Make the "fast" syscall return path fast again. The addition of IRQ
tracing and context tracking has made this path grossly inefficient.
We can do much better if these options are enabled if we save the
syscall return code on the stack - we then don't need to save a bunch
of registers around every single callout to C code.

ARM previously stored the msi_controller pointer in its sysdata, struct
pci_sys_data, and implemented pcibios_msi_controller() to retrieve it.
That made PCI host controller drivers specific to ARM because they had to
put the msi_controller pointer in the ARM-specific pci_sys_data.
There is now a generic mechanism, pci_scan_root_bus_msi(), for giving the
msi_controller pointer to the PCI core. Use this for all ARM systems and
for the DesignWare and Xilinx PCI host controller drivers.
This removes an ARM dependency from the DesignWare, DRA7xx, EXYNOS, i.MX6,
Keystone, Layerscape, SPEAr13xx, and Xilinx drivers.

In the ARM PCI bios32 layer, failures to dynamically allocate pci_sys_data
for a PCI bus, or a PCI bus scan failure have to be considered serious
warnings but they should not trigger a system panic so that at least the

ARM guests are always HVM. The current implementation is assuming a 1:1
mapping which is only true for DOM0 and may not be at all in the future.
Furthermore, all the helpers but arbitrary_virt_to_machine are used in
x86 specific code (or only compiled for).
The helper arbitrary_virt_to_machine is only used in PV specific code.
Therefore we should never call the function.
Add a BUG() in this helper and drop all the others.

The commit 6f6c15ef91 "xen/pvhvm: Remove
the xen_platform_pci int." makes the x86 version of
xen_pci_platform_unplug static.
Therefore we don't need anymore to define a dummy xen_pci_platform_unplug
for ARM.

Currently, the event channel rebind code is gated with the presence of
the vector callback.
The virtual interrupt controller on ARM has the concept of per-CPU
interrupt (PPI) which allow us to support per-VCPU event channel.
Therefore there is no need of vector callback for ARM.
Xen is already using a free PPI to notify the guest VCPU of an event.
Furthermore, the xen code initialization in Linux (see
arch/arm/xen/enlighten.c) is requesting correctly a per-CPU IRQ.
Introduce new helper xen_support_evtchn_rebind to allow architecture
decide whether rebind an event is support or not. It will always return
true on ARM and keep the same behavior on x86.
This is also allow us to drop the usage of xen_have_vector_callback
entirely in the ARM code.

The conversion of the wakeupgen irqchip to hierarchical irq domains
failed to provide a mechanism to properly set the trigger type of an
interrupt.
The wakeupgen irq chip itself has no mechanism and therefor no
irq_set_type() callback. The code before the conversion relayed the
trigger configuration directly to the underlying GIC.
Restore the correct behaviour by setting the wakeupgen irq_set_type
callback to irq_chip_set_type_parent(). This propagates the
set_trigger() call to the underlying GIC irqchip.

The sp810 clk driver is calling the clk consumer APIs from
clk_prepare ops to change the parent to a 1 MHz fixed rate clock
for each of the clocks that the driver provides. Use
assigned-clock-parents for this instead of doing it in the driver
to avoid using the consumer API in provider code. This also
allows us to remove the usage of clk provider APIs that take a
struct clk as an argument from the sp810 driver.

Add early fixmap support, initially to support permanent, fixed
mapping support for early console. A temporary, early pte is
created which is migrated to a permanent mapping in paging_init.
This is also needed since the attributes may change as the memory
types are initialized. The 3MiB range of fixmap spans two pte
tables, but currently only one pte is created for early fixmap
support.

U-Boot is often used to boot the kernel on ARM boards, but uImage
is not built by "make all", so we are often inclined to do
"make all uImage" to generate DTBs, modules and uImage in a single

"make all uImage" could generate an invalid uImage if it is run with
the parallel option (-j).
You can reproduce this problem with the following procedure:
[1] First, build "all" and "uImage" separately.
You will get a valid uImage

Please notice the uImage is extremely small when this issue is
encountered. Besides, "Kernel: arch/arm/boot/zImage is ready" is
displayed twice, before and after the uImage log.
The root cause of this is the race condition between zImage and
uImage. Actually, uImage depends on zImage, but the dependency
between the two is only described in arch/arm/boot/Makefile.
Because arch/arm/boot/Makefile is not included from the top-level
Makefile, it cannot know the dependency between zImage and uImage.
Consequently, when we run make with the parallel option, Kbuild
updates vmlinux first, and then two different threads descends into
the arch/arm/boot/Makefile almost at the same time, one for updating
zImage and the other for uImage. While one thread is re-generating
zImage, the other also tries to update zImage before creating uImage
on top of that. zImage is overwritten by the slower thread and then
uImage is created based on the half-written zImage.
This is the reason why "Kernel: arch/arm/boot/zImage is ready" is
displayed twice, and a broken uImage is created.
The same problem could happen on bootpImage.
This commit adds dependencies among Image, zImage, uImage, and
bootpImage to arch/arm/Makefile, which is included from the
top-level Makefile.

A smallish batch of fixes, a little more than expected this late, but
all fixes are contained to their platforms and seem reasonably low risk:
- A somewhat large SMP fix for ux500 that still seemed warranted to include here
- OMAP DT fixes for pbias regulator specification that broke due to some DT
reshuffling
- PCIe IRQ routing bugfix for i.MX
- Networking fixes for keystone
- Runtime PM for OMAP GPMC
- A couple of error path bug fixes for exynos

This change is a code reorganization. Here we introduce
serial_imx_enable_wakeup() helper function to do
the job of configuring and preparing wakeup sources
on imx serial device. The idea is to allow other
parts of the code to call this function whenever
the device is known to go to idle.

This callback is expected to do the same as enter() but it has to
guarantee that interrupts aren't enabled at any point in its execution,
as the tick is frozen.
It will be called when the system goes to suspend-to-idle and will
reduce power usage because CPUs won't be awaken for unnecessary IRQs.
By setting the CPUIDLE_FLAG_TIMER_STOP flag, we can reuse the same code
for both the enter() and enter_freeze() callbacks.

Cortex-A9 SoCs and actually enabling usb on the rk3066-marsboard,
Two more veyron-devices - namely Speedy and Minnie and a fix for
the tsadc.
One slightly more interesting fix is the blocking of the last
16MB of memory on 4GB rk3288 devices. The rk3288 cannot use this
area for dma operations, so things like the mmc or usb controllers
regularly fail when trying to read data. This solution mimicks the
solution from the ChromeOS kernel, who also do not seem to have
found a better solution yet. Here it only moves to the devicetree.
As this issue is also present on the arm64 rk3368, any future
better solution to this problem would need to describe this in
the devicetree as well and could then remove this block.

reason resuming from suspend worked sucessfully on the rk3288-evb
but not on other boards, like veyron-devices. Two problems seem
to have existed. For one the stabilization delays for pmic and
oscillator may have been to short and secondly the shallow
suspend seems to need GPIO wakups enabled. Normally this should
be covered by the more generic ARMINT wakeups already and
the reason for this is still investigated at Rockchip, but
meanwhile this makes boards actually resume.

reason resuming from suspend worked sucessfully on the rk3288-evb
but not on other boards, like veyron-devices. Two problems seem
to have existed. For one the stabilization delays for pmic and
oscillator may have been to short and secondly the shallow
suspend seems to need GPIO wakups enabled. Normally this should
be covered by the more generic ARMINT wakeups already and
the reason for this is still investigated at Rockchip, but
meanwhile this makes boards actually resume.

clockevents core, the earlier 'set-mode' interface is marked obsolete
now.
This also enables us to implement callbacks for new states of clockevent
