I find it makes it harder to follow code flow when __weak functions are involved. Ifdefs are ugly, no question, but they're easier to grep for, see when they'll be defined and know which of the arch_pick_mmap_layout() functions will be called. __weak certainly has its uses (eg the sys_ni_syscall is great) but I find it's becoming overused. My basic point here is that __weak makes the code easier to write but harder to read, and we're supposed to be optimising for easier to read. -- Intel are signing my paycheques ... these opinions are still mine "Bill, look, we understand that you're interested in selling us this operating system, but compare it to ours.
