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>.
