Changes

* Integer overflows for srcaddr+size and dstaddr+size are now checked(with [[6.0.0-11]]), which were not checked before.

* Integer overflows for srcaddr+size and dstaddr+size are now checked(with [[6.0.0-11]]), which were not checked before.

* The kernel now also checks whether the srcaddr/dstaddr(+size) is within userland memory(0x20000000), the kernel now(with [[6.0.0-11]]) returns an error when the address is beyond userland memory. Using an address >=0x20000000 would only result in the kernel reading from the process L1 MMU table, beyond the memory allocated for that MMU table(for vaddr->physaddr conversion), therefore this issue likely(?) wasn't useful.
