[PATCH 2/8] linux-user: Sink call to do_safe_futex

Leave only the argument adjustments within the shift, and sink the actual syscall to the end. Sink the timespec conversion as well, as there will be more users. Signed-off-by: Richard Henderson --- linux-user/syscall.c | 60 +++- 1 file changed, 31 insert
