[Xen-devel] [PATCH] dom0 panic on xen-pae when dom0_mem=4096M

["Charles Coffing" <ccoffing@xxxxxxxxxx>]

When running on xen-pae, if you attempt to assign 4 GB of RAM to dom0 using 
"dom0_mem=4096M", a calculation wraps around to 0 and causes dom0 to panic 
early in the boot.

It appears that this problem was already fixed in the user-space domain 
builder.  The attached patch brings the same fix into 
xen/arch/x86/domain_build.c.

Please apply to -3.0.3 and -unstable.
