From dbb669872173237612d4f39aa2f742620da6bd57 Mon Sep 17 00:00:00 2001 From: Robert Marko Date: Mon, 8 Jul 2024 09:46:02 +0200 Subject: [PATCH] kernel: fix x86 compilation on macOS Trying to compile x86 or x86_64 on macOS will fail with: openwrt/build_dir/target-x86_64_musl/linux-x86_64/linux-6.6.36/tools/include/linux/rbtree.h:21:10: fatal error: 'linux/stddef.h' file not found After some digging, it seems that we dropped the old 212-tools_portability patch when 6.6 x86 support was added, then Felix added back some parts of it in ("kernel: fix tools build breakage on macos with x86") but trying to build x86 kernels will still fail. So, lets add more of the required changes from the 212-tools_portability patch so that x86 kernels build on macOS.
