAGS
+ make -> shell (builddeb) -> make expands variables. The LDFLAGS as
+ set by toplevel makefile are for kernel, so we just unset the flag
+ here.
+
+3. Replaces ubuntu/debian packages instead attempting to fit to
+ the linux-base/linux-tools-common frameworks. I think people who
+ want to run "make deb-pkg" for their kernels would rather keep this
+ simple.
+
+4. More tools than just perf could be built - unfortunately most
+ tools fail to have a working "install" target and/or else have
+ build process inconsistent with other tools. A topic for another
+ patch series.
