We are seeing build problems on Arm32 and Arm64. On Arm32, for the following configurations:

* clang-17-keystone_defconfig
* clang-17-lkftconfig
* clang-17-mini2440_defconfig
* clang-17-sama5_defconfig
* gcc-8-defconfig
* gcc-8-sama5_defconfig
* gcc-12-defconfig
* gcc-12-lkftconfig
* gcc-12-lkftconfig-debug
* gcc-12-lkftconfig-debug-kmemleak
* gcc-12-lkftconfig-kasan
* gcc-12-lkftconfig-kselftest-kernel
* gcc-12-lkftconfig-kunit
* gcc-12-lkftconfig-libgpiod
* gcc-12-lkftconfig-rcutorture
* gcc-12-sama5_defconfig

Failure looks like this:

Bisection points to:

Then on Arm64 with Clang 17:
