Subject: [PATCH 01/14] mm: percpu: unhide pcpu_embed_first_chunk prototype
Date:   Wed, 17 May 2023 15:10:49 +0200

From: Arnd Bergmann <arnd@arndb.de>

This function is called whenever CONFIG_NEED_PER_CPU_EMBED_FIRST_CHUNK
or CONFIG_HAVE_SETUP_PER_CPU_AREA, but only declared when the
former is set:

mm/percpu.c:3055:12: error: no previous prototype for 'pcpu_embed_first_chunk' [-Werror=missing-prototypes]

There is no real point in hiding declarations, so just remove
the #ifdef here.
