From d0e91e8c4ef77997c940538eaa752799c9dda2d3 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Mon, 1 Oct 2018 20:30:57 +0000 Subject: Move MREMAP_* to bits/mman-shared.h. The MREMAP_* flags are identical between bits/mman-linux.h and the hppa bits/mman.h; thus, they should be in bits/mman-shared.h instead to avoid unnecessary duplication. This patch moves them there. Tested for x86_64, and with build-many-glibcs.py. * sysdeps/unix/sysv/linux/bits/mman-linux.h [__USE_GNU] (MREMAP_MAYMOVE): Do not define here. [__USE_GNU] (MREMAP_FIXED): Likewise. * sysdeps/unix/sysv/linux/bits/mman-shared.h [__USE_GNU] (MREMAP_MAYMOVE): Define here instead. [__USE_GNU] (MREMAP_FIXED): Likewise. * sysdeps/unix/sysv/linux/hppa/bits/mman.h [__USE_GNU] (MREMAP_MAYMOVE): Remove.
