Per Hyper-V specification (and as required by Hyper-V-aware guests),
SynIC provides 4 per-vCPU timers. Each timer is programmed via a pair
of MSRs, and signals expiration by delivering a special format message
to the configured SynIC message slot and triggering the corresponding
synthetic interrupt.
Note: as implemented by this patch, all periodic timers are "lazy"
(i.e. if the vCPU wasn't scheduled for more than the timer period the
timer events are lost), regardless of the corresponding configuration
MSR. If deemed necessary, the "catch up" mode (the timer period is
shortened until the timer catches up) will be implemented later.
Changes v2:
* Use remainder to calculate periodic timer expiration time

The SynIC message protocol mandates that the message slot is claimed
by atomically setting message type to something other than HVMSG_NONE.
If another message is to be delivered while the slot is still busy,
message pending flag is asserted to indicate to the guest that the
hypervisor wants to be notified when the slot is released.
To make sure the protocol works regardless of where the message
sources are (kernel or userspace), clear the pending flag on SINT ACK
notification, and let the message sources compete for the slot again.

Adds support for using a OMAP dual-mode timer with PWM capability
as a Linux PWM device. The driver controls the timer by using the
dmtimer API.
Add a platform_data structure for each pwm-omap-dmtimer nodes containing
the dmtimers functions in order to get driver not rely on platform
specific functions.

We currently can't unload omap2430 MUSB platform glue driver module and
this cause issues for fixing the MUSB code further. The reason we can't
remove omap2430 is because it uses the PHY functions and also exports the
omap_musb_mailbox function that some PHY drivers are using.
Let's fix the issue by exporting a more generic musb_mailbox function
from the MUSB core and allow platform glue layers to register phy_callback
function as needed.
And now we can now also get rid of the include/linux/musb-omap.h.

Change behavior during registration of gadgets and
gadget drivers in udc-core. Instead of previous
approach when for successful probe of usb gadget driver
at least one usb gadget should be already registered
use another one where gadget drivers and gadgets
can be registered in udc-core independently.
Independent registration of gadgets and gadget drivers
is useful for built-in into kernel gadget and gadget
driver case - because it's possible that gadget is
really probed only on late_init stage (due to deferred
probe) whereas gadget driver's probe is silently failed
on module_init stage due to no any UDC added.
Also it is useful for modules case - now there is no
difference what module to insert first: gadget module
or gadget driver one.

The ARM RealView PB11MPCore reference design has some special
bits in a system controller register to set up the GIC in one
of three modes: legacy, new with DCC, new without DCC. The
register is also used to enable FIQ.
Since the platform will not boot unless this register is set
up to "new with DCC" mode, we need a special quirk to be
compiled-in for the RealView platforms.
If we find the right compatible string on the GIC TestChip,
we enable this quirk by looking up the system controller and
enabling the special bits.
We depend on the CONFIG_REALVIEW_DT Kconfig symbol as the old
boardfile code has the same fix hardcoded, and this is only
needed for the attempts to modernize the RealView code using
device tree.
After fixing this, the PB11MPCore boots with device tree
only.

We almost have all the needed bits requiredable to create a irq domain
on top of a MSI domain.
For this, we enable a few things:
- the virq is stored in the msi_desc
- device, msi_alloc_info and domain-specific data
are stored in the platform_priv_data structure
- we introduce a new API for platform-msi:
/* Create a MSI-based domain */
struct irq_domain *
platform_msi_create_device_domain(struct device *dev,
unsigned int nvec,
irq_write_msi_msg_t write_msi_msg,
const struct irq_domain_ops *ops,
void *host_data);
/* Allocate MSIs in an MSI domain */
int platform_msi_domain_alloc(struct irq_domain *domain,
unsigned int virq,
unsigned int nr_irqs);
/* Free MSIs from an MSI domain */
void platform_msi_domain_free(struct irq_domain *domain,
unsigned int virq,
unsigned int nvec);
/* Obtain the host data passed to platform_msi_create_device_domain */
void *platform_msi_get_host_data(struct irq_domain *domain);
platform_msi_create_device_domain() is a hybrid of irqdomain creation
and interrupt allocation, creating a domain backed by the MSIs associated
to a device. IRQs can then be allocated in that domain using
platform_msi_domain_alloc().
This now allows a wired irq to MSI bridge to be created.

There is code in ssb fetching "invariants" that is basically a set of
board specific data. Every host requires its own implementation of
reading function. In ssb we have support for PCI, PCMCIA & SDIO.
For some (historical?) reason code reading "invariants" for SoC was
placed in arch code and provided by a callback. This is not needed
nowadays, so lets move that into ssb. This way we keep all "invariants"
functions in a single module making code cleaner.

Merge "omap fixes for 81xx for v4.5 merge window" from Tony Lindgren:
Fixes for ti81xx for v4.5 merge window. We have hp t410 already booting
in mainline kernel with it's bootloader configured clocks. However,
trying to boot dm814x-evm uncovered all kind of issues with the timer
clock. To keep t410 booting, these issues need to be fixed in a specific
order and this branch contains both device tree and code changes.
To summarize the changes, we had missing ranges for clocks to probe,
missing aliase for clocks, wrong registers for divder clocks, and bad
address for the control module. All these went unnoticed earlier as
things worked without errors by luck and I did not pay much attention
to them until I got hold of a dm814x-evm and I noticed it did not boot.
As these are fixes for features that never worked, these can wait for
v4.5 merge window no problem.

Add skb_csum_offload_chk driver helper function to determine if a
device with limited checksum offload capabilities is able to offload the
checksum for a given packet.
This patch includes:
- The skb_csum_offload_chk function. Returns true if checksum is
offloadable, else false. Optionally, in the case that the checksum
is not offloable, the function can call skb_checksum_help to resolve
the checksum. skb_csum_offload_chk also returns whether the checksum
refers to an encapsulated checksum.
- Definition of skb_csum_offl_spec structure that caller uses to
indicate rules about what it can offload (e.g. IPv4/v6, TCP/UDP only,
whether encapsulated checksums can be offloaded, whether checksum with
IPv6 extension headers can be offloaded).
- Ancilary functions called skb_csum_offload_chk_help,
skb_csum_off_chk_help_cmn, skb_csum_off_chk_help_cmn_v4_only.

The name NETIF_F_ALL_CSUM is a misnomer. This does not correspond to the

features of a device.

- Changes instances of NETIF_F_ALL_CSUM to NETIF_F_CSUM_MASK (where
NETIF_F_ALL_CSUM is being used as a mask).
- Changes bonding, sfc/efx, ipvlan, macvlan, vlan, and team drivers to

In theory it could still be used on R-Car Gen1 SoCs, but that would

When we try to compile a clocksource driver with the COMPILE_TEST option,

Currently we have two policies for deciding when to signal the host:
One based on the ring buffer state and the other based on what the
VMBUS client driver wants to do. Consider the case when the client
wants to explicitly control when to signal the host. In this case,
if the client were to defer signaling, we will not be able to signal
the host subsequently when the client does want to signal since the
ring buffer state will prevent the signaling. Implement logic to
have only one signaling policy in force for a given channel.

This patch adds /sys/kernel/debug/acpi/acpidbg, which can be used by
userspace programs to access ACPICA debugger functionalities.
Known issue:
1. IO flush support
acpi_os_notify_command_complete() and acpi_os_wait_command_ready() can
be used by acpi_dbg module to implement .flush() filesystem operation.
While this patch doesn't go that far. It then becomes userspace tool's
duty now to flush old commands before executing new batch mode commands.
