This patch adds a bunch of missing syscalls to AVR32: __NR_pread64 __NR_pwrite64 __NR_timerfd_create __NR_fallocate __NR_timerfd_settime __NR_timerfd_gettime __NR_signalfd4 __NR_eventfd2 __NR_epoll_create1 __NR_dup3 __NR_pipe2 __NR_inotify_init1 __NR_preadv __NR_pwritev __NR_rt_tgsigqueueinfo __NR_perf_event_open __NR_recvmmsg __NR_fanotify_init __NR_fanotify_mark __NR_prlimit64 __NR_name_to_handle_at __NR_open_by_handle_at __NR_clock_adjtime __NR_syncfs __NR_sendmmsg __NR_process_vm_readv __NR_process_vm_writev __NR_kcmp __NR_finit_module __NR_sched_setattr __NR_sched_getattr __NR_renameat2 __NR_seccomp __NR_getrandom __NR_memfd_create __NR_bpf __NR_execveat On AVR32, all parameters beyond the 5th are passed on the stack. System calls don't use the stack -- they borrow a callee-saved register instead. This means that syscalls that take 6 parameters must be called through a stub that pushes the last parameter on the stack. This relates to syscall fallocate, fanotify_mark, process_vm_readv, and process_vm_writev. Signed-off-by: Hans-Christian Egtvedt <egtvedt@samfundet.no>
