Hi Marek,

Can you run some graphics benchmark program to check the performance
between
1.

git://git.kernel.org/pub/scm/linux/kernel/git/yinghai/linux-yinghai.git
  branch: for-pci-allocate-fit-3.18

2.
v 3.18 + clear mmio64 flags when children device does not support it

Thanks

Yinghai

I have run Unigine Heaven benchmark on both versions (I tried version 2. with and also without kernel parameters "debug ignore_loglevel pci=realloc") and the performance of each version was the same (70-71 points). I tried to run this benchmark also with kernel 3.15.10 and the result was 67 points. Tomorrow I can try to run some more benchmarks, today I didn't have much time.
