        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

       "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.

      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

         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"

      net: thunderx: initialize VF's mailbox mutex before first usage · c1055b76

      A VF's mailbox mutex is not getting initialized by nicvf_probe() until after
      it is first used. And such usage is resulting in...

      This problem is resolved by moving the call to mutex_init() up earlier
      in nicvf_probe().

      ====================
      misc bug fixes for the hso driver
      
      1. Code reuse led to an unregistration of a net driver that has not been
      registered
      2. The kernel complains generically if kmalloc with GFP_KERNEL fails
      3. A race that can lead to an URB that is in use being reused or
      a use after free

      usb: hso: remove bogus check for EINPROGRESS · abaf00ff
      Oliver Neukum authored
      This check an inherent race. It opens a race where
      an error code has already been set or cleared yet
      the URB has not been given back. We cannot do
      such an optimization and must unlink unconditionally.
