      Pull io_uring fixes from Jens Axboe:
       "A few differerent things in here.
      
        Seems like syzbot got some more io_uring bits wired up, and we got a
        handful of reports and the associated fixes are in here.
      
        General fixes too, and a lot of them marked for stable.
      
        Lastly, a bit of fallout from the async buffered reads, where we now
        more easily trigger short reads. Some applications don't really like
        that, so the io_read() code now handles short reads internally, and
        got a cleanup along the way so that it's now easier to read (and
        documented). We're now passing tests that failed before"

      parisc: fix PMD pages allocation by restoring pmd_alloc_one() · 6f6aea7e
      Mike Rapoport authored
      Commit 1355c31e ("asm-generic: pgalloc: provide generic pmd_alloc_one()
      and pmd_free_one()") converted parisc to use generic version of
      pmd_alloc_one() but it missed the fact that parisc uses order-1 pages for
      PMD.
      
      Restore the original version of pmd_alloc_one() for parisc, just use
      GFP_PGTABLE_KERNEL that implies __GFP_ZERO instead of GFP_KERNEL and
      memset.
      
      Fixes: 1355c31e ("asm-generic: pgalloc: provide generic pmd_alloc_one() and pmd_free_one()")
