Subject: acpi: Fix table length for QEMU
X-Git-Tag: v2025.04~7^2~4

acpi: Fix table length for QEMU

The end of the ACPI table is set to 'addr' instead of 'end'. The ACPI
code for QEMU relies on those values to mark memory as 'ACPI Reclaim'
and as a result the ACPI RSDP ends up in Boot services Data.
