736ad004f8 arm64: tegra: Device tree changes for v4.9-rc1
Add a couple of devices (AGIC, ADMA) on Tegra210 and enable them on
 Smaug. Also enable DPAUX on Smaug to allow the I2C bus that shares pads
 with the DPAUX to be used to access various audio devices. Furthermore,
 enable the XUSB controller on Smaug for USB 3.0 support.
 
 Finally, select PM_GENERIC_DOMAINS for 64-bit Tegra devices to make sure
 devices are probed only after their power partitions have been enabled.

cfeeed279d x86/dumpstack: Allow preemption in show_stack_log_lvl() and dump_trace()
show_stack_log_lvl() and dump_trace() are already preemption safe:

- If they're running in irq or exception context, preemption is already
  disabled and the percpu stack pointers can be trusted.

- If they're running with preemption enabled, they must be running on
  the task stack anyway, so it doesn't matter if they're comparing the
  stack pointer against a percpu stack pointer from this CPU or another
  one: either way it won't match.

0278b34bf1 spi: spidev_test: Fix buffer overflow in unescape()
Sometimes spidev_test crashes with:

    *** Error in `spidev_test': munmap_chunk(): invalid pointer: 0x00022020 ***
    Aborted

or just

    Segmentation fault

This is due to transfer_escaped_string() miscalculating the required
size of the buffer by one byte, causing a buffer overflow in unescape().

Drop the bogus "+ 1" in the strlen() parameter to fix this.

Note that unescape() never copies the zero-terminator of the source
string, so it writes at most as many bytes as the length of the source
string.

Fixes: 30061915be (spi: spidev_test: Added input buffer from the terminal)

4253168663 spi: st-ssc4: Fix misuse of devm_gpio_request/devm_gpio_free APIs
devm_* API is supposed to be used only in probe function call.
The resource is allocated at 'probe' and free automatically at 'remove'.
Usage of devm_* functions outside probe sometimes leads to resource leak.
Thus avoid using devm_* APIs in .setup/.cleanup callbacks.

if this happens. Additionally, ensure that negative arguments trigger

fe158a17c1 ARM: orion: simplify orion_ge00_switch_init
One of the last users of NO_IRQ on ARM is the switch initialization
code on orion5x, which sometimes passes a GPIO based IRQ number.

However, the driver doesn't actually use this number, and according
to Andrew Lunn never will do it for non-DT based machines, so
we can simply drop the irq argument.

Simplifying it further, we can also drop the static platform_device
and instead call platform_device_register_data(), which in turn
lets us mark the platform_data structures as __initdata and slightly
reduce the memory consumption.

de75abbe01 arm/xen: fix SMP guests boot
Commit 88e957d6e4 ("xen: introduce xen_vcpu_id mapping") broke SMP
ARM guests on Xen. When FIFO-based event channels are in use (this is
the default), evtchn_fifo_alloc_control_block() is called on
CPU_UP_PREPARE event and this happens before we set up xen_vcpu_id
mapping in xen_starting_cpu. Temporary fix the issue by setting direct
Linux CPU id <-> Xen vCPU id mapping for all possible CPUs at boot. We
don't currently support kexec/kdump on Xen/ARM so these ids always
match.

In future, we have several ways to solve the issue, e.g.:

- Eliminate all hypercalls from CPU_UP_PREPARE, do them from the
  starting CPU. This can probably be done for both x86 and ARM and, if
  done, will allow us to get Xen's idea of vCPU id from CPUID/MPIDR on
  the starting CPU directly, no messing with ACPI/device tree
  required.

- Save vCPU id information from ACPI/device tree on ARM and use it to
  initialize xen_vcpu_id mapping. This is the same trick we currently
  do on x86.

d4c77c0532 dmaengine: omap-dma: Correct type2 descriptor's member types
The type of CDEI, CSEI, CDFI and CSFI is signed.
This did not caused issue so far as we only use unsigned values.

6cfeaf5125 cpu/hotplug: Include linux/types.h in linux/cpuhotplug.h
The linux/cpuhotplug.h header makes use of the bool type, but wasn't
including linux/types.h to ensure that type has been defined. Fix this
by including linux/types.h in preparation for including
linux/cpuhotplug.h in a file that doesn't do so already.

ecb3f394c5 genirq: Expose interrupt information through sysfs
Information about interrupts is exposed via /proc/interrupts, but the
format of that file has changed over kernel versions and differs across
architectures. It also has varying column numbers depending on hardware.

That all makes it hard for tools to parse.

To solve this, expose the information through sysfs so each irq attribute
is in a separate file in a consistent, machine parsable way.

This feature is only available when both CONFIG_SPARSE_IRQ and
CONFIG_SYSFS are enabled.

Examples:
  /sys/kernel/irq/18/actions:	i801_smbus,ehci_hcd:usb1,uhci_hcd:usb7
  /sys/kernel/irq/18/chip_name:	IR-IO-APIC
  /sys/kernel/irq/18/hwirq:		18
  /sys/kernel/irq/18/name:		fasteoi
  /sys/kernel/irq/18/per_cpu_count:	0,0
  /sys/kernel/irq/18/type:		level

  /sys/kernel/irq/25/actions:	ahci0
  /sys/kernel/irq/25/chip_name:	IR-PCI-MSI
  /sys/kernel/irq/25/hwirq:		512000
  /sys/kernel/irq/25/name:		edge
  /sys/kernel/irq/25/per_cpu_count:	29036,0
  /sys/kernel/irq/25/type:		edge

  	and changelog ]

aa570be6de dmaengine: NO_IRQ removal from powerpc-only drivers
We'd like to eventually remove NO_IRQ on powerpc, so remove usages of it
from powerpc-only drivers.
