+From 3e7b32bf2d6042314772249532e80517e9126bc5 Mon Sep 17 00:00:00 2001
+From: Bartosz Dunajski <bartosz.dunajski@intel.com>

+Subject: [PATCH] refactor: use std::numeric_limits to get max value
+
+Newer GCC (16.x) no longer pulls in <climits> transitively, so the use
+of ULONG_MAX failed to build. Upstream replaced ULONG_MAX with
+std::numeric_limits<uint64_t>::max(), which removes the dependency on
+the macro entirely. Backported verbatim to fix the build on the pinned
+releases/25.48 branch.
+
+Upstream-Status: Backport [https://github.com/intel/compute-runtime/commit/3e7b32bf2d6042314772249532e80517e9126bc5]
