When compiling kprobes-test-arm.c the following error has been observed
/tmp/ccoT403o.s:21439: Error: bad immediate value for offset (4168)
This is caused by the compiler spilling it's literal pool too far away
from the site which is trying to reference it with a PC relative load.
This arises because the compiler is underestimating the size of the
inline assembler code present, which apparently it approximates as 4
bytes per line or instruction.
We fix this problem by moving the operations which generate more than
4 bytes out of the text section. Specifically, moving the .ascii
directives to the .rodata section.

On some platforms with no power management capabilities, the hotplug
implementation is allowed to return from a smp_ops.cpu_die() call as a
function return. Upon a CPU onlining event, the KVM CPU notifier tries
to reinstall the hyp stub, which fails on platform where no reset took
place following a hotplug event, with the message:
CPU1: smp_ops.cpu_die() returned, trying to resuscitate
CPU1: Booted secondary processor
Kernel panic - not syncing: unexpected prefetch abort in Hyp mode at: 0x80409540
unexpected data abort in Hyp mode at: 0x80401fe8
unexpected HVC/SVC trap in Hyp mode at: 0x805c6170
since KVM code is trying to reinstall the stub on a system where it is
already configured.
To prevent this issue, this patch adds a check in the KVM hotplug
notifier that detects if the HYP stub really needs re-installing when a
CPU is onlined and skips the installation call if the stub is already in
place, which means that the CPU has not been reset.

Previously, the TI clock driver initialized all the clocks hierarchically
under each separate clock provider node. Now, each clock that requires
IO access will instead check their parent node to find out which IO range
to use.
This patch allows the TI clock driver to use a few new features provided
by the generic of_clk_init, and also allows registration of clock nodes
outside the clock hierarchy (for example, any external clocks.)

Here's our last set of fixes for 3.17. Most of these are for TI platforms,
fixing some noisy Kconfig issues, runtime clock and power issues on
several platforms and NAND timings on DRA7.
There are also a couple of bug fixes for i.MX, one for QCOM and a small
fix to avoid section mismatch noise on PXA.
Diffstat looks large, partially due to some tables being updated and
thus touching many lines. The qcom gsbi change also restructures clock
management a bit and thus touches a bunch of lines.
All in all, a bit more changes than we'd like at this point, but nothing
stands out as risky either so it seems like the right thing to send it
up now instead of holding it to the merge window.

CALLER_ADDRESSx for x > 1 returns NULL which doesn't do much harm.

The ASM below does not compile with clang and is not the way that the mcr
command is used in other parts of the kernel.

There are other forms that are supported on different ARM instruction sets but
generally the kernel just uses mcr as it is supported in all ARM instruction
sets.
