Subject: [PATCH] sctp: fix typo in default SCTP cookie choice
Commit 0d0863b0 (sctp: Change defaults on cookie hmac selection)
introduced a choice configuration option to select the default SCTP
cookie hashing algorithm, a typo was introduced for the default choice.
This is an issue when running make oldconfig because an explicit choice
number must be entered since no default is available. This patch fixes
the typo, thus providing a valid default choice.

If the Orion WDT driver is built as a module, an opps occurs during
clk lookup when calling mvebu_clk_gating_get_src(). Remove the
inappropriate __init tag so the function is available for modules
after kernel init.

From: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
When mv_xor_channel_add() fails for one XOR channel, we jump to the
err_channel_add label to clean up all previous channels that had been
initialized correctly. Unfortunately, while handling this error
condition, we were disposing the IRQ mapping before calling
mv_xor_channel_remove() (which does the free_irq()), which is
incorrect.
Instead, do things properly in the reverse order of the
initialization: first remove the XOR channel (so that free_irq() is
done), and then dispose the IRQ mapping.
This avoids ugly warnings when for some reason one of the XOR channel
fails to initialize.

From: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
When a channel fails to initialize, we release all ressources,
including clocks. However, a XOR unit is not necessarily associated to
a clock (some variants of Marvell SoCs have a clock for XOR units,
some don't), so we shouldn't unconditionally be releasing the clock.
Instead, just like we do in the mv_xor_remove() function, we should
check if one clock was found before releasing it.

with WT enable
This patch fixes a bug for Aurora L2 cache controller when the
write-through mode is enable. For the clean operation even if we don't
have to flush the lines we still need to invalidate them.

The use of writel instead of writel_relaxed lead to deadlock in some

as it was done in the rest of this driver fixes this bug.

Subject: [PATCH] arm: mvebu: Use dw-apb-uart instead of ns16650 as UART
driver
The UART controller used in the Armada 370 and Armada XP SoCs is the
Synopsys DesignWare 8250 (aka Synopsys DesignWare ABP UART). The
improper use of the ns16550 can lead to a kernel oops during boot if
a character is sent to the UART before the initialization of the
driver. The DW APB has an extra interrupt that gets raised when
writing to the LCR when busy. This explains why we need to use
dw-apb-uart driver to handle this.
