Commit 14fd8ed0a7 ("ARM: mvebu: Relocate Armada 370/XP PCIe
device tree nodes") relocated the PCIe controller DT nodes one level
up in the Device Tree, to reflect a more correct representation of the
hardware introduced by the mvebu-mbus Device Tree binding.
However, while most of the boards were properly adjusted accordingly,
the Armada 370 DB board was left unchanged, and therefore, PCIe is
seen as not enabled on this board. This patch fixes that by moving the
PCIe controller node one level-up in armada-370-db.dts.

The Armada XP provides a mechanism called "virtual CPU registers" or
"per-CPU register banking", to access the per-CPU registers of the
current CPU, without having to worry about finding on which CPU we're
running. CPU0 has its registers at 0x21800, CPU1 at 0x21900, CPU2 at
0x21A00 and CPU3 at 0x21B00. The virtual registers accessing the
current CPU registers are at 0x21000.
However, in the Device Tree node that provides the register addresses
for the coherency unit (which is responsible for ensuring coherency
between processors, and I/O coherency between processors and the
DMA-capable devices), a mistake was made: the CPU0-specific registers
were specified instead of the virtual CPU registers. This means that
the coherency barrier needed for I/O coherency was not behaving
properly when executed from a CPU different from CPU0. This patch
fixes that by using the virtual CPU registers.

commit b8d181e408 (staging: drm/imx: add drm plane support) added a file

ERROR: "ipu_plane_enable" [drivers/staging/imx-drm/ipuv3-crtc.ko] undefined!
Additionally, it added a call to imx_drm_crtc_id which also fails with a

I broke `s626_set_dac()` by changing the type of the `dacdata` parameter
from `short` to `unsigned short`. It's actually designed to take a
signed value in the range -0x1fff to +0x2000 although values above
0x1fff get clamped to 0x1fff. (We could change the `maxdata` value to
0x1ffe to avoid the clamping, but `maxdata` values are usually a power
of 2 minus 1.) The bug results in all negative values passed to the
function being changed to +0x1fff by the clamp. Change the parameter
type to `int16_t` to fix the problem.

A common security idiom is to hangup the current tty (via vhangup())
after forking but before execing a root shell. This hangs up any
existing opens which other processes may have and ensures subsequent
opens have the necessary permissions to open the root shell tty/pty.
Reset the TTY_HUPPED state after the driver has successfully
returned the opened tty (perform the reset while the tty is locked
to avoid racing with concurrent hangups).
