From: Paul Bolle <pebolle@tiscali.nl>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit 298589b1cb626adf4beba6dd8e3cd4b64e8799be upstream.
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.
