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. Signed-off-by:

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. Signed-off-by:

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 Signed-off-by:

For Synopsys DesignWare 8250 uart which version >= 4.00a, there's a valid divisor latch fraction register. The fractional divisor width is 4bits ~ 6bits. Now the preparation is done, it's easy to add the feature support. This patch firstly tries to get the fractional divisor width during probe, then setups dw specific get_divisor() and set_divisor() hook. Signed-off-by:

As of commit b36f09c3 ("dmaengine: Add transfer termination synchronization support"), dmaengine_terminate_all() is deprecated. 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. Replace calls to dmaengine_terminate_all() in DMA failure paths by calls to dmaengine_terminate_async(), as these are usually done in atomic context. Signed-off-by:

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. Signed-off-by:

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" * tag 'selinux-pr-20180629' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux: selinux: move user accesses in selinuxfs out of locked regions

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)" * tag 'for-linus-20180629' of git://git.kernel.dk/linux-block: sg: remove ->sg_magic member drbd: Fix drbd_request_prepare() discard handling blk-mq: don't queue more if we get a busy return block: Fix cloning of requests with a special payload nvme-rdma: fix possible double free of controller async event buffer block: Fix transfer when chunk sectors exceeds max
