The syscall pipe2 was added in linux 2.6.27 and glibc requires linux 3.2.0. The patch removes the arch-specific implementation for alpha, ia64, mips, sh, and sparc which requires a different kernel ABI than the usual one. Checked on x86_64-linux-gnu and with a build for the affected ABIs. |

This hierarchy supports Linux systems using the new asm-generic/unistd.h, which removes many familiar old syscalls. For example, to implement open(), newer Linux architectures require glibc to invoke the __NR_openat syscall with AT_FDCWD. This hierarchy provides all those implementations. It also provides support for 32-bit platforms using the 64-bit kernel syscall APIs, as the 32-bit ones are no longer provided. Note that newer ILP32 environments (x32 or AArch64:ILP32, for example) are converting to use more 64-bit types in kernel syscalls, so that aspect of this support is in more flux as of this writing.
