commit: 8f945a33 (genirq: Move kstat_incr_irqs_this_cpu() to core)
unearthed the following:
arch/s390/kernel/irq.c: In function 'init_IRQ':

[-Werror=implicit-function-declaration]

[-Werror=implicit-function-declaration]
....
cc1: some warnings being treated as errors
The reason is that those files require linux/irq.h and magically
pulled that in via linux/kernel_stat.h
The commit above got rid of the pointless include of linux/irq.h in
linux/kernel_stat.h and therefor broke the build.
Include linux/irq.h

The user space interface does not filter out offline cpus. It merily
verifies that the mask contains at least one online cpu. So the
selector in the irq chip implementation needs to make sure to pick
only an online cpu because otherwise:
Offline Core 1
Set affinity to 0xe
Selector will pick first set bit, i.e. core 1

The vmbus/hyperv interrupt handling is another complete trainwreck and
probably the worst of all currently in tree.
If CONFIG_HYPERV=y then the interrupt delivery to the vmbus happens
via the direct HYPERVISOR_CALLBACK_VECTOR. So far so good, but:
The driver requests first a normal device interrupt. The only reason
to do so is to increment the interrupt stats of that device
interrupt. For no reason it also installs a private flow handler.
We have proper accounting mechanisms for direct vectors, but of
course it's too much effort to add that 5 lines of code.
Aside of that the alloc_intr_gate() is not protected against
reallocation which makes module reload impossible.
Solution to the problem is simple to rip out the whole mess and
implement it correctly.
First of all move all that code to arch/x86/kernel/cpu/mshyperv.c and
merily install the HYPERVISOR_CALLBACK_VECTOR with proper reallocation
protection and use the proper direct vector accounting mechanism.

Warn if any PIRQ cannot be bound to an event channel. Remove the check
for irq_desc->action. This hypercall never fails in practice so we can
emit a warning unconditionally.
Remove a check for a valid irq desc. The only caller of
xen_destroy_irq() will only do so if the irq was previously fully
setup, which means the descriptor has been allocated as well.

This reverts commit 40b367d95fb3d60fc1edb9ba8f6ef52272e48936.
Russell King has raised the idea of creating a proper PMU driver for
this SoC that would incorporate the functionality currently in this
driver. It would also cover the use case for the graphics subsystem on
this SoC.
To prevent having to maintain the devicetree ABI for this limited
interrupt-handler driver, we revert the driver before it hits a mainline
tagged release (eg v3.15).

The new Armada 375 and Armada 38x Marvell SoCs are based on Cortex-A9
CPU cores and use the ARM GIC as their main interrupt controller.
However, for various purposes (wake-up from suspend, MSI interrupts),
they have kept a separate MPIC interrupt controller, acting as a slave
to the GIC. This MPIC was already used as the primary controller on
previous Marvell SoCs, so this commit extends the existing driver to
allow the MPIC to be used as a GIC slave.

Introduce a helper function to handle the MSI interrupts. This makes
the code more readable. In addition, this will allow to introduce a
chained IRQ handler mechanism, which is needed in situations where the
MPIC is used as a slave to another interrupt controller.

Currently, of_match_node compares each given match against all node's
compatible strings with of_device_is_compatible.
To achieve multiple compatible strings per node with ordering from
specific to generic, this requires given matches to be ordered from
specific to generic. For most of the drivers this is not true and also
an alphabetical ordering is more sane there.
Therefore, this patch introduces a function to match each of the node's
compatible strings against all given compatible matches without type and
name first, before checking the next compatible string. This implies
that node's compatibles are ordered from specific to generic while
given matches can be in any order. If we fail to find such a match
entry, then fall-back to the old method in order to keep compatibility.

This reverts commit 105353145eafb3ea919f5cdeb652a9d8f270228e.
Stephen Chivers reported this is broken as we will get a match
entry '.type = "serial"' instead of the '.compatible = "ns16550"'
in the following scenario:
serial0: serial@4500 {
compatible = "fsl,ns16550", "ns16550";
}
struct of_device_id of_platform_serial_table[] = {
{ .compatible = "ns8250", .data = (void *)PORT_8250, },
{ .compatible = "ns16450", .data = (void *)PORT_16450, },
{ .compatible = "ns16550a", .data = (void *)PORT_16550A, },
{ .compatible = "ns16550", .data = (void *)PORT_16550, },
{ .compatible = "ns16750", .data = (void *)PORT_16750, },
{ .compatible = "ns16850", .data = (void *)PORT_16850, },
...
{ .type = "serial", .data = (void *)PORT_UNKNOWN, },
{ /* end of list */ },
};
So just revert this patch, we will use another implementation to find
the best compatible match in a follow-on patch.

The CMD_T_FAILED flag is set used in one place to record the result of a

Because the offload mechanism can fall back to a standard transfer,
having two seperate initialization states is unfortunate. Let's just
have one state which does things consistently. This fixes a bug where
some preparation was missing when the fallback happened. And it makes
the code much easier to follow. To implement this, we put the check
if offload is possible at the top of the offload setup function.

Pull timer fixes from Thomas Gleixner:
"The following trilogy of patches brings you:
- fix for a long standing math overflow issue with HZ < 60
- an onliner fix for a corner case in the dreaded tick broadcast
mechanism affecting a certain range of AMD machines which are
infested with the infamous automagic C1E power control misfeature
- a fix for one of the ARM platforms which allows the kernel to
proceed and boot instead of stupidly panicing for no good reason.
The patch is slightly larger than necessary, but it's less ugly
than the alternative 5 liner"
* 'timers-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
tick: Clear broadcast pending bit when switching to oneshot

Since there may be other clocksources available, this driver should not
trigger a panic simply because it can not determine the frequency of an
external clock. This change refactors the driver to allow a warning to
be printed in this case instead.

Enabling some of the mvebu platforms in the multiplatform config for ARM
enabled these drivers, which also triggered a bunch of warnings when LPAE
is enabled (thus making phys_addr_t 64-bit).
Most changes are switching printk formats, but also a bit of changes to what
used to be array-based pointer arithmetic that could just be done with the
address types instead.
The warnings were:

Add devm_phy_optional_get and phy_optional_get, which should be used
when the phy is optional. They does not return an error when the phy
does not exist, rather they returns NULL, which is considered as a valid
phy, but results in NOPs when used with the consumer API.

The common clock framework considers NULL a valid clock
reference. This makes handling optional clocks simple, in that if the
optional clock is not available, a NULL reference can be used in the
place of a real clock, simplifying the clock consumer.
Extend this concept to the phy consumer API. A NULL can be passed to
the release calls, the phy_init() and phy_exit() calls, and
phy_power_on() and phy_power_off() and a NOP is performed.

xHCI 1.0 hosts have a set of requirements on how to align transfer
buffers on the endpoint rings called "TD fragment" rules. When the
ax88179_178a driver added support for scatter gather in 3.12, with
commit 804fad45411b48233b48003e33a78f290d227c8 "USBNET: ax88179_178a:
enable tso if usb host supports sg dma", it broke the device under xHCI
1.0 hosts. Under certain network loads, the device would see an
unexpected short packet from the host, which would cause the device to
stop sending ethernet packets, even through USB packets would still be
sent.
Commit 35773dac5f86 "usb: xhci: Link TRB must not occur within a USB
payload burst" attempted to fix this. It was a quick hack to partially
implement the TD fragment rules. However, it caused regressions in the
usb-storage layer and userspace USB drivers using libusb. The patches
to attempt to fix this are too far reaching into the USB core, and we
really need to implement the TD fragment rules correctly in the xHCI
driver, instead of continuing to wallpaper over the issues.
Disable arbitrarily-aligned scatter-gather in the xHCI driver for 1.0
hosts. Only the ax88179_178a driver checks the no_sg_constraint flag,
so don't set it for 1.0 hosts. This should not impact usb-storage or
usbfs behavior, since they pass down max packet sized aligned sg-list
entries (512 for USB 2.0 and 1024 for USB 3.0).

People sometimes create their own custom-configured kernels and forget
to enable CONFIG_SCSI_MULTI_LUN. This causes problems when they plug
in a USB storage device (such as a card reader) with more than one
LUN.
Fortunately, we can tell fairly easily when a storage device claims to
have more than one LUN. When that happens, this patch asks the SCSI
layer to probe all the LUNs automatically, regardless of the config
setting.
The patch also updates the Kconfig help text for usb-storage,
explaining that CONFIG_SCSI_MULTI_LUN may be necessary.
