[OpenRISC] [PATCH v2 00/12] mm: consolidate definitions of page table accessors

Hi,

The low level page table accessors (pXY_index(), pXY_offset()) are
duplicated across all architectures and sometimes more than once. For
instance, we have 31 definition of pgd_offset() for 25 supported
architectures.

Most of these definitions are actually identical and typically it boils
down to, e.g.

static inline unsigned long pmd_index(unsigned long address)
{
return (address >> PMD_SHIFT) & (PTRS_PER_PMD - 1);
}

static inline pmd_t *pmd_offset(pud_t *pud, unsigned long address)
{
return (pmd_t *)pud_page_vaddr(*pud) + pmd_index(address);
}

These definitions can be shared among 90% of the arches provided XYZ_SHIFT,
PTRS_PER_XYZ and xyz_page_vaddr() are defined.

For architectures that really need a custom version there is always
possibility to override the generic version with the usual ifdefs magic.

These patches introduce include/linux/pgtable.h that replaces
include/asm-generic/pgtable.h and add the definitions of the page table
accessors to the new header.

The patches are vs the v5.7-rc5-mmotm-2020-05-13-20-30

v2 changes:
* s/morotola/motorola in the changelog of patch 6
* replace FIXME with a comment about pmf_off and virt_to_kpte in patch 8
* rebase on v5.7-rc5-mmotm-2020-05-13-20-30

Mike Rapoport (12):
mm: don't include asm/pgtable.h if linux/mm.h is already included
mm: introduce include/linux/pgtable.h
mm: reorder includes after introduction of linux/pgtable.h
csky: replace definitions of __pXd_offset() with pXd_index()
m68k/mm/motorola: move comment about page table allocation funcitons
m68k/mm: move {cache,nocahe}_page() definitions close to their user
x86/mm: simplify init_trampoline() and surrounding logic
mm: pgtable: add shortcuts for accessing kernel PMD and PTE
mm: consolidate pte_index() and pte_offset_*() definitions
mm: consolidate pmd_index() and pmd_offset() definitions
mm: consolidate pud_index() and pud_offset() definitions
mm: consolidate pgd_index() and pgd_offset{_k}() definitions
