CVE-2026-89904

In the Linux kernel, the following vulnerability has been resolved: LoongArch: Fix acpi_package_ids[] array overflow With LoongArch virt machine, a typical setting is one core per socket, there will max 256 sockets (packages) on one VM. With PPTT acpi table, array acpi_package_ids[] will be overflowed. Here change the array size of acpi_package_ids[] with the max value of MAX_PACKAGES and KVM_MAX_VCPUS.
