Pass PCOMMIT CPU feature to guest to enable PCOMMIT instruction
Currently we do not catch pcommit instruction for L1 guest and
allow L1 to catch this instruction for L2 if, as required by the spec,
L1 can enumerate the PCOMMIT instruction via CPUID:
| IA32_VMX_PROCBASED_CTLS2[53] (which enumerates support for the
| 1-setting of PCOMMIT exiting) is always the same as
| CPUID.07H:EBX.PCOMMIT[bit 22]. Thus, software can set PCOMMIT exiting
| to 1 if and only if the PCOMMIT instruction is enumerated via CPUID
The spec can be found at

Uniprocessor 32-bit randconfigs can disable the local APIC, and posted
interrupts require reserving a vector on the LAPIC, so they are
incompatible.

In order to enable userspace PIC support, the userspace PIC needs to
be able to inject local interrupts even when the APICs are in the
kernel.
KVM_INTERRUPT now supports sending local interrupts to an APIC when
APICs are in the kernel.
The ready_for_interrupt_request flag is now only set when the CPU/APIC
will immediately accept and inject an interrupt (i.e. APIC has not
masked the PIC).
When the PIC wishes to initiate an INTA cycle with, say, CPU0, it
kicks CPU0 out of the guest, and renedezvous with CPU0 once it arrives
in userspace.
When the CPU/APIC unmasks the PIC, a KVM_EXIT_IRQ_WINDOW_OPEN is
triggered, so that userspace has a chance to inject a PIC interrupt
if it had been pending.
Overall, this design can lead to a small number of spurious userspace
renedezvous. In particular, whenever the PIC transistions from low to
high while it is masked and whenever the PIC becomes unmasked while
it is low.
Note: this does not buffer more than one local interrupt in the
kernel, so the VMM needs to enter the guest in order to complete
interrupt injection before injecting an additional interrupt.
Compiles for x86.
Can pass the KVM Unit Tests.

In order to support a userspace IOAPIC interacting with an in kernel
APIC, the EOI exit bitmaps need to be configurable.
If the IOAPIC is in userspace (i.e. the irqchip has been split), the
EOI exit bitmaps will be set whenever the GSI Routes are configured.
In particular, for the low MSI routes are reservable for userspace
IOAPICs. For these MSI routes, the EOI Exit bit corresponding to the
destination vector of the route will be set for the destination VCPU.
The intention is for the userspace IOAPICs to use the reservable MSI
routes to inject interrupts into the guest.
This is a slight abuse of the notion of an MSI Route, given that MSIs
classically bypass the IOAPIC. It might be worthwhile to add an
additional route type to improve clarity.

Adds KVM_EXIT_IOAPIC_EOI which allows the kernel to EOI
level-triggered IOAPIC interrupts.
Uses a per VCPU exit bitmap to decide whether or not the IOAPIC needs
to be informed (which is identical to the EOI_EXIT_BITMAP field used
by modern x86 processors, but can also be used to elide kvm IOAPIC EOI
exits on older processors).
[Note: A prototype using ResampleFDs found that decoupling the EOI
from the VCPU's thread made it possible for the VCPU to not see a
recent EOI after reentering the guest. This does not match real
hardware.]

The interrupt window is currently checked twice, once in vmx.c/svm.c and
once in dm_request_for_irq_injection. The only difference is the extra
check for kvm_arch_interrupt_allowed in dm_request_for_irq_injection,
and the different return value (EINTR/KVM_EXIT_INTR for vmx.c/svm.c vs.
0/KVM_EXIT_IRQ_WINDOW_OPEN for dm_request_for_irq_injection).
However, dm_request_for_irq_injection is basically dead code! Revive it
by removing the checks in vmx.c and svm.c's vmexit handlers, and
fixing the returned values for the dm_request_for_irq_injection case.

Avoid pointer chasing and memory barriers, and simplify the code
when split irqchip (LAPIC in kernel, IOAPIC/PIC in userspace)
is introduced.

This will avoid an unnecessary trip to ->kvm and from there to the VPIC.

We can reuse the algorithm that computes the EOI exit bitmap to figure
out which vectors are handled by the IOAPIC. The only difference
between the two is for edge-triggered interrupts other than IRQ8
that have no notifiers active; however, the IOAPIC does not have to
do anything special for these interrupts anyway.
This again limits the interactions between the IOAPIC and the LAPIC,
making it easier to move the former to userspace.
Inspired by a patch from Steve Rutherford.

Do not compute TMR in advance. Instead, set the TMR just before the interrupt
is accepted into the IRR. This limits the coupling between IOAPIC and LAPIC.

Taking some inspiration from the arch/arm code, implement the
arch-specific side of the DMA mapping ops using the new IOMMU-DMA layer.
Since there is still work to do elsewhere to make DMA configuration happen
in a more appropriate order and properly support platform devices in the
IOMMU core, the device setup code unfortunately starts out carrying some
workarounds to ensure it works correctly in the current state of things.

The OS should ask Power Firmware (PFW) for the size of the buffer
allocated for the event log, instead of the size of the actual
event log. It then passes the buffer adddress and size to PFW in
the handover process, into which PFW copies the log.

Pull spi updates from Mark Brown:
"Quite a lot of activity in SPI this cycle, almost all of it in drivers
with a few minor improvements and tweaks in the core.
- Updates to pxa2xx to support Intel Broxton and multiple chip selects.
- Support for big endian in the bcm63xx driver.
- Multiple slave support for the mt8173
- New driver for the auxiliary SPI controller in bcm2835 SoCs.
- Support for Layerscale SoCs in the Freescale DSPI driver"

Move all register definitions and structs into the driver. This allows
us dropping the platform_data struct and drop any arch specific
includes. Make use of different device names to identify the version of
the block we have.
Since we now have full control over the message width, we can drop the
size check, which was broken anyway, since it never set ret to any error
code.
Also since we now have no arch depedendent resources, we can now allow
compiling it for any arch, hidden behind COMPILE_TEST.

Pull clk updates from Stephen Boyd:
"The majority of the changes are driver updates and new device support.
The core framework is mostly unchanged this time around, with only a
couple patches to expose a clk provider API and make getting clk
parent names from DT more robust.
Driver updates:
- Support for clock controllers found on Broadcom Northstar SoCs and
bcm2835 SoC
- Support for Allwinner audio clocks
- A few cleanup patches for Tegra drivers and support for the highest
DFLL frequencies on Tegra124
- Samsung exynos7 fixes and improvements
- i.Mx SoC updates to add a few missing clocks and keep debug uart
clocks on during kernel intialization
- Some mediatek cleanups and support for more subsystem clocks
- Support for msm8916 gpu/audio clocks and qcom's GDSC power domain
controllers
- A new driver for the Silabs si514 clock chip"

When CONFIG_CYGNUS is set but CONFIG_COMMON_CLK_IPROC is disabled, the
following link failures are caused:
drivers/built-in.o: In function `cygnus_armpll_init':
:(.init.text+0x1d290): undefined reference to `iproc_armpll_setup'
drivers/built-in.o: In function `cygnus_genpll_clk_init':

drivers/built-in.o: In function `cygnus_lcpll0_clk_init':

drivers/built-in.o: In function `cygnus_mipipll_clk_init':

drivers/built-in.o: In function `cygnus_asiu_init':
:(.init.text+0x1d370): undefined reference to `iproc_asiu_setup'
It is fixed it by always selecting COMMON_CLK_IPROC from
ARCH_BCM_IPROC, and making COMMON_CLK_IPROC a silent option (thus
preventing it from being erroneously disabled by a user).

Add a new type of clocks that can be provided to a peripheral.
In addition to the peripheral clock, this new clock that can use several
input clocks as parents can generate divided rates.
This would allow a peripheral to have finer grained clocks for generating
a baud rate, clocking an asynchronous part or having more
options in frequency.

Its a bit odd that debugfs_create_bool() takes 'u32 *' as an argument,
when all it needs is a boolean pointer.
It would be better to update this API to make it accept 'bool *'
instead, as that will make it more consistent and often more convenient.
Over that bool takes just a byte.
That required updates to all user sites as well, in the same commit
updating the API. regmap core was also using
debugfs_{read|write}_file_bool(), directly and variable types were
updated for that to be bool as well.

Pull USB updates from Greg KH:
"Here is the big USB patchset for 4.4-rc1.
As usual, most of the changes are in the gadget subsystem, and we
removed a host controller for a device that is no longer in existance,
and probably never was even made public. There is also other minor
driver updates and new device ids, full details in the changelog.
All of these have been in linux-next for a while"
