Hi Roland! Richard et moi, we wondered what ELF_MACHINE_USER_ADDRESS_MASK »Mask identifying addresses reserved for the user program, where the dynamic linker should not map anything.«, the reason for it usage in sysdeps/mach/hurd/dl-sysdep.c:__mmap for vm_map's mask argument (but not in sysdeps/mach/hurd/mmap.c:__mmap which addmittedly is not »the dynamic linker«, so...), and then especially sysdeps/mach/hurd/dl-sysdep.c:fmh »XXX loser kludge for vm_map kernel bug« are all about. You added that in commit 5bf62f2d3a8af353fac661b224fc1604d4de51ea (well, waaaay before someone would speak about Git commits), and later touched it in commit 9ce8b3c817156108b9f1a1cf12a3fa6eb4332f11.
Grüße, Thomas
