Add support for a "RZ_SCIFA" which is different than a traditional
SCIFA. It looks like a normal SCIF with FIFO data, but with a
compressed address space. Also, the break out of interrupts
are different then traditinal SCIF: ERI/BRI, RXI, TXI, TEI, DRI.
The R7S9210 (RZ/A2) contains this type of SCIF.

In order to open up the required power gate before any operation can be
effectively performed over the serial bus between CPU and serdev, it's
clearly essential to add common attach functions for PM domains to serdev
at the probe phase.

Similarly, the relevant dettach function for the PM domains should be
properly and reversely added at the remove phase.

for our build, this is crashing at:

    circ->buf[circ->head] = c;

Looking in uart_port_startup(), it seems that circ->buf (state->xmit.buf)
protected by the "per-port mutex", which based on uart_port_check() is
state->port.mutex. Indeed, the lock acquired in uart_put_char() is
uport->lock, i.e. not the same lock.

Anyway, since the lock is not acquired, if uart_shutdown() is called, the
last chunk of that function may release state->xmit.buf before its assigned
to null, and cause the race above.

To fix it, let's lock uport->lock when allocating/deallocating
state->xmit.buf in addition to the per-port mutex.

v2: switch to locking uport->lock on allocation/deallocation instead of
    locking the per-port mutex in uart_put_char. Note that since
    uport->lock is a spin lock, we have to switch the allocation to
    GFP_ATOMIC.
v3: move the allocation outside the lock, so we can switch back to
    GFP_KERNEL

Replace calls to dmaengine_terminate_all() in DMA release code by calls
to dmaengine_terminate_sync(), as the latter waits until all running
completion callbacks have finished.

The transmit DMA workqueue is never stopped, hence the work function may

Fix this race condition by cancelling queued work, if any, before DMA

When the sh-sci driver detects an issue with DMA during operation, it
falls backs to PIO, and releases all DMA resources.

As releasing DMA resources immediately has no advantages, but
complicates the code, and is susceptible to races, it is better to
postpone this to port shutdown.

This allows to remove the locking from sci_rx_dma_release() and
sci_tx_dma_release(), but requires keeping a copy of the DMA channel
pointers for release during port shutdown.

Pull selinux fix from Paul Moore:
 "One fairly straightforward patch to fix a longstanding issue where a
  process could stall while accessing files in selinuxfs and block
  everyone else due to a held mutex.

  The patch passes all our tests and looks to apply cleanly to your
  current tree"

Pull block fixes from Jens Axboe:
 "Small set of fixes for this series. Mostly just minor fixes, the only
  oddball in here is the sg change.

  The sg change came out of the stall fix for NVMe, where we added a
  mempool and limited us to a single page allocation. CONFIG_SG_DEBUG
  sort-of ruins that, since we'd need to account for that. That's
  actually a generic problem, since lots of drivers need to allocate SG
  lists. So this just removes support for CONFIG_SG_DEBUG, which I added
  back in 2007 and to my knowledge it was never useful.

  Anyway, outside of that, this pull contains:

   - clone of request with special payload fix (Bart)

   - drbd discard handling fix (Bart)

   - SATA blk-mq stall fix (me)

   - chunk size fix (Keith)

   - double free nvme rdma fix (Sagi)"

 "Two regression fixes, and a new syscall wire-up:

   - A fix for the recent conversion to time64_t in the powermac RTC

   - Wire up the new io_pgetevents() syscall.
