They are new, but AFAICS they appear because an old macro, ACPI_PTR_DIFF(), has been used for defining a new one, ACPI_PTR_TO_PHYSADDR(), which is now triggering the old warning in a new way. I guess this could be addressed by applying the Arnd's patch at https://patchwork.kernel.org/project/linux-acpi/patch/20210927121338.938994-1-arnd@kernel.org/ , but that's problematic for the upstream. However, I'm wondering if we can do something like the attached patch instead. > -----Original Message----- > From: kernel test robot <lkp@intel.com> > Sent: Tuesday, December 28, 2021 10:30 PM > To: Rafael J.

They are new, but AFAICS they appear because an old macro, ACPI_PTR_DIFF(), has been used for defining a new one, ACPI_PTR_TO_PHYSADDR(), which is now triggering the old warning in a new way. I guess this could be addressed by applying the Arnd's patch at https://patchwork.kernel.org/project/linux-acpi/patch/20210927121338.938994-1-arnd(a)kernel.org/ , but that's problematic for the upstream.

They are new, but AFAICS they appear because an old macro, ACPI_PTR_DIFF(), has been used for defining a new one, ACPI_PTR_TO_PHYSADDR(), which is now triggering the old warning in a new way. I guess this could be addressed by applying the Arnd's patch at https://patchwork.kernel.org/project/linux-acpi/patch/20210927121338.938994-1-arnd(a)kernel.org/ , but that's problematic for the upstream.
