Subject: [PATCH 1/3] iommu: omap: Fix pointer cast -Wpointer-to-int-cast warnings on 64 bit
pointers should be casted to unsigned long to avoid
-Wpointer-to-int-cast warnings when compiling on 64-bit platform (e.g.
with COMPILE_TEST):
drivers/iommu/omap-iommu.c: In function ‘omap2_iommu_enable’:
drivers/iommu/omap-iommu.c:170:25: warning:
cast from pointer to integer of different size [-Wpointer-to-int-cast]
if (!obj->iopgd || !IS_ALIGNED((u32)obj->iopgd, SZ_16K))
