Subject: [PATCH] Fix the j-core SOC build.
Date: Sat, 2 Oct 2021 14:32:15 -0500 [thread overview]
Message-ID: <7d559bd1-1f9c-124f-ad4d-c805c049971a@landley.net> (raw)
From: Rob Landley <rob@landley.net>
Commit b67177ecd956 broke the j-core SOC build with a link failure, because
mm/percpu.c function pcpu_post_unmap_tlb_flush() calls flush_tlb_kernel_range()
which is defined under #ifdef CONFIG_MMU.
