From: Kefeng Wang
Date: Sun Nov 21 2021 - 04:25:25 EST


When support page mapping percpu first chunk allocator on arm64, we
found there are lots of duplicated codes in percpu embed/page first
chunk allocator. This patchset is aimed to cleanup them and should
no funciton change, only test on arm64.

Kefeng Wang (4):
mm: percpu: Generalize percpu related config
mm: percpu: Add pcpu_fc_cpu_to_node_fn_t typedef
mm: percpu: Add generic pcpu_fc_alloc/free funciton
mm: percpu: Add generic pcpu_populate_pte() function
