[PATCH 11/12] mm: Remove callers of pfn_t functionality

All PFN_* pfn_t flags have been removed. Therefore there is no longer a need for the pfn_t type and all uses can be replaced with normal pfns. Signed-off-by: Alistair Popple Reviewed-by: Christoph Hellwig --- arch/x86/mm/pat/memtype.c| 6 +- drivers/dax/device.c

[PATCH 07/12] mm: Remove redundant pXd_devmap calls

DAX was the only thing that created pmd_devmap and pud_devmap entries however it no longer does as DAX pages are now refcounted normally and pXd_trans_huge() returns true for those. Therefore checking both pXd_devmap and pXd_trans_huge() is redundant and the former can be removed without changing b

[PATCH 10/12] mm: Remove devmap related functions and page table bits

Now that DAX and all other reference counts to ZONE_DEVICE pages are managed normally there is no need for the special devmap PTE/PMD/PUD page table bits. So drop all references to these, freeing up a software defined page table bit on architectures supporting it. Signed-off-by: Alistair Popple A

[PATCH 09/12] powerpc: Remove checks for devmap pages and PMDs/PUDs

PFN_DEV no longer exists. This means no devmap PMDs or PUDs will be created, so checking for them is redundant. Instead mappings of pages that would have previously returned true for pXd_devmap() will return true for pXd_trans_huge() Signed-off-by: Alistair Popple --- arch/powerpc/mm/book3s64/ha

[PATCH 08/12] mm/khugepaged: Remove redundant pmd_devmap() check

The only users of pmd_devmap were device dax and fs dax. The check for pmd_devmap() in check_pmd_state() is therefore redundant as callers explicitly check for is_zone_device_page(), so this check can be dropped. Signed-off-by: Alistair Popple --- mm/khugepaged.c | 2 -- 1 file changed, 2 deleti

[PATCH 02/12] mm: Convert pXd_devmap checks to vma_is_dax

Currently dax is the only user of pmd and pud mapped ZONE_DEVICE pages. Therefore page walkers that want to exclude DAX pages can check pmd_devmap or pud_devmap. However soon dax will no longer set PFN_DEV, meaning dax pages are mapped as normal pages. Ensure page walkers that currently use pXd_de

GUP uses pXX_devmap() calls to see if it needs to a get a reference on the associated pgmap data structure to ensure the pages won't go away. However it's a driver responsibility to ensure that if pages are mapped (ie. discoverable by GUP) that they are not offlined or removed from the memmap so th

[PATCH 04/12] mm: Convert vmf_insert_mixed() from using pte_devmap to pte_special

DAX no longer requires device PTEs as it always has a ZONE_DEVICE page associated with the PTE that can be reference counted normally. Other users of pte_devmap are drivers that set PFN_DEV when calling vmf_insert_mixed() which ensures vm_normal_page() returns NULL for these entries. There is no r
