Joseph Myers 61d8b5feee Share MAP_* flags between more architectures. ... Continuing bits/mman.h unification between architectures using the Linux kernel, this patch arranges for the common set of MAP_* flags to be used by two more architectures. That common set is moved to bits/mman-map-flags-generic.h, which is included by bits/mman.h, to allow architectures to use that common set even if they also have architecture-specific additions to it. As well as the generic bits/mman.h, the versions for x86 and ia64 are also then made to include bits/mman-map-flags-generic.h, so while they still need architecture-specific bits/mman.h (for MAP_32BIT and MAP_GROWSUP respectively), they do not need to duplicate the generic flag definitions in there. Tested for x86_64 and x86, and with build-many-glibcs.py. * sysdeps/unix/sysv/linux/bits/mman-map-flags-generic.h: New file. Most contents moved from .... * sysdeps/unix/sysv/linux/bits/mman.h: ... here. Move contents to and include <bits/mman-map-flags-generic.h>. * sysdeps/unix/sysv/linux/Makefile [$(subdir) = misc] (sysdep_headers): Add bits/mman-map-flags-generic.h. * sysdeps/unix/sysv/linux/ia64/bits/mman.h: Include <bits/mman-map-flags-generic.h>. [__USE_MISC] (MAP_GROWSUP): Only define this macro, not other macros defined in <bits/mman-map-flags-generic.h>. * sysdeps/unix/sysv/linux/x86/bits/mman.h: Include <bits/mman-map-flags-generic.h>. [__USE_MISC] (MAP_32BIT): Only define this macro, not other macros defined in <bits/mman-map-flags-generic.h>.		2018-09-26 12:33:14 +00:00
