    Merge tag 'asm-generic-4.6' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic
    
    Pull asm-generic update from Arnd Bergmann:
     "Here is one patch to wire up the preadv/pwritev system calls in the
      generic system call table, which is required for all architectures
      that were merged in the last few years, including arm64.
    
      Usually these get merged along with the syscall implementation or one
      of the architecture trees, but this time that did not happen.
    
      Andre and Christoph both sent a version of this patch, I picked the
      one I got first"
