--- Comment #3 from Jan Palus <jpalus at fastmail dot com> ---
Address for mmap is defined as "l->l_addr + c->mapstart" where l->l_addr=3D=
=3D0 and
c->mapstart=3D=3D0x10000. As far as I can tell the latter comes from ELF so=
 either
5.17 loads binary in wrong place or l->l_addr should be adjusted accordingl=
y.
In this code path nothing seems to set l->l_addr to anything but 0 though
admittedly this is all way over my head.
