From: Joerg Roedel <jroe...@suse.de>
The value -ENOMEM is the expected return code for mmap when
the address range verification failes on a MAP_FIXED
request, as stated in the specification:
[ENOMEM]
MAP_FIXED was specified, and the range
[addr,addr+len) exceeds that allowed for the
address space of a process;
The ia64_mmap_check() function is part of that verification
and should return -ENOMEM too.
