2015-03-04xtensa: provide __NR_sync_file_range2 instead of __NR_sync_file_rangeMax Filippov
xtensa actually uses sync_file_range2 implementation, so it should define __NR_sync_file_range2 as other architectures that use that function. That fixes userspace interface (that apparently never worked) and avoids special-casing xtensa in libc implementations. See the thread ending at http://lists.busybox.net/pipermail/uclibc/2015-February/048833.html for more details. Cc: stable@vger.kernel.org Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>

2014-10-21xtensa: re-wire umount syscall to sys_oldumountMax Filippov
Userspace actually passes single parameter (path name) to the umount syscall, so new umount just fails. Fix it by requesting old umount syscall implementation and re-wiring umount to it. Cc: stable@vger.kernel.org Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>

2012-10-25xtensa: allow multi-inclusion for uapi/unistd.hChris Zankel
Xtensa implements a method that allows to generate a arbitrary output for each system call by defining the __SYSCALL(number, function, num_args). This usually requires to include uapi/unistd.h twice. Instead of removing the guard agains multiple inclusion entirely, allow to include unistd.h again only if __SYSCALL is defined. Note that __SYSCALL gets always undefined at the end of the file.

Add the following system calls to the syscall table: fallocate sendmmsg umount2 syncfs epoll_create1 inotify_init1 signalfd4 dup3 pipe2 timerfd_create timerfd_settime timerfd_gettime eventfd2 preadv pwritev fanotify_init fanotify_mark process_vm_readv process_vm_writev name_to_handle_at open_by_handle_at sync_file_range perf_event_open rt_tgsigqueueinfo clock_adjtime prlimit64 kcmp Note that we have to use the 'sys_sync_file_range2' version, so that the 64-bit arguments are aligned correctly to the argument registers.
