Joseph Myers 1283c478aa Fix Arm __ASSUME_COPY_FILE_RANGE (bug 23915). ... The generic kernel-features.h defines __ASSUME_COPY_FILE_RANGE for 4.5 and later kernels. However, for 32-bit Arm binaries running on 64-bit Arm kernels, the syscall was only wired up in the 4.7 kernel, although the 32-bit Arm kernel had the syscall from 4.5 onwards. This patch corrects the Arm kernel-features.h to undefine the macro for configured minimum kernel versions before 4.7. Tested (compilation only) with a build-many-glibcs.py build for arm-linux-gnueabi. [BZ #23915] * sysdeps/unix/sysv/linux/arm/kernel-features.h [__LINUX_KERNEL_VERSION < 0x040700] (__ASSUME_COPY_FILE_RANGE): Undefine.		2018-11-23 17:53:50 +00:00
