Subject: [Patch]compile error of register_memory()

Hello.

register_memory() becomes double definition in 2.6.20-rc1.
It is defined in arch/i386/kernel/setup.c as static definition in
2.6.19.  But it is moved to arch/i386/kernel/e820.c in 2.6.20-rc1.
And same name function is defined in driver/base/memory.c too.
So, it becomes cause of compile error of duplicate definition if 
memory hotplug option is on.

This patch is to fix it.
