There are functions tlb_fill(), cpu_unaligned_access() and do_unaligned_access() that are called with access type and mmu index arguments. But these arguments are named 'is_write' and 'is_user' in their declarations. The patches fix the arguments to avoid a confusion. Backports commit b35399bb4e9968296a12303b00f9f2066470e987 from qemu
