From: Mika Kuoppala Date: Thu, 25 Jun 2015 15:35:05 +0000 (+0300) Subject: drm/i915/gtt: Allow >= 4GB sizes for vm. X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c44ef60e437019b8ca1dab8b4d2e8761fd4ce1e9;p=linux-beck.git drm/i915/gtt: Allow >= 4GB sizes for vm. We can have exactly 4GB sized ppgtt with 32bit system. size_t is inadequate for this. v2: Convert a lot more places (Daniel) Signed-off-by: Mika Kuoppala Reviewed-by: Michel Thierry Signed-off-by: Daniel Vetter --- diff --git a/drivers/char/agp/intel-gtt.c b/drivers/char/agp/intel-gtt.c index 0b4188b9af7c..4734d02ca899 100644 --- a/drivers/char/agp/intel-gtt.c +++ b/drivers/char/agp/intel-gtt.c @@ -1408,8 +1408,8 @@ int intel_gmch_probe(struct pci_dev *bridge_pdev, struct pci_dev *gpu_pdev, } EXPORT_SYMBOL(intel_gmch_probe);
