commit cad20f3e7d42e6371896e2492f0fc3a081314238
Author: Mark Wielaard <m...@klomp.org>

Support mmap MAP_FIXED_NOREPLACE if defined
Define VKI_MAP_FIXED_NOREPLACE for amd64-linux, arm-linux,
arm64-linux, mips32-linux, mips64-linux, riscv64-linux and x86-linux.
If it is defined then ML_(generic_PRE_sys_mmap) will also interpret
VKI_MAP_FIXED_NOREPLACE as an MFixed hint. If the aspace manager
doesn't find a MAP_FIXED_NOREPLACE ok, then fail with EEXIST. If the
actual kernel mmap request fails and MAP_FIXED_NOREPLACE is set also
immediately fail with EEXIST without retrying.
This fixes the LTP mmap17 testcase.
