FWIW, this does not appear to be clang specific, it reproduces with GCC as well: $ make -skj"$(nproc)" ARCH=s390 CROSS_COMPILE=s390-linux- allmodconfig drivers/net/ethernet/meta/fbnic/fbnic_txrx.o In file included from <command-line>: In function 'fbnic_config_drop_mode_rcq', inlined from 'fbnic_enable' at drivers/net/ethernet/meta/fbnic/fbnic_txrx.c:1836:4: include/linux/compiler_types.h:510:45: error: call to '__compiletime_assert_944' declared with attribute error: FIELD_PREP: value too large for the field 510 | _compiletime_assert(condition, msg, __compiletime_assert_, __COUNTER__) | ^ include/linux/compiler_types.h:491:25: note: in definition of macro '__compiletime_assert' 491 | prefix ## suffix(); \ | ^~~~~~ include/linux/compiler_types.h:510:9: note: in expansion of macro '_compiletime_assert' 510 | _compiletime_assert(condition, msg, __compiletime_assert_, __COUNTER__) | ^~~~~~~~~~~~~~~~~~~ include/linux/build_bug.h:39:37: note: in expansion of macro 'compiletime_assert' 39 | #define BUILD_BUG_ON_MSG(cond, msg) compiletime_assert(!(cond), msg) | ^~~~~~~~~~~~~~~~~~ include/linux/bitfield.h:68:17: note: in expansion of macro 'BUILD_BUG_ON_MSG' 68 | BUILD_BUG_ON_MSG(__builtin_constant_p(_val) ? \ | ^~~~~~~~~~~~~~~~ include/linux/bitfield.h:115:17: note: in expansion of macro '__BF_FIELD_CHECK' 115 | __BF_FIELD_CHECK(_mask, 0ULL, _val, "FIELD_PREP: "); \ | ^~~~~~~~~~~~~~~~ drivers/net/ethernet/meta/fbnic/fbnic_txrx.c:1773:13: note: in expansion of macro 'FIELD_PREP' 1773 | FIELD_PREP(FBNIC_QUEUE_RDE_CTL0_MIN_TROOM_MASK, FBNIC_RX_TROOM); | ^~~~~~~~~~ ...
