arc: mm: add p?d_leaf() definitions

2020-02-04T03:05:24+00:00

walk_page_range() is going to be allowed to walk page tables other than those of user space. For this it needs to know when it has reached a 'leaf' entry in the page tables. This information will be provided by the p?d_leaf() functions/macros. For arc, we only have two levels, so only pmd_leaf() is needed.

mm/vmalloc: Add empty headers and use them from

2019-12-10T09:12:55+00:00

In the x86 MM code we'd like to untangle various types of historic header dependency spaghetti, but for this we'd need to pass to the generic vmalloc code various vmalloc related defines that customarily come via the low level arch header. Signed-off-by: Ingo Molnar

Commit 6aae3425aa9c ("ARC: mm: remove __ARCH_USE_5LEVEL_HACK") make ARC paging code 5-level compliant but left behind a stale define of __ARCH_USE_5LEVEL_HACK in arch/arc/include/asm/hugepage.h. Remove it. Signed-off-by: Mike Rapoport Signed-off-by: Vineet Gupta
