    arm64: Implement __lshrti3 library function · 9bfe7553

     ("arm64: support __int128 on gcc 5+") added support
    for the __int128 data type, but this breaks the build in some configurations
    where GCC ends up emitting calls to the __lshrti3 helper in libgcc, which
    results in a link error:
      kernel/sched/fair.o: In function `__calc_delta':
      fair.c:(.text+0xca0): undefined reference to `__lshrti3'
      kernel/time/timekeeping.o: In function `timekeeping_resume':
      timekeeping.c:(.text+0x3f60): undefined reference to `__lshrti3'
      make: *** [vmlinux] Error 1
    Fix the build by providing an implementation of __lshrti3, like we do
    already for __ashlti3 and __ashrti3.
