mm: untag user pointers in mmap/munmap/mremap/brk
There isn't a good reason to differentiate between the user address space
layout modification syscalls and the other memory permission/attributes
ones (e.g. mprotect, madvise) w.r.t. the tagged address ABI. Untag the
user addresses on entry to these functions.
