+Subject: [PATCH] MIPS: BCM77xx: Remove legacy __cpuinit{,data} sections that
+ crept in
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+We removed __cpuinit support (leaving no-op stubs) quite some time ago.
+However a few more crept in as of commit 6ee1d93455384cef8a0426effe85da2
+("MIPS: BCM47XX: Detect more then 128 MiB of RAM (HIGHMEM)")
+
+Since we want to clobber the stubs soon, get this removed now.
