From c05780ef3c190c2dafbf0be8e65d4f01103ad577 Mon Sep 17 00:00:00 2001 From: Palmer Dabbelt Date: Fri, 7 Jul 2023 09:00:51 -0700 Subject: module: Ignore RISC-V mapping symbols too RISC-V has an extended form of mapping symbols that we use to encode the ISA when it changes in the middle of an ELF. This trips up modpost as a build failure, I haven't yet verified it yet but I believe the kallsyms difference should result in stacks looking sane again.
