all: Use macros for printf/scanf format specifiers
Any types that are fixed width should use the standard format specifier macros (PRI... for printf-type functions, SCN... for scanf-type functions) to ensure proper data access. Prior to this ifpps was crashing in 32-bit environments due to the following call mvwprintw(screen, (*voff)++, 2, "%s,%s %s (%s%s), t=%lums, cpus=%u%s/%u" " ", uts.release, machine, ifname, drvinf.driver, buff, ms_interval, top_cpus, top_cpus > 0 && top_cpus < cpus ? "+1" : "", cpus); since ms_interval is a uint64_t but %lu expects an unsigned long, which is only 32 bits.

Other callers of i915_gem_object_to_ggtt() seem to also check for the returned pointer being NULL and warn about it, so this clearly has happened before in other places. [ Reported it originally to the i915 developers on Jan 8, applying the ugly workaround on my own now after triggering the problem for the second time with no feedback. This is likely to be the same bug reported as https://bugs.freedesktop.org/show_bug.cgi?id=98829 https://bugs.freedesktop.org/show_bug.cgi?id=99134 which has a patch for the underlying problem, but it hasn't gotten to me, so I'm applying the workaround. ] Cc: Daniel Vetter <daniel.vetter@intel.com> Cc: Jani Nikula <jani.nikula@linux.intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Cc: Imre Deak <imre.deak@intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
