Subject: acpi/ghes: don't check if physical_address is not zero
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=2e223c5ec1146b61163d3372ac629d9240d57cb1;p=qemu.git

acpi/ghes: don't check if physical_address is not zero

The 'physical_address' value is a faulty page. As such, 0 is
as valid as any other value.
