Non-T variants of ARMv4 do not support the bx instruction.
However, __hyp_stub_install is always called from the same
instruction set used to build the bulk of the kernel, so bx should
not be necessary.
This patch uses the traditional "mov pc" instead of bx.

Recently the regs-syscon-power.h header was moved from
mach-s3c64xx/include/mach to mach-s3c64xx/, but cpuidle.c was not
updated to include the header from its new location, which caused
build error with CONFIG_CPU_IDLE enabled.
This patch fixed the problem by updating the include line with

The Armada XP GPIO controller has two ways of notifying interrupts:
using global interrupts or using per-CPU interrupts. In an attempt to
use the best available features, the 'marvell,armadaxp-gpio'
compatible string selects a variant of the gpio-mvebu driver that
makes use of the per-CPU interrupts.
Unfortunately, this doesn't work properly in a SMP context, because we
fall into cases where the GPIO interrupt is enabled on CPU X at the
GPIO controller level, but on CPU Y at the interrupt controller
level. It is not yet clear how to fix that easily.
So for 3.8, our approach is to switch to global interrupts for GPIOs,
so that we do not fall into this per-CPU interrupts problem.
This patch therefore fixes GPIO interrupts on Armada XP
platforms. Without this patch, GPIO interrupts simply do not work
reliably, because their proper operation depends on which CPU the code
requesting the interrupt is running.

This patch fixes some code that implements a work-around to a hardware bug in
the ac97 controller on the pxa27x. A bug in the controller's warm reset
functionality requires that the mfp used by the controller as the AC97_nRESET
line be temporarily reconfigured as a generic output gpio (AF0) and manually
held high for the duration of the warm reset cycle. This is what was done in
the original code, but it was broken long ago by commit fb1bf8cd
([ARM] pxa: introduce processor specific pxa27x_assert_ac97reset())
which changed the mfp to a GPIO input instead of a high output.
The fix requires the ac97 controller to obtain the gpio via gpio_request_one(),
with arguments that configure the gpio as an output initially driven high.
Tested on a palm treo 680 machine. Reportedly, this broken code only prevents a
warm reset on hardware that lacks a pull-up on the line, which appears to be the
case for me.
