The changes are: 1. Remove accept from auto-generation syscalls.list on the architecture that uses __NR_accept. 2. Define __NR_acccept 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.

The changes are: 1. Remove recv and recvfrom from auto-generation syscalls.list on the architecture that uses __NR_recv. 2. Define __NR_recv for such architectures. It was done instead of defining in default kernel-features.h because current Linux practice for new ports are to implement only __NR_recvfrom [1] and it will require adding new kernel-features for ports that do not require it (aarch64 for instance). 3. Define __NR_recvfrom as default (__ASSUME_RECVFROM_SYSCALL) and undef for architectures that do not support it. 4. Remove __ASSUME_RECVFROM_FOR_RECV_SYSCALL and decide to use __NR_recvfrom for recv generation based on __ASSUME_RECVFROM__SYSCALL.

The changes are: 1. Remove send and sendto from auto-generation syscalls.list on the architecture that uses __NR_send. 2. Define __NR_send for such architectures. It was done instead of defining in default kernel-features.h because current Linux practice for new ports are to implement only __NR_sendto [1] and it will require adding new kernel-features for ports that do not require it (aarch64 for instance). 3. Define __NR_sendto as default (__ASSUME_SENDTO_SYSCALL) and undef for architectures that do not support it. 4. Remove __ASSUME_SENDTO_FOR_SEND_SYSCALL and decide to use __NR_sendto for send generation based on __ASSUME_SENDTO_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/generic/send.c: Remove file. * sysdeps/unix/sysv/linux/x86_64/send.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/send.c: Likewise. * sysdeps/unix/sysv/linux/alpha/kernel-features.h (__ASSUME_SEND_SYSCALL): Define. * sysdeps/unix/sysv/linux/arm/kernel-features.h (__ASSUME_SEND_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/hppa/kernel-features.h (__ASSUME_SEND_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/ia64/kernel-features.h (__ASSUME_SEND_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/microblaze/kernel-features.h (__ASSUME_SEND_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/mips/kernel-features.h [_MIPS_SIM == _ABIO32] (__ASSUME_SEND_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/sh/kernel-features.h (__ASSUME_SEND_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/i386/kernel-features.h (__ASSUME_SENDTO_FOR_SEND_SYSCALL): Remove.
