Merge tag 'riscv-for-linus-5.8-mw1' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux

Pull more RISC-V updates from Palmer Dabbelt:

 - Kconfig select statements are now sorted alphanumerically

 - first-level interrupts are now handled via a full irqchip driver

 - CPU hotplug is fixed

 - vDSO calls now use the common vDSO infrastructure
