[PATCH AUTOSEL 4.4 03/68] ARM: dts: imx53-voipac-dmm-668: Fix memory node duplication

[Sasha Levin]

From: Fabio Estevam <festevam@gmail.com>

[ Upstream commit 998a84c27a7f3f9133d32af64e19c05cec161a1a ]

imx53-voipac-dmm-668 has two memory nodes, but the correct representation
would be to use a single one with two reg entries - one for each RAM chip
select, so fix it accordingly.

[PATCH AUTOSEL 4.4 06/68] arm64: smp: Handle errors reported by the firmware

[Sasha Levin]

From: Suzuki K Poulose <Suzuki.Poulose@arm.com>

[ Upstream commit f357b3a7e17af7736d67d8267edc1ed3d1dd9391 ]

The __cpu_up() routine ignores the errors reported by the firmware
for a CPU bringup operation and looks for the error status set by the
booting CPU. If the CPU never entered the kernel, we could end up
in assuming stale error status, which otherwise would have been
set/cleared appropriately by the booting CPU.

[PATCH AUTOSEL 4.4 08/68] ARM: ks8695: fix section mismatch warning

[Sasha Levin]

From: Arnd Bergmann <arnd@arndb.de>

[ Upstream commit 4aa64677330beeeed721b4b122884dabad845d66 ]

WARNING: vmlinux.o(.text+0x13250): Section mismatch in reference from the function acs5k_i2c_init() to the (unknown reference) .init.data:(unknown)
The function acs5k_i2c_init() references
the (unknown reference) __initdata (unknown).
This is often because acs5k_i2c_init lacks a __initdata
annotation or the annotation of (unknown) is wrong.

[PATCH AUTOSEL 4.4 48/68] net: stmicro: fix a missing check of clk_prepare

[Sasha Levin]

From: Kangjie Lu <kjlu@umn.edu>

[ Upstream commit f86a3b83833e7cfe558ca4d70b64ebc48903efec ]

clk_prepare() could fail, so let's check its status, and if it fails,
return its error code upstream.
