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. 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/alpha/kernel-features.h (__ASSUME_RECV_SYSCALL): Define. * sysdeps/unix/sysv/linux/arm/kernel-features.h (__ASSUME_RECV_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/hppa/kernel-features.h (__ASSUME_RECV_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/ia64/kernel-features.h (__ASSUME_RECV_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/mips/kernel-features.h [_MIPS_SIM == _ABIO32] (__ASSUME_RECV_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/i386/kernel-features.h (__ASSUME_RECVFROM_SYSCALL): Define whether the kernel supports it.
