After enhancing arm64 FP/SIMD exit handling, ARMv7 VFP exit branch is moved
to guest trap handling. This allows us to keep exit handling flow between both
architectures consistent.

In order to remove the crude hack where we sneak the masked bit
into the timer's control register, make use of the phys_irq_map
API control the active state of the interrupt.
This causes some limited changes to allow for potential error
propagation.

In order to be able to feed physical interrupts to a guest, we need
to be able to establish the virtual-physical mapping between the two
worlds.
The mappings are kept in a set of RCU lists, indexed by virtual interrupts.

As we're about to introduce some serious GIC-poking to the vgic code,
it is important to make sure that we're going to poke the part of
the GIC that belongs to the CPU we're about to run on (otherwise,
we'd end up with some unexpected interrupts firing)...
Introducing a non-preemptible section in kvm_arch_vcpu_ioctl_run
prevents the problem from occuring.

As we now inject the timer interrupt when we're about to enter
the guest, it makes a lot more sense to make sure this happens
before the vgic code queues the pending interrupts.
Otherwise, we get the interrupt on the following exit, which is
not great for latency (and leads to all kind of bizarre issues
when using with active interrupts at the HW level).

Previously, the JIT would reject negative offsets known during code
generation and mishandle negative offsets provided at runtime.
Fix that by calling bpf_internal_load_pointer_neg_helper()
appropriately in the jit_get_skb_{b,h,w} slow path helpers and by forcing
the execution flow to the slow path helpers when the offset is
negative.

To check whether the load should take the fast path or not, the code
would check that (r_skb_hlen - load_order) is greater than the offset
of the access using an "Unsigned higher or same" condition. For
halfword accesses and an skb length of 1 at offset 0, that test is
valid, as we end up comparing 0xffffffff(-1) and 0, so the fast path
is taken and the filter allows the load to wrongly succeed. A similar
issue exists for word loads at offset 0 and an skb length of less than
4.
Fix that by using the condition "Signed greater than or equal"
condition for the fast path code for load orders greater than 0.

This introduces a level of indirection for the debug registers. Instead
of using the sys_regs[] directly we store registers in a structure in
the vcpu. The new kvm_arm_reset_debug_ptr() sets the debug ptr to the
guest context.
Because we no longer give the sys_regs offset for the sys_reg_desc->reg
field, but instead the index into a debug-specific struct we need to
add a number of additional trap functions for each register. Also as the
generic generic user-space access code no longer works we have
introduced a new pair of function pointers to the sys_reg_desc structure
to override the generic code when needed.

This is a precursor for later patches which will need to do more to
setup debug state before entering the hyp.S switch code. The existing
functionality for setting mdcr_el2 has been moved out of hyp.S and now
uses the value kept in vcpu->arch.mdcr_el2.
As the assembler used to previously mask and preserve MDCR_EL2.HPMN I've
had to add a mechanism to save the value of mdcr_el2 as a per-cpu
variable during the initialisation code. The kernel never sets this
number so we are assuming the bootcode has set up the correct value
here.
This also moves the conditional setting of the TDA bit from the hyp code
into the C code which is currently used for the lazy debug register
context switch code.

Commit 2ae416b142b6 ("mm: new mm hook framework") introduced an empty

doesn't need to define mm hooks.
As suggested by Geert Uytterhoeven, this could be cleaned through the use
of a generic header file included via each per architecture

The PowerPC architecture is not impacted here since this architecture has

Currently PCIe DT bindings are broken. PCIe driver can't function
without having a SerDes driver that provide the phy configuration.
On K2E EVM, this causes problem since the EVM has Marvell SATA
controller present and with default values in the SerDes register,
it seems to pass the PCIe link check, but causes issues since
the configuration is not correct. The manifestation is that when
EVM is booted with NFS rootfs, the boot hangs. We shouldn't enable
PCIe on this EVM since to work, SerDes driver has to be present as
well. So by default, the PCIe DT binding should be disabled in SoC
specific DTS. It can be enabled in the board specific DTS when the
SerDes device driver is also present.
So fix the status of PCIe DT bindings in the SoC specific DTS to
"disabled". To enable PCIe, the status should be set to "ok" in
the EVM DTS file when SerDes driver support becomes available in
the upstream tree.

Ux500 is regressing due to commit
a21763a0b1e5a5ab8310f581886d04beadc16616
"pinctrl: nomadik: activate strict mux mode" which disallows
Nomadik GPIO 5 to be muxed in as a level shifter voltage select
pin, as it is currently described as being used for RX on UART1.
The behaviour is correct, instead the hardware config has been
incorrecly specified: UART1 is indeed unused on HREFv60plus and
Snowball and that is why HREFv60plus can use the pins it would
normally occupy as the voltage select line for the MMC/SD
levelshifter (Snowball uses it for I2C4).
The reason UART1 was anyway enabled on these platforms was
probably to secure the port enumeration to userspace. This
can be solved by using aliases (done in a separate patch) so
we can now deactivate UART1 and let MMC/SD use it properly
on HREFv60plus. We explicitly activate it only for the
older HREFprev60 board.
To complete, we set up the pin configuration for these pins
properly in the sdi0 node.

Boot process is halting in midway because some of the necessary voltage
regulators are deemed unused and subsequently powered off, leading to
a completely unresponsive system.
Most of the device nodes had correct voltage regulator attachments.
Yet these nodes had to set stricter enforcement on them through
'regulator-boot-on' and 'regulator-always-on' to function correctly.
The consumers of the regulators this commit affect are the followings:
DCDC1: vdd_1v8 system supply, USB-PHY, and ADC
DCDC2: Core domain
DCDC3: MPU core domain
LDO1: RTC
LDO2: 3v3 IO domain
LDO3: USB-PHY; not a boot-time requirement
LDO4: LCD [16:23]
All but LDO3 need to be always-on for the system to be functional.
Additionally regulator-name properties have been added for the kernel to
display the name from the schematic. This will improve diagnostics.

For Gumstix Overo COMs, the u-boot bootloader typically passes an
argument specifying the default display via the omapdss.def_disp
parameter. When a default display is specified, DSS2 tries to match
this name with either the device tree label (e.g. label=dvi) or,
failing this, the device tree alias (e.g. label=display0). Update the

such that they match the names passed by u-boot.

Driver core sets "default" pinmux on on probe and CAN driver
sets "sleep" pinmux during register. This causes a small window
where the CAN pins are in "default" state with the DCAN module
being disabled.
Change the "default" state to be like sleep so this glitch is
avoided. Add a new "active" state that is used by the driver
when CAN is actually active.

Pull ARM SoC fixes from Kevin Hilman:
"A fairly random colletion of fixes based on -rc1 for OMAP, sunxi and
prima2 as well as a few arm64-specific DT fixes.
This series also includes a late to support a new Allwinner (sunxi)
SoC, but since it's rather simple and isolated to the
platform-specific code, it's included it for this -rc"

Merge "omap fixes against v4.2-rc1" from Tony Lindgren:
Minor fixes for omaps against v4.2-rc1. Mostly just minor dts changes
except for a GPMC fix to not use names for probing devices. Also a
one liner clean-up to remove unecessary return from a void function.
The summary for the changes being:
- Fix probe for GPMC devices by reoving limitations based on device
name
- Remove unnecessary return from a void function
- Revert beaglebone RTC sleep fix, we now have a better fix merged
- Add am4372 EMIF node to fix a warning
- Add am57xx-beagle-x15 power supply to fix USB2 if USB1 is disabled
- Disable rfbi for am4372 as it does not have a driver

The CCI device node was added to vexpress CA15_A7(i.e. TC2) much before
the CCI PMU support and binding was added. This patch adds the missing
PMU node so that CCI PMUs can be used on TC2.

The dts for the CoreTile Express A15x2 A7x3 (TC2) only describes the
PMUs of the Cortex-A15 CPUs, and not the Cortex-A7 CPUs.
Now that we have a mechanism for describing disparate PMUs and their
interrupts in device tree, this patch makes use of these to describe the
PMUs for all CPUs in the system. For consistency, the existing A15 PMU
interrupt-affinity property is reflowed across two lines.

If CONFIG_PM is not set the PU power domain needs to be enabled always,
otherwise there are two failure scenarios which will hang the system if
one of the devices in the PU domain is accessed.
1. New DTs (4.1+) drop the "always-on" property from the PU regulator, so
if it isn't properly enabled by the GPC code it will be disabled at the
end of boot.
2. If the bootloader already disabled the PU domain the GPC explicitly
needs to enable it again, even if the kernel doesn't do any power
management. This is a bit hypothetical, as it requires to boot a
mainline kernel on a downstream bootloader, as no mainline bootloader
disables the PM domains.
