      kbuild: warn objects shared among multiple modules · 598afa05
      Masahiro Yamada authored
      If an object is shared among multiple modules, and some of them are
      configured as 'm', but the others as 'y', the shared object is built
      as modular, then linked to the modules and vmlinux. This is a potential
      issue because the expected CFLAGS are different between modules and
      builtins.
      
      Commit 637a642f ("zstd: Fixing mixed module-builtin objects")
      reported that this could be even more fatal in some cases such as
      Clang LTO.
      
      That commit fixed lib/zlib/zstd_{compress,decompress}, but there are
      still more instances of breakage.
      
      This commit adds a W=1 warning for shared objects, so that the kbuild
      test robot, which provides build tests with W=1, will avoid a new
      breakage slipping in.
      
      Quick compile tests on v6.1-rc4 detected the following:

      Since pmd_user_accessible_page() doesn't check if a pmd is leaf, it
      decrease file_map_count for a non-leaf pmd comes from collapse_huge_page().
      and so trigger BUG_ON() unexpectedly.
      
      Fix this problem by using pmd_leaf() insteal of pmd_present() in
      pmd_user_accessible_page(). Moreover, use pud_leaf() for
      pud_user_accessible_page() too.
