From 0e03c643dc9389e61fa484562dae58c8d6e96d63 Mon Sep 17 00:00:00 2001 From: Paolo Abeni Date: Wed, 17 Jul 2024 13:25:06 +0200 Subject: [PATCH] eth: fbnic: fix s390 build. MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Building the fbnic nn s390, yield a build bug: 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_919’ declared with attribute error: FIELD_PREP: value too large for the field The relevant mask is 9 bits wide, and the related value is the cacheline aligned size of struct skb_shared_info. On s390 the cacheline size is 256 bytes, and skb_shared_info minimum size on 64 bits system is 320 bytes. Avoid building the driver for such arch.
