Subject: [PATCH] drivers/base: export gpl (un)register_memory_notifier

Drivers like eHEA need memory notifiers in order to 
update their internal DMA memory map when memory is added
to or removed from the system.

Patch for eHEA memory hotplug support that uses these functions:
http://www.spinics.net/lists/netdev/msg54484.html

Signed-off-by: Jan-Bernd Themann <themann@...ibm.com>

 Hi,

 the eHEA patch belongs to a patchset that is usually
 added by Jeff Garzik once this dependency (EXPORTS)
 is resolved.

 Regards,
 Jan-Bernd
