Merge tag 'common/for-v5.4-rc1/cpu-topology' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux into for-next/cpu-topology
Pull in generic CPU topology changes from Paul Walmsley (RISC-V). * tag 'common/for-v5.4-rc1/cpu-topology' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux: MAINTAINERS: Add an entry for generic architecture topology base: arch_topology: update Kconfig help description RISC-V: Parse cpu topology during boot. arm: Use common cpu_topology structure and functions. cpu-topology: Move cpu topology code to common code. dt-binding: cpu-topology: Move cpu-map to a common binding. Documentation: DT: arm: add support for sockets defining package boundaries
