+Subject: [PATCH] x86: work around build issue with GNU ld 2.37
+
+I suspect it is commit 40726f16a8d7 ("ld script expression parsing")
+which broke the hypervisor build, by no longer accepting section names
+with a dash in them inside ADDR() (and perhaps other script directives
+expecting just a section name, not an expression): .note.gnu.build-id
+is such a section.
+
+Quoting all section names passed to ADDR() via DECL_SECTION() works
+around the regression.
