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 Link: http://lkml.kernel.org/r/1572938135-31886-4-git-send-email-rppt@kernel.org Signed-off-by: Mike Rapoport Cc: Anatoly Pugachev Cc: Anton Ivanov Cc: Arnd Bergmann Cc: "David S.

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().

arch/c6x/include/asm/pgtable.h: define dummy pgprot_writecombine for !MMU

2015-03-13T01:46:08+00:00

When !MMU, asm-generic will not define default pgprot_writecombine, so c6x needs to define it by itself.
