Subject: [PATCH 4.3 030/125] ARM: pxa: remove incorrect __init annotation on pxa27x_set_pwrmode

4.3-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Arnd Bergmann <arnd@...db.de>

commit 54c09889bff6d99c8733eed4a26c9391b177c88b upstream.

The z2 machine calls pxa27x_set_pwrmode() in order to power off
the machine, but this function gets discarded early at boot because
it is marked __init, as pointed out by kbuild:

WARNING: vmlinux.o(.text+0x145c4): Section mismatch in reference from the function z2_power_off() to the function .init.text:pxa27x_set_pwrmode()
The function z2_power_off() references
the function __init pxa27x_set_pwrmode().
This is often because z2_power_off lacks a __init
annotation or the annotation of pxa27x_set_pwrmode is wrong.

This removes the __init section modifier to fix rebooting and the
build error.
