Use imx_start_tx() just to enable the TX interrupt. It's the job of the
TX interrupt ISR to fill the transmit buffer, then. If the transmit buffer
is empty, the TX interrupt should be executed as soon as the start_tx()
enables the interrupt, so there is no reason for the extra
imx_transmit_buffer() call, here. Remove it.

This patch fixes many bugs in the code dealing with the hardware handshake.
As an example, in atmel_set_termios(), we used to test whether the CRTSCTS
c_cflag was set. If so, we selected the "Hardware Handshake" mode through the
Mode Register. However, few lines below the mode was reset to "Normal" (0).
So there was no way to select the "Hardware Handshake" mode. To fix this issue,
we moved the CRTSCRTS c_cflag test AFTER the mode has been reset to "Normal".
Also setting the RTSEN and RTSDIS bits in the Control Register has different
results whether the USART is set in "Normal" or "Hardware Handshake" mode:
1) "Normal" mode
- the RTSEN bit forces the RTS line to low level, which tells the remote peer
that we are ready to received new data.
- the RTSDIS bit forces the RTS line to high level, which tells the remote peer
to stop sending new data.
2) "Hardware Handshake" mode
- the RTSEN bit forces the RTS line to high level.
- the RTSDIS bit lets the hardware control the RTS line.
WARNING:
when FIFOs are not available or not enabled, the RTS line is controlled by the
PDC. This is why using the Hardware Handshake mode requires using the PDC
channel for reception. However the Hardware Handshake mode DOES NOT work with
DMA controller since it cannot control the RTS line.
Future designs with FIFOs will introduce a new feature: the RTS line will be
controlled by the RX FIFO using thresholds. This patch was tested with this new
design.

-EDEFER error wasn't handle properly by atmel_serial_probe().
As an example, when atmel_serial_probe() is called for the first time, we pass
the test_and_set_bit() test to check whether the port has already been
initalized. Then we call atmel_init_port(), which may return -EDEFER, possibly
returned before by clk_get(). Consequently atmel_serial_probe() used to return
this error code WITHOUT clearing the port bit in the "atmel_ports_in_use" mask.
When atmel_serial_probe() was called for the second time, it used to fail on
the test_and_set_bit() function then returning -EBUSY.
When atmel_serial_probe() fails, this patch make it clear the port bit in the
"atmel_ports_in_use" mask, if needed, before returning the error code.

atmel_serial_probe() calls atmel_init_port(). In turn, atmel_init_port() calls
clk_disable_unprepare() to disable the peripheral clock before returning.
Later atmel_serial_probe() accesses some I/O registers such as the Mode and
Control registers for RS485 support then the Name and Version registers, through a call to
atmel_get_ip_name(), but at that moment the peripheral clock was still
disabled.

Because the OMAP3 UART ignores MCR[1] (RTS) in autoRTS mode, autoRTS
mode must not be enabled unless RTS is set (or port->mctrl & TIOCM_RTS,
which is equivalent).
Fixes premature raising of RTS in omap_8250_set_termios() -- RTS was
raised even before UART mode was selected.
Fixes raise of RTS after port has been shutdown; omap_8250_pm() re-enabled
RTS after omap_8250_shutdown().

The OMAP3 UART ignores MCR[1] (ie., UART_MCR_RTS) when in autoRTS
mode (UPF_HARD_FLOW + CRTSCTS). This makes it impossible for either
the serial core or userspace to manually flow control the sender.
Disable autoRTS mode when RTS is lowered and restore the previous
mode when RTS is raised.
Note that the OMAP3 UART provides no mechanism for switching from
autoRTS mode without corrupting incoming data; to access the
necessary register, the line control settings must be set to 8-e-2
and thus any data received during that time will be interpreted with
those settings. This corruption has been observed in practice.

drm/tegra: Fixes for v3.19-rc1
This is a set of fixes for two regressions and one bug in the IOMMU
mapping code. It turns out that all of these issues turn up primarily
on Tegra30 hardware. The IOMMU mapping bug only manifests on buffers
that aren't multiples of the page size. I happened to be testing HDMI
with 1080p while writing the code and framebuffers for that happen to
fit exactly within 2025 pages of 4 KiB each.
One of the regressions is caused by the IOMMU code allocating pages from
shmem which can have associated cache lines. If the pages aren't flushed
then these cache lines may be flushed later on and cause framebuffer
corruption. I'm not sure why I didn't see this before. Perhaps the board
that I was using had enough RAM so that the pages shmem would hand out
had a better chance of being unused. Or maybe I didn't look too closely.
The fix for this is to fake up an SG table so that it can be passed to
the DMA API. Ideally this would use drm_clflush_*(), but implementing
that for ARM causes DRM to fail to build as a module since some of the
low-level cache maintenance functions aren't exported. Hopefully we can
get a suitable API exported on ARM for the next release.
The second regression is caused by a mismatch between the hardware pipe
number and the CRTC's DRM index. These were used inconsistently, which
could cause one code location to call drm_vblank_get() with a different
pipe than the corresponding drm_vblank_put(), thereby causing the
reference count to become unbalanced. Alexandre also reported a possible
race condition related to this, which this series also fixes.

Pull CONFIG_PM_RUNTIME elimination from Rafael Wysocki:
"This removes the last few uses of CONFIG_PM_RUNTIME introduced
recently and makes that config option finally go away.
CONFIG_PM will be available directly from the menu now and also it
will be selected automatically if CONFIG_SUSPEND or CONFIG_HIBERNATION
is set"

Pull SCSI target fixes from Nicholas Bellinger:
"The highlights this merge window include:
- Allow target fabric drivers to function as built-in. (Roland)
- Fix tcm_loop multi-TPG endpoint nexus bug. (Hannes)
- Move per device config_item_type into se_subsystem_api, allowing
configfs attributes to be defined at module_init time. (Jerome +
nab)
- Convert existing IBLOCK/FILEIO/RAMDISK/PSCSI/TCMU drivers to use
external configfs attributes. (nab)
- A number of iser-target fixes related to active session + network
portal shutdown stability during extended stress testing. (Sagi +
Slava)
- Dynamic allocation of T10-PI contexts for iser-target, fixing a
potentially bogus iscsi_np->tpg_np pointer reference in >= v3.14
code. (Sagi)
- iser-target performance + scalability improvements. (Sagi)
- Fixes for SPC-4 Persistent Reservation AllRegistrants spec
compliance. (Ilias + James + nab)
- Avoid potential short kern_sendmsg() in iscsi-target for now until
Al's conversion to use msghdr iteration is merged post -rc1.
(Viro)
Also, Sagi has requested a number of iser-target patches (9) that
address stability issues he's encountered during extended stress
testing be considered for v3.10.y + v3.14.y code. Given the amount of
LOC involved, it will certainly require extra backporting effort.
Apologies in advance to Greg-KH & Co on this. Sagi and I will be
working post-merge to ensure they each get applied correctly"

Pull x86 apic updates from Thomas Gleixner:
"After stopping the full x86/apic branch, I took some time to go
through the first block of patches again, which are mostly cleanups
and preparatory work for the irqdomain conversion and ioapic hotplug
support.
Unfortunaly one of the real problematic commits was right at the
beginning, so I rebased this portion of the pending patches without
the offenders.
It would be great to get this into 3.19. That makes reworking the
problematic parts simpler. The usual tip testing did not unearth any
issues and it is fully bisectible now.
I'm pretty confident that this wont affect the calmness of the xmas
season.
Changes:
- Split the convoluted io_apic.c code into domain specific parts
(vector, ioapic, msi, htirq)
- Introduce proper helper functions to retrieve irq specific data
instead of open coded dereferencing of pointers
- Preparatory work for ioapic hotplug and irqdomain conversion
- Removal of the non functional pci-ioapic driver
- Removal of unused irq entry stubs
- Make native_smp_prepare_cpus() preemtible to avoid GFP_ATOMIC
allocations for everything which is called from there.
- Small cleanups and fixes"
