+Subject: vmlinux.lds.h: add DWARF v5 sections
+
+From: Nick Desaulniers <ndesaulniers@google.com>
+
+commit 3c4fa46b30c551b1df2fb1574a684f68bc22067c upstream.
+
+We expect toolchains to produce these new debug info sections as part of
+DWARF v5. Add explicit placements to prevent the linker warnings from
+--orphan-section=warn.
+
+Compilers may produce such sections with explicit -gdwarf-5, or based on
+the implicit default version of DWARF when -g is used via DEBUG_INFO.
+This implicit default changes over time, and has changed to DWARF v5
+with GCC 11.
+
+.debug_sup was mentioned in review, but without compilers producing it
+today, let's wait to add it until it becomes necessary.
