      ARM: defconfig: re-run savedefconfig on multi_v* configs · 30b10c77
      Olof Johansson authored
      This is mostly to reorder the entries as they've moved in the Kconfig
      hierarchies. Doing this periodically (but not very often) simplifies
      conflict resolution for new options, etc.

      snoop_file_poll() is defined as returning 'unsigned int' but the
      .poll method is declared as returning '__poll_t', a bitwise type.
      
      Fix this by using the proper return type and using the EPOLL
      constants instead of the POLL ones, as required for __poll_t.

      There are no architectures that use include/asm-generic/4level-fixup.h
      therefore it can be removed along with __ARCH_HAS_4LEVEL_HACK define.

      Mike Rapoport authored
      The UML port uses 4 and 5 level fixups to support higher level page
      table directories in the generic VM code.
      
      Implement primitives necessary for the 4th level folding, add walks of
      p4d level where appropriate and drop usage of __ARCH_USE_5LEVEL_HACK.

      alpha: use pgtable-nopud instead of 4level-fixup · a73c9489
      Mike Rapoport authored
      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.
