       "Here is the large set of TTY and Serial driver patches for 5.9-rc1.
      
        Lots of bugfixes in here, thanks to syzbot fuzzing for serial and vt
        and console code.
      
        Other highlights include:
      
         - much needed vt/vc code cleanup from Jiri Slaby
      
         - 8250 driver fixes and additions
      
         - various serial driver updates and feature enhancements
      
         - locking cleanup for serial/console initializations
      
         - other minor cleanups
      
        All of these have been in linux-next with no reported issues"

      Pull staging/IIO driver updates from Greg KH:
       "Here is the large set of Staging and IIO driver patches for 5.9-rc1.
      
        Lots of churn here, but overall the size increase in lines added is
        small, while adding a load of new IIO drivers.
      
        Major things in here:
      
         - lots and lots of IIO new drivers and frameworks added
      
         - IIO driver fixes and updates
      
         - lots of tiny coding style cleanups for staging drivers
      
         - vc04_services major reworks and cleanups
      
        We had 3 set of drivers move out of staging in this round as well:
      
         - wilc1000 wireless driver moved out of staging
      
         - speakup moved out of staging
      
         - most USB driver moved out of staging
      
        Full details are in the shortlog.
      
        All of these have been in linux-next with no reported issues. The last
        few changes here were to resolve reported linux-next issues, and they
        seem to have resolved the problems"

      This reverts commit 8bb9bf24.
      
      It seems the vmalloc page tables aren't always preallocated in all
      situations, because Jason Donenfeld reports an oops with this commit:
      
        BUG: unable to handle page fault for address: ffffe8ffffd00608
        #PF: supervisor read access in kernel mode
        #PF: error_code(0x0000) - not-present page

         ret_from_fork+0x1f/0x30
        CR2: ffffe8ffffd00608
      
      and that page fault address is right in that vmalloc space, and we
      clearly don't have a PGD/P4D entry for it.
      
      Looking at the "Code:" line, the actual fault seems to come from the
      'pwq->wq' dereference at the top of the process_one_work() function:
      
              struct pool_workqueue *pwq = get_work_pwq(work);
              struct worker_pool *pool = worker->pool;
              bool cpu_intensive = pwq->wq->flags & WQ_CPU_INTENSIVE;
      
      so 'struct pool_workqueue *pwq' is the allocation that hasn't been
      synchronized across CPUs.
      
      Just revert for now, while Joerg figures out the cause.

      Pull sched/fifo updates from Ingo Molnar:
       "This adds the sched_set_fifo*() encapsulation APIs to remove static
        priority level knowledge from non-scheduler code.
      
        The three APIs for non-scheduler code to set SCHED_FIFO are:
      
         - sched_set_fifo()
         - sched_set_fifo_low()
         - sched_set_normal()
      
        These are two FIFO priority levels: default (high), and a 'low'
        priority level, plus sched_set_normal() to set the policy back to
        non-SCHED_FIFO.
      
        Since the changes affect a lot of non-scheduler code, we kept this in
        a separate tree"
