From 06b37b650cf826349677564cb0ff1560ed8e51fc Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 22 Nov 2016 15:21:22 +0100 Subject: [PATCH] marvell: mark mvneta and mvpp2 32-bit only Both of these drivers won't work on 64-bit architectures unless they are redesigned, since they store a virtual address pointer in a 32-bit field of the descriptors: drivers/net/ethernet/marvell/mvneta_bm.c: In function 'mvneta_bm_construct': drivers/net/ethernet/marvell/mvneta_bm.c:103:16: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast] drivers/net/ethernet/marvell/mvpp2.c: In function 'mvpp2_prs_vlan_init': drivers/net/ethernet/marvell/mvpp2.c:2563:32: error: large integer implicitly truncated to unsigned type [-Werror=overflow] This limits the COMPILE_TEST option for the two drivers again to only build them on 32-bit. This seems nicer than shutting up the warnings, in case we ever actually want to use them on 64-bit, as the warnings indicate which parts of the driver are currently broken there.
