Arnd Bergmann 1985a88107 ntb: perf test: fix address space confusion ... The ntb driver assigns between pointers an __iomem tokens, and also casts them to 64-bit integers, which results in compiler warnings on 32-bit systems: drivers/ntb/test/ntb_perf.c: In function 'perf_copy': drivers/ntb/test/ntb_perf.c:213:10: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast] vbase = (u64)(u64 *)mw->vbase; ^ drivers/ntb/test/ntb_perf.c:214:14: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast] dst_vaddr = (u64)(u64 *)dst; ^ This adds __iomem annotations where needed and changes the temporary variables to iomem pointers to avoid casting them to u64. I did not see the problem in linux-next earlier, but it show showed up in 4.5-rc1.
