    avr32: wire up missing syscalls · f3240c1f
    Hans-Christian Egtvedt authored
    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.
