Cover letter [PATCH 0/8] mm: cleanup usage of <asm/pgalloc.h>
From: Mike Rapoport <[email protected]>
Hi,
Most architectures have very similar versions of pXd_alloc_one() and pXd_free_one() for intermediate levels of page table. These patches add generic versions of these functions in <asm-generic/pgalloc.h> and enable use of the generic functions where appropriate.
In addition, functions declared and defined in <asm/pgalloc.h> headers are used mostly by core mm and early mm initialization in arch and there is no actual reason to have the <asm/pgalloc.h> included all over the place. The first patch in this series removes unneeded includes of <asm/pgalloc.h>
In the end it didn't work out as neatly as I hoped and moving pXd_alloc_track() definitions to <asm-generic/pgalloc.h> would require unnecessary changes to arches that have custom page table allocations, so I've decided to move lib/ioremap.c to mm/ and make pgalloc-track.h local to mm/.
Joerg Roedel (1):
mm: move p?d_alloc_track to separate header file
Mike Rapoport (7):
mm: remove unneeded includes of <asm/pgalloc.h>
opeinrisc: switch to generic version of pte allocation
xtensa: switch to generic version of pte allocation
asm-generic: pgalloc: provide generic pmd_alloc_one() and pmd_free_one()
asm-generic: pgalloc: provide generic pud_alloc_one() and pud_free_one()
asm-generic: pgalloc: provide generic pgd_free()
mm: move lib/ioremap.c to mm/
