2.6.39-stable review patch. If anyone has any objections, please let us know.
------------------ Content-Length: 922 Lines: 28 From: Konrad Rzeszutek Wilk <[email protected]> commit 15bfc094517db2ddf38ca7ed47f3a1c0ad24f7c4 upstream. When we parse the raw E820, the Xen hypervisor can set "E820_RAM" to "E820_UNUSABLE" if the mem=X argument is used. As such we should _not_ consider the E820_UNUSABLE as an 1-1 identity mapping, but instead use the same case as for E820_RAM.
