Subject: [PATCH] memblock: fix section mismatch
Date: Tue, 5 Jan 2016 12:16:04 +0300 [thread overview]
Message-ID: <1451985364-90757-1-git-send-email-kirill.shutemov@linux.intel.com> (raw)
allmodconfig produces following warning for me:
WARNING: vmlinux.o(.text.unlikely+0x10314): Section mismatch in reference from the function movable_node_is_enabled() to the variable .meminit.data:movable_node_enabled
The function movable_node_is_enabled() references
the variable __meminitdata movable_node_enabled.
This is often because movable_node_is_enabled lacks a __meminitdata
annotation or the annotation of movable_node_enabled is wrong.
Let's mark the function with __meminit. It fixes the warning.
