Subject: linux-next: build failure after merge of the akpm tree

Hi Andrew,

After merging the akpm tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

drivers/base/memory.c: In function 'memory_block_change_state':
drivers/base/memory.c:306:22: error: 'struct memory_block' has no member named 'sysdev'
drivers/base/memory.c:309:22: error: 'struct memory_block' has no member named 'sysdev'

Caused by commit 2691cc121386 ("kdump: add udev events for memory
online/offline") interacting with commit 10fbcf4c6cb1 ("convert 'memory'
sysdev_class to a regular subsystem") from the driver-core tree.

I have added the following merge fix patch for today:
