Yes, I've just checked, starting at 64K...

No. I've changed in load_aout_binary() set_personality(PER_LINUX) to set_personality(PER_LINUX_32BIT), and now I have another error. You will laugh, but...
$ netscape 665:/usr/lib/netscape/netscape-communicator: : Fatal Error: mmap available address is not larger than requested
This happens after mmap(0x7fdc8000, 40960, PROT_READ|PROT_WRITE|PROT_EXEC, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x40018000
And note, this is the message from loader, not from netscape itself. So I think my second patch is an easiest solution for now. Look, compared with the code in Linus' tree: - it doesn't add any overhead in general case (addr == 0); - if the specified address is too high and we can't find a free area above it, we just continue search from TASK_UNMAPPED_BASE as usual; - if address is too low, extra cost is only compare and taken branch. I think it's clean enough.
