From 782de70c42930baae55234f3df0dc90774924447 Mon Sep 17 00:00:00 2001 From: Mike Rapoport Date: Mon, 23 Sep 2019 15:35:31 -0700 Subject: mm: consolidate pgtable_cache_init() and pgd_cache_init() Both pgtable_cache_init() and pgd_cache_init() are used to initialize kmem cache for page table allocations on several architectures that do not use PAGE_SIZE tables for one or more levels of the page table hierarchy. Most architectures do not implement these functions and use __weak default NOP implementation of pgd_cache_init(). Since there is no such default for pgtable_cache_init(), its empty stub is duplicated among most architectures. Rename the definitions of pgd_cache_init() to pgtable_cache_init() and drop empty stubs of pgtable_cache_init().
