I took a look at the code again and I dont really understand how the particular case when we get a high address from the kernel while mmap_min_addr is busy case is supposed to work :/ In fact, for CRIS it never works on my host. I get a high address that doesnt fit, then the code tries to go back to mmap_min_addr but if that was busy my kernel just returns the same addr we got the first try and mmap_find_vma gives -1 due to repeat. I changed it locally to keep scanning after a wrap until we succeed to allocate a chunk or rewrap (SLOW) but at least I can run dynamically linked CRIS programs again. Cheers
