Commit fd7d58f0 ("ARM: multi_v7_defconfig: renormalize based on recent additions") removed explicit enable line for CONFIG_DEBUG_FS, because that feature has been selected by other enabled options: CONFIG_TRACING, which were enabled by CONFIG_PERF_EVENTS. In meantime, commit 0e4a459f ("tracing: Remove unnecessary DEBUG_FS dependency") removed the dependency between CONFIG_DEBUG_FS and CONFIG_TRACING, so CONFIG_DEBUG_FS is no longer enabled in default builds. Enable it again explicitly, as debugfs support is essential for various automated testing tools. Link: https://lore.kernel.org/r/20191206125112.11006-1-m.szyprowski@samsung.comSigned-off-by:

32-bit version of sparc has three-level page tables and can use pgtable-nopud and folding of the upper layers. Replace usage of include/asm-generic/4level-fixup.h with include/asm-generic/pgtable-nopud.h and adjust page table manipulation macros and functions accordingly.

Patch series "mm: remove __ARCH_HAS_4LEVEL_HACK", v13. These patches convert several architectures to use page table folding and remove __ARCH_HAS_4LEVEL_HACK along with include/asm-generic/4level-fixup.h. For the nommu configurations the folding is already implemented by the generic code so the only change was to use the appropriate header file. As for the rest, the changes are mostly about mechanical replacement of pgd accessors with pud/pmd ones and the addition of higher levels to page table traversals. With Vineet's patches from "elide extraneous generated code for folded p4d/pud/pmd" series [1] there is a small shrink of the kernel size of about -0.01% for the defconfig builds. This patch (of 13): It is not likely alpha will have 5-level page tables. Replace usage of include/asm-generic/4level-fixup.h and implied __ARCH_HAS_4LEVEL_HACK with include/asm-generic/pgtable-nopud.h and adjust page table manipulation macros and functions accordingly.

There is no need to split some of the lines. However, improve the style of multi-line comment. On top of this there is no need to have double space.
