Many bits/mman.h headers for Linux architectures have exactly the same contents, up to whitespace, comments and the number of leading 0s on constants. Specifically, this applies to architectures that, in the Linux kernel, either have no uapi/asm/mman.h, or have one that includes asm-generic/mman.h without any changes or additions relevant to glibc (this last case is the one that applies to Arm). It's not useful to have to duplicate the set of MAP_* constants in glibc for all such architectures and any new architectures with that property. Thus, this patch creates a generic sysdeps/unix/sysv/linux/bits/mman.h and removes all the architecture-specific versions that become unnecessary. Further unification remains possible after this patch. For example, the new bits/mman.h could become bits/mman-map-flags-generic.h so that it could also be used by architecture-specific bits/mman.h headers on architectures that use the generic flags but add architecture-specific ones to them. That would allow this common set of MAP_* definitions to be used on ia64 and x86 as well (architectures that include asm-generic/mman.h from their own uapi/asm/mman.h but define additional MAP_* values of their own). Tested with build-many-glibcs.py. * sysdeps/unix/sysv/linux/bits/mman.h: New file. * sysdeps/unix/sysv/linux/aarch64/bits/mman.h: Remove. * sysdeps/unix/sysv/linux/arm/bits/mman.h: Likewise. * sysdeps/unix/sysv/linux/m68k/bits/mman.h: Likewise. * sysdeps/unix/sysv/linux/microblaze/bits/mman.h: Likewise. * sysdeps/unix/sysv/linux/nios2/bits/mman.h: Likewise. * sysdeps/unix/sysv/linux/riscv/bits/mman.h: Likewise. * sysdeps/unix/sysv/linux/s390/bits/mman.h: Likewise. * sysdeps/unix/sysv/linux/sh/bits/mman.h: Likewise. |
