It is perfectly legitimate for a PCI device to have an
PCI_INTERRUPT_PIN value of zero. This happens if the device doesn't
use interrupts, or on PCIe devices, where only MSI/MSI-X are
supported.
Silence the annoying "of_irq_parse_pci() failed with rc=-19" error
messages by moving the printing code into of_irq_parse_pci(), and only
emitting the message for cases where PCI_INTERRUPT_PIN == 0 is not the
cause for an early exit.

The ret pointer passed to regulator_dev_lookup is only filled with a
valid error code if regulator_dev_lookup returned NULL. Currently
regulator_resolve_supply checks this ret value before it checks if a
regulator was returned, this can result in valid regulator lookups being
ignored.

pmem_rw_page() needs to call wmb_pmem() on writes to make sure that the

and pmem_make_request() with this commit:
commit 61031952f4c8 ("arch, x86: pmem api for ensuring durability of
persistent memory updates")
...the pmem_rw_page() path was missed.

Connection last_ping is not being updated when iscsi_send_nopout fails.
Not updating the last_ping will cause firing a timer to a past time
(last_ping + ping_tmo < current_time) which triggers an infinite loop of
iscsi_check_transport_timeouts() and hogs the cpu.
Fix this issue by checking the return value of iscsi_send_nopout.
If it fails set the next_timeout to one second later.

The commit [b67893206fc0: leds:lp55xx: fix firmware loading error]
tries to address the firmware file handling with user helper, but it
sets a wrong Kconfig CONFIG_FW_LOADER_USER_HELPER_FALLBACK. Since the
wrong option was enabled, the system got a regression -- it suffers
from the unexpected long delays for non-present firmware files.
This patch corrects the Kconfig dependency to the right one,
CONFIG_FW_LOADER_USER_HELPER. This doesn't change the fallback
behavior but only enables UMH when needed.

If a mux clock is initialised (by hardware or firmware) with an
invalid parent, its ->get_parent() can return an out of range
index. For example, the generic mux clock attempts to return
-EINVAL, which due to the u8 return type ends up a rather large
number. Using this index with the parent_names[] array results
in an invalid pointer and (usually) a crash in the following
strcmp().
This patch adds a check for the parent index being in range,
ignoring clocks reporting invalid values.

set_irq_flags is ARM specific with custom flags which have genirq
equivalents. Convert drivers to use the genirq interfaces directly, so we
can kill off set_irq_flags. The translation of flags is as follows:
IRQF_VALID -> !IRQ_NOREQUEST
IRQF_PROBE -> !IRQ_NOPROBE
IRQF_NOAUTOEN -> IRQ_NOAUTOEN
For IRQs managed by an irqdomain, the irqdomain core code handles clearing
and setting IRQ_NOREQUEST already, so there is no need to do this in
.map() functions and we can simply remove the set_irq_flags calls. Some
users also modify IRQ_NOPROBE and this has been maintained although it
is not clear that is really needed. There appears to be a great deal of
blind copy and paste of this code.

set_irq_flags is ARM specific with custom flags which have genirq
equivalents. Convert drivers to use the genirq interfaces directly, so we
can kill off set_irq_flags. The translation of flags is as follows:
IRQF_VALID -> !IRQ_NOREQUEST
IRQF_PROBE -> !IRQ_NOPROBE
IRQF_NOAUTOEN -> IRQ_NOAUTOEN
For IRQs managed by an irqdomain, the irqdomain core code handles clearing
and setting IRQ_NOREQUEST already, so there is no need to do this in
.map() functions and we can simply remove the set_irq_flags calls. Some
users also modify IRQ_NOPROBE and this has been maintained although it
is not clear that is really needed. There appears to be a great deal of
blind copy and paste of this code.

Pull crypto fixes from Herbert Xu:
"This fixes the following issues:
- The selftest overreads the IV test vector.
- Fix potential infinite loop in sunxi-ss driver.
- Fix powerpc build failure when VMX is set without VSX"
* git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
crypto: testmgr - don't copy from source IV too much
crypto: sunxi-ss - Fix a possible driver hang with ciphers
crypto: vmx - VMX crypto should depend on CONFIG_VSX

Most interrupt flow handlers do not use the irq argument. Those few
which use it can retrieve the irq number from the irq descriptor.
Remove the argument.
Search and replace was done with coccinelle and some extra helper
scripts around it. Thanks to Julia for her help!

In virtio_ccw_read_vq_conf() the return value of ccw_io_helper()
was not checked.
If the configuration could not be read properly, we'd wrongly assume a
queue size of 0.
Let's propagate any I/O error to virtio_ccw_setup_vq() so it may
properly fail.
