printk supports using %pa for phys_addr_t and %zx for size_t so use those instead of %lx and casts to unsigned long.
Other miscellaneous changes around this: Always use 0x%zx for size instead of one use of decimal. Coalesce format and align arguments.

Sounds good to me, except using %pa instead is better still. drivers/iommu/iommu.c | 23 ++++++++++------------- 1 file changed, 10 insertions(+), 13 deletions(-) diff --git a/drivers/iommu/iommu.c b/drivers/iommu/iommu.c index ab1fa19..fbe9ca7 100644 --- a/drivers/iommu/iommu.c +++ b/drivers/iommu/iommu.c @@ -807,20 +807,18 @@ int iommu_map(struct iommu_domain *domain, unsigned long iova, * size of the smallest page supported by the hardware */ if (!IS_ALIGNED(iova | paddr | size, min_pagesz)) { - pr_err("unaligned: iova 0x%lx pa 0x%lx size 0x%lx min_pagesz " - "0x%x\n", iova, (unsigned long)paddr, - (unsigned long)size, min_pagesz); + pr_err("unaligned: iova 0x%lx pa 0x%pa size 0x%zx min_pagesz 0x%x\n", + iova, &paddr, size, min_pagesz); return -EINVAL; } - pr_debug("map: iova 0x%lx pa 0x%lx size 0x%lx\n", iova, - (unsigned long)paddr, (unsigned long)size); + pr_debug("map: iova 0x%lx pa 0x%pa size 0x%zx\n", iova, &paddr, size); while (size) { size_t pgsize = iommu_pgsize(domain, iova | paddr, size); - pr_debug("mapping: iova 0x%lx pa 0x%lx pgsize %lu\n", iova, - (unsigned long)paddr, (unsigned long)pgsize); + pr_debug("mapping: iova 0x%lx pa 0x%pa pgsize 0x%zx\n", + iova, &paddr, pgsize); ret = domain->ops->map(domain, iova, paddr, pgsize, prot); if (ret) @@ -857,13 +855,12 @@ size_t iommu_unmap(struct iommu_domain *domain, unsigned long iova, size_t size) * by the hardware */ if (!IS_ALIGNED(iova | size, min_pagesz)) { - pr_err("unaligned: iova 0x%lx size 0x%lx min_pagesz 0x%x\n", - iova, (unsigned long)size, min_pagesz); + pr_err("unaligned: iova 0x%lx size 0x%zx min_pagesz 0x%x\n", + iova, size, min_pagesz); return -EINVAL; } - pr_debug("unmap this: iova 0x%lx size 0x%lx\n", iova, - (unsigned long)size); + pr_debug("unmap this: iova 0x%lx size 0x%zx\n", iova, size); /* * Keep iterating until we either unmap 'size' bytes (or more) @@ -876,8 +873,8 @@ size_t iommu_unmap(struct iommu_domain *domain, unsigned long iova, size_t size) if (!unmapped_page) break; - pr_debug("unmapped: iova 0x%lx size %lx\n", iova, - (unsigned long)unmapped_page); + pr_debug("unmapped: iova 0x%lx size 0x%zx\n", + iova, unmapped_page); iova += unmapped_page; unmapped += unmapped_page; -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
