Hi Andrew,
After merging the akpm tree, today's linux-next build (powerpc
allyesconfig) failed like this:
drivers/base/firmware_loader/fallback.c: In function 'map_fw_priv_pages':

Maybe caused by patch
"headers: untangle kmemleak.h from mm.h"
Anyway this file should explicitly include linux/vmalloc.h since it uses
stuff in there, so I have added the following patch for today (I think
this could just be applied to the driver-core tree ...):

Subject: [PATCH] firmware: explicitly include vmalloc.h
After some other include file changes, fixes:
