LoongArch: Get correct cores_per_package for SMT systems

Browse source

commit b7296f9d5b upstream.

In loongson_sysconf, The "core" of cores_per_node and cores_per_package
stands for a logical core, which means in a SMT system it stands for a
thread indeed. This information is gotten from SMBIOS Type4 Structure,
so in order to get a correct cores_per_package for both SMT and non-SMT
systems in parse_cpu_table() we should use SMBIOS_THREAD_PACKAGE_OFFSET
instead of SMBIOS_CORE_PACKAGE_OFFSET.
