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()
