Merge tag 'percpu-for-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/dennis/percpu
Pull percpu updates from Dennis Zhou: "Enable percpu page allocator for RISC-V. There are RISC-V configurations with sparse NUMA configurations and small vmalloc space causing dynamic percpu allocations to fail as the backing chunk stride is too far apart" * tag 'percpu-for-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/dennis/percpu: riscv: Enable pcpu page first chunk allocator mm: Introduce flush_cache_vmap_early()
