Subject: [PATCH] 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 __week 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().
Signed-off-by: Mike Rapoport <rppt@...ux.ibm.com>
