Subject: [PATCH 0/3] generic hotplug friendly page_is_ram()
Date: Fri, 22 Jan 2010 11:21:02 +0800	[thread overview]
Message-ID: <20100122032102.137106635@intel.com> (raw)

Hi,

This introduces a generic iomem_resource based page_is_ram()
and removes the x86 page_is_ram().

The resource based page_is_ram() is more hotplug friendly, because memory
hotplug only updates resource and leave e820 unchanged.

The first patch changes generic code, however due to tight dependency,
I'd recommend it be included in x86 tree together with the other two.

Thanks,
Fengguang
