Currently sci_dma_rx_push() has to find the active scatterlist itself,
but in some cases the caller already knows.
Hence let the caller pass the scatterlist, and introduce a helper to
find the active DMA request while we're at it.

During serial port shutdown, the DMA receive worker function may still
be called after the receive DMA cleanup function has been called.
Fix this race condition between work_fn_rx() and sci_rx_dma_release() by
acquiring the port's spinlock in sci_rx_dma_release().
This requires releasing the spinlock in work_fn_rx() before calling (any
function that may call) sci_rx_dma_release().
Terminate all active receive DMA descriptors to release them, and to
make sure no more completions come in.
Do the same in sci_tx_dma_release() for symmetry, although the serial
upper layer will no longer submit more data at this point of time.

64-bit on 64-bit. Hence "~BIT(...)" no longer fits in 32-bit, which
will cause future compiler warnings when assigning to 32-bit variables:
drivers/tty/serial/sh-sci.c: In function 'sci_init_single':

sci_port->error_clear = SCI_ERROR_CLEAR;
As these values are (at most) 32-bit register values anyway, cast them
to "u32" at the definition level to prevent such compiler warnings.

The #ifdef logic to clear SCxSR bits using RMW on SCIFA/SCIFB and SCIF
variants with some SCIFA features (sh7705/SH7720/sh7721) has several
drawbacks:
- It wasn't updated for newer R-Mobile variants (APE6),
- It doesn't correctly handle SoCs with both SCIF and SCIFA/B (e.g.
R-Car Gen2, but also legacy sh7723/sh7724),
- It doesn't play well with ARM multi-platform kernels: on R-Car Gen2,
SCIF/SCIFA/SCIFB/HSCIF were handled differently, depending on
whether r8a7740 or sh73a0 support was enabled or not,
Replace the #ifdef logic by runtime logic to fix this.
SCIFA/SCIFB and SCIF on sh7705/sh7720/sh7721 use RMW to clear error
bits, other variants use plain stores, as before.
Note that this changes behavior for SCIFA on sh7723/sh7724 (these SoCs
have both SCIF and SCIFA), which didn't use RMW before.

The following race conditions can happen when a serial port is used
as console.
Case1: CPU_B is used to detect an interrupt from a serial port,
but it can have interrupts disabled during the waiting time.
Case2: CPU_B clears UART_IER just after CPU_A sets UART_IER and then
a serial port may not make an interrupt.
Case3: CPU_A sets UART_IER just after CPU_B clears UART_IER.
This is an unexpected behavior for serial8250_console_write().
CPU_A [autoconfig_irq] | CPU_B [serial8250_console_write]
----------------------------|---------------------------------------
|
probe_irq_on() | spin_lock_irqsave(&port->lock,)
serial_outp(,UART_IER,0x0f) | serial_out(,UART_IER,0)
udelay(20); | uart_console_write()
probe_irq_off() |
| spin_unlock_irqrestore(&port->lock,)
Case1 and 2 can make autoconfig_irq() failed.
In these cases, the console doesn't work in interrupt mode and
"input overrun" (which can make operation mistakes) can happen
on some systems. Especially in the Case1, It is known that the
problem happens with high rate every boot once it occurs
because the boot sequence is always almost same.
port mutex makes sure that the autoconfig operation is exclusive of
any other concurrent HW access except by the console operation.
console lock is required in autoconfig_irq().

CIR type serial ports aren't real serial ports.
This is just a way to prevent legacy 8250 serial
driver from probing and eventually binding some
resources.
Since in current state such ports aren't providing
any real functionality and it is not possible
to change their type via setserial/ioctl(TIOCSSERIAL)
(due to UPF_FIXED_PORT flag set on them)
it is simpler and cleaner to not register them at all
with serial core.
Print a short message in this case so it is known
to user what has happened.
This way checks for PORT_8250_CIR in serial port
callbacks can be removed too, since they won't

Merge tag 'omap-for-v4.3/fixes-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
Fixes for omaps for v4.3-rc cycle:
- Two more patches to fix most of the MMC regressions with the
PBIAS regulator changes. At least two MMC driver related issues
still seems to remain for omap3 legacy booting and omap4 duovero.
Note that the dts changes depend on a recent regulator fix, and
are based on the regulator commit now in mainline kernel
- Enable autoidle for am43xx clocks to prevent clocks from staying
always on
- Fix i2c5 pinctrl offsets for omap5-uevm
- Enable PCA953X as that's needed for HDMI to work on omap5
- Update phy supplies for beagle x15 beta board
- Use palmas-usb for on beagle x15 to start using the related
driver that recently got merged

Pull crypto fixes from Herbert Xu:
"This fixes the following issues:
- check the return value of platform_get_irq as signed int in xgene.
- skip adf_dev_restore on virtual functions in qat.
- fix double-free with backlogged requests in marvell_cesa"

Pull SCSI target fixes from Nicholas Bellinger:
"This includes a iser-target series from Jenny + Sagi @ Mellanox that
addresses the few remaining active I/O shutdown bugs, along with a
patch to support zero-copy for immediate data payloads that gives a
nice performance improvement for small block WRITEs.
Also included are some recent >= v4.2 regression bug-fixes. The most
notable is a RCU conversion regression for SPC-3 PR registrations, and
recent removal of obsolete RFC-3720 markers that introduced a login
regression bug with MSFT iSCSI initiators.
Thanks to everyone who has been testing + reporting bugs for v4.x"
