The patch titled Subject: arm64: mm: display non-present entries in ptdump has been removed from the -mm tree. Its filename was arm64-mm-display-non-present-entries-in-ptdump.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Steven Price <steven.price@xxxxxxx> Subject: arm64: mm: display non-present entries in ptdump Previously the /sys/kernel/debug/kernel_page_tables file would only show lines for entries present in the page tables. However it is useful to also show non-present entries as this makes the size and level of the holes more visible. This aligns the behaviour with x86 which also shows holes.
