I think you need a cast to either 'int' or 'long' here to make the corresponding format string work across all architectures. With the current version of your patch 2/2, it looks like it has to be %x for architectures with 64-bit phys_addr_t, but %lx for the other ones. Changing the 'u32 fault' variable to 'unsigned long' would also work here. Arnd

Fault is of type u32 and PAGE_MASK is type agnostic, hence the correct format for address should be %x not %lx otherwise: drivers/gpu/drm/i915/gt/intel_gt_print.h:29:36: error: format ‘%lx’ expects argument of type ‘long unsigned int’, but argument 6 has type ‘u32’ {aka ‘unsigned int’} [-Werror=format=] 29 | drm_dbg(&(_gt)->i915->drm, "GT%u: " _fmt, (_gt)->info.id, | ^~~~~~~~ include/drm/drm_print.h:424:39: note: in definition of macro ‘drm_dev_dbg’ 424 | __drm_dev_dbg(NULL, dev, cat, fmt, ##__VA_ARGS__) | ^~~ include/drm/drm_print.h:524:33: note: in expansion of macro ‘drm_dbg_driver’ 524 | #define drm_dbg(drm, fmt, ...) drm_dbg_driver(drm, fmt, ##__VA_ARGS__) | ^~~~~~~~~~~~~~ linux/drivers/gpu/drm/i915/gt/intel_gt_print.h:29:9: note: in expansion of macro ‘drm_dbg’ 29 | drm_dbg(&(_gt)->i915->drm, "GT%u: " _fmt, (_gt)->info.id, | ^~~~~~~ drivers/gpu/drm/i915/gt/intel_gt.c:310:25: note: in expansion of macro ‘gt_dbg’ 310 | gt_dbg(gt, "Unexpected fault\n" | ^~~~~~ Fix address format.
