+Subject: [PATCH] VyOS: build a linux-perf Debian package alongside the kernel
+
+The upstream "make bindeb-pkg" target stopped emitting a perf package
+quite a while ago. Re-add it by hooking into the new builddeb / mkdebian
+infrastructure:
+
+  * mkdebian: emit a "linux-perf-${KERNELRELEASE}" stanza in
+    debian/control whenever the architecture is not user-mode-linux.
+  * scripts/package/debian/rules: add a "binary-perf" target so the
+    binary build loop processes the new package.
+  * builddeb: add an install_perf() helper that invokes
+    "make -C tools/perf install" with prefix=/usr and DESTDIR pointing
+    at the package staging directory, plus a dispatch case for
+    "linux-perf-*" packages.
+
+Refreshed for Linux 6.18.x: the old patch targeted the previous loop
+based scripts/package/builddeb (one-shot builddeb invocation that
+iterated over every package); since v6.7 the package build is driven
+per-package from debian/rules, so we have to extend that mechanism
+instead.
