Add MAP_FIXED_NOREPLACE from Linux 4.17 to bits/mman.h.
Linux 4.17 adds MAP_FIXED_NOREPLACE (value 0x100000 on most architectures, 0x200000 on alpha). This patch adds that macro to glibc's bits/mman.h headers. Tested for x86_64. * sysdeps/unix/sysv/linux/aarch64/bits/mman.h [__USE_MISC] (MAP_FIXED_NOREPLACE): New macro. * sysdeps/unix/sysv/linux/alpha/bits/mman.h [__USE_MISC] (MAP_FIXED_NOREPLACE): Likewise. * sysdeps/unix/sysv/linux/arm/bits/mman.h [__USE_MISC] (MAP_FIXED_NOREPLACE): Likewise. * sysdeps/unix/sysv/linux/hppa/bits/mman.h [__USE_MISC] (MAP_FIXED_NOREPLACE): Likewise. * sysdeps/unix/sysv/linux/ia64/bits/mman.h [__USE_MISC] (MAP_FIXED_NOREPLACE): Likewise. * sysdeps/unix/sysv/linux/m68k/bits/mman.h [__USE_MISC] (MAP_FIXED_NOREPLACE): Likewise. * sysdeps/unix/sysv/linux/microblaze/bits/mman.h [__USE_MISC] (MAP_FIXED_NOREPLACE): Likewise. * sysdeps/unix/sysv/linux/mips/bits/mman.h [__USE_MISC] (MAP_FIXED_NOREPLACE): Likewise. * sysdeps/unix/sysv/linux/nios2/bits/mman.h [__USE_MISC] (MAP_FIXED_NOREPLACE): Likewise. * sysdeps/unix/sysv/linux/powerpc/bits/mman.h [__USE_MISC] (MAP_FIXED_NOREPLACE): Likewise. * sysdeps/unix/sysv/linux/riscv/bits/mman.h [__USE_MISC] (MAP_FIXED_NOREPLACE): Likewise. * sysdeps/unix/sysv/linux/s390/bits/mman.h [__USE_MISC] (MAP_FIXED_NOREPLACE): Likewise. * sysdeps/unix/sysv/linux/sh/bits/mman.h [__USE_MISC] (MAP_FIXED_NOREPLACE): Likewise. * sysdeps/unix/sysv/linux/sparc/bits/mman.h [__USE_MISC] (MAP_FIXED_NOREPLACE): Likewise. * sysdeps/unix/sysv/linux/x86/bits/mman.h [__USE_MISC] (MAP_FIXED_NOREPLACE): Likewise.
