From ef75fc2e63136be4c1194b0802025eab6241c508 Mon Sep 17 00:00:00 2001 From: Olof Johansson Date: Mon, 16 Dec 2019 20:07:04 -0800 Subject: [PATCH] riscv: export flush_icache_all to modules [ Upstream commit 1833e327a5ea1d1f356fbf6ded0760c9ff4b0594 ] This is needed by LKDTM (crash dump test module), it calls flush_icache_range(), which on RISC-V turns into flush_icache_all(). On other architectures, the actual implementation is exported, so follow that precedence and export it here too. Fixes build of CONFIG_LKDTM that fails with: ERROR: "flush_icache_all" [drivers/misc/lkdtm/lkdtm.ko] undefined!
