From 32977242f80e343e2247f77e53fe20e8f7c23938 Mon Sep 17 00:00:00 2001 From: Marek Szyprowski Date: Thu, 23 Jun 2022 11:36:29 +0200 Subject: iommu/exynos: Make driver independent of the system page size PAGE_{SIZE,SHIFT} macros depend on the configured kernel's page size, but the driver expects values calculated as for 4KB pages. Fix this.
