Building mem.o for 32 bits x86 triggers a GCC warning: drivers/infiniband/hw/cxgb4/mem.c: In function '_c4iw_write_mem_dma_aligned': drivers/infiniband/hw/cxgb4/mem.c:79:25: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] Silence that warning by casting "&wr_wait" to unsigned long before casting it to __be64. That's what _c4iw_write_mem_inline() already does. Signed-off-by: Paul Bolle <pebolle@tiscali.nl> --- 0) Compile tested only (on 32 bit x86): I do not have this hardware. 1) This warning was introduced in v3.10-rc1, through commit 42b6a949903d ("RDMA/cxgb4: Use DSGLs for fastreg and adapter memory writes for T5."). drivers/infiniband/hw/cxgb4/mem.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
