c6x: use pgtable-nopud instead of 4level-fixup

2019-12-05T03:44:15+00:00

c6x is a nommu architecture and does not require fixup for upper layers
of the page tables because it is already handled by the generic nommu
implementation.

Replace usage of include/asm-generic/4level-fixup.h with
include/asm-generic/pgtable-nopud.h

mm: consolidate pgtable_cache_init() and pgd_cache_init()

2019-09-24T22:54:09+00:00

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().
