Hi all,
After merging the akpm tree, today's linux-next build (sparc64 defconfig)
failed like this:
In file included from arch/sparc/include/asm/page_64.h:130:0,

^~~~~~~~
Caused by commit
51bbf54b3f26 ("sparc64: add the missing pgd_page definition")
I don't see a simple way to fix this, so sparc64 is broken for today :-(
