6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Guo Ren <guoren@xxxxxxxxxxxxxxxxx>
[ Upstream commit 10c62c38b073ecea775b7e23fa7c7a3995a84ff3 ]
When __BITS_PER_LONG == 32, size_t is defined as unsigned int rather
than unsigned long. Therefore, we should use size_t to avoid
type-checking errors.
Fixes: 488ffbf18171 ("iommu/riscv: Paging domain support")
