From: Adhemerval Zanella <adhemerval.zanella@linaro.org> This patch consolidates the accept Linux syscall implementation on sysdeps/unix/sysv/linux/accept.c. The changes are: 1. Remove accept from auto-generation syscalls.list on the architecture that uses __NR_accept. 2. Define __NR_accept as default (__ASSUME_ACCEPT_SYSCALL) and undef for architectures that do not support it. 3. Remove __ASSUME_ACCEPT4_FOR_ACCEPT_SYSCALL and decide to use __NR_accept4 for accept generation based on __ASSUME_ACCEPT4_SYSCALL. Checked on i686-linux-gnu, x86_64-linux-gnu, x86_64-linux-gnux32, aarch64-linux-gnu, arm-linux-gnueabihf, and powerpc64le-linux-gnu. * sysdeps/unix/sysv/linux/accept.c (__libc_accept): Replace __ASSUME_ACCEPT4_FOR_ACCEPT_SYSCALL by __ASSUME_ACCEPT4_SYSCALL. * sysdeps/unix/sysv/linux/alpha/syscalls.list: Remove accept from auto-generation list. * sysdeps/unix/sysv/linux/arm/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/generic/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/hppa/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/ia64/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/mips/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/x86_64/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/i386/kernel-features.h (__ASSUME_ACCEPT4_FOR_ACCEPT_SYSCALL): Remove define.
