It's not your fault, but perhaps not totally unrelated ;-)
Your commit seems like the direct cause for:
drivers/firmware/memmap.c:240:19: error: conflicting types for 'memmap_init'
arch/ia64/include/asm/pgtable.h:565:17: note: previous declaration of 'memmap_init' was here
It adds
+#include <linux/memcontrol.h>
+#include <linux/mm.h>
to slub_def.h, this makes firmware/memmap.c eventually include
arch/ia64/include/asm/pgtable.h to create the type conflict.
The suggested fix, however, is to rename firmware/memmap.c's local
memmap_init() to a more specific name.
Thanks,
Fengguang
