      Pull libnvdimm fixes from Dan Williams:
       "A fix for a crash scenario that has been present since the initial
        merge, a minor regression in sysfs attribute visibility, and a fix for
        some flexible array warnings.
      
        The bulk of this pull is an update to the libnvdimm unit test
        infrastructure to test non-ACPI platforms. Given there is zero
        regression risk for test updates, and the tests enable validation of
        bits headed towards the next merge window, I saw no reason to hold the
        new tests back. Santosh originally submitted this before the v5.11
        window opened.
      
        Summary:
      
         - Fix a crash when sysfs accesses race 'dimm' driver probe/remove.
      
         - Fix a regression in 'resource' attribute visibility necessary for
           mapping badblocks and other physical address interrogations.
      
         - Fix some flexible array warnings
      
         - Expand the unit test infrastructure for non-ACPI platforms"

      x86/efi: Remove EFI PGD build time checks · 816ef8d7
      Borislav Petkov authored
      With CONFIG_X86_5LEVEL, CONFIG_UBSAN and CONFIG_UBSAN_UNSIGNED_OVERFLOW
      enabled, clang fails the build with
      
        x86_64-linux-ld: arch/x86/platform/efi/efi_64.o: in function `efi_sync_low_kernel_mappings':
        efi_64.c:(.text+0x22c): undefined reference to `__compiletime_assert_354'
      
      which happens due to -fsanitize=unsigned-integer-overflow being enabled:
      
        -fsanitize=unsigned-integer-overflow: Unsigned integer overflow, where
        the result of an unsigned integer computation cannot be represented
        in its type. Unlike signed integer overflow, this is not undefined
        behavior, but it is often unintentional. This sanitizer does not check
        for lossy implicit conversions performed before such a computation
        (see -fsanitize=implicit-conversion).
      
      and that fires when the (intentional) EFI_VA_START/END defines overflow
      an unsigned long, leading to the assertion expressions not getting
      optimized away (on GCC they do)...
      
      However, those checks are superfluous: the runtime services mapping
      code already makes sure the ranges don't overshoot EFI_VA_END as the
      EFI mapping range is hardcoded. On each runtime services call, it is
      switched to the EFI-specific PGD and even if mappings manage to escape
      that last PGD, this won't remain unnoticed for long.
      
      So rip them out.
