The MMC host driver should not select the pmic driver, since that
may have other dependencies, notably i2c in this case. It's not
clear what the exact requirement of the driver is, but to preserve
the behavior, this patch changes the 'select' into 'depends on',
meaning you now have to turn on TPS65010 explicitly and then
MMC_OMAP.
Found during randconfig build testing.

The sdhci core was refactored recently and some of those
refactorings required changes in every sdhci platform driver.
Those updates happened around the same time as when the msm
driver was merged so the refactorings missed the msm driver.
Hook in the basic library functions so that we can boot apq8074
dragonboards again instead of crashing when we try to jump to
NULL function pointers.

Commit dd34c37aa3e (gpio: of: Allow -gpio suffix for property names)
added parsing for both -gpio and -gpios suffix but also changed
the handling for deferred probe unintentionally. Because of the
looping the second name will now return -ENOENT instead of
-EPROBE_DEFER. Fix the issue by breaking out of the loop if
-EPROBE_DEFER is encountered.

Fixes:ee45fd92c739
("sfc: Use TX PIO for sufficiently small packets")
The linux net driver uses memcpy_toio() in order to copy into
the PIO buffers.
Even on a 64bit machine this causes 32bit accesses to a write-
combined memory region.
There are hardware limitations that mean that only 64bit
naturally aligned accesses are safe in all cases.
Due to being write-combined memory region two 32bit accesses
may be coalesced to form a 64bit non 64bit aligned access.
Solution was to open-code the memory copy routines using pointers
and to only enable PIO for x86_64 machines.
Not tested on platforms other than x86_64 because this patch
disables the PIO feature on other platforms.
Compile-tested on x86 to ensure that works.
The WARN_ON_ONCE() code in the previous version of this patch
has been moved into the internal sfc debug driver as the
assertion was unnecessary in the upstream kernel code.
This bug fix applies to v3.13 and v3.14 stable branches.

The “affinity hint” mechanism is used by the user space
daemon, irqbalancer, to indicate a preferred CPU mask for irqs.
Irqbalancer can use this hint to balance the irqs between the
cpus indicated by the mask.
We wish the HCA to preferentially map the IRQs it uses to numa cores
close to it. To accomplish this, we use cpumask_set_cpu_local_first(), that
sets the affinity hint according the following policy:
First it maps IRQs to “close” numa cores. If these are exhausted, the
remaining IRQs are mapped to “far” numa cores.

Upon shutdown, the pwm-backlight driver will now power off the
backlight. It also uses the new descriptor-based GPIO API for more
concise GPIO handling.
A large chunk of these changes also converts platforms to use the
lookup mechanism rather than relying on the global number space to
reference PWM devices. This is largely in preparation for more

DM thinp already checks whether the discard_granularity of the data
device is a factor of the thin-pool block size. But when using the
dm-thin-pool's discard passdown support, DM thinp was not selecting the
max of the underlying data device's discard_granularity and the
thin-pool's block size.
Update set_discard_limits() to set discard_granularity to the max of
these values. This enables blkdev_issue_discard() to properly align the
discards that are sent to the DM thin device on a full block boundary.
As such each discard will now cover an entire DM thin-pool block and the
block will be reclaimed.

Jeff Kirsher says:
====================
Intel Wired LAN Driver Updates 2014-06-11
This series contains updates to igb, i40e and i40evf.
Todd makes a change to igb to un-hide invariant returns by getting rid of
the E1000_SUCCESS define and converting those returns to return 0.
Jacob separates the hardware logic from the set function, so that we can
re-use it during a ptp_reset in igb. This enables the reset to return
functionality to the last know timestamp mode, rather than resetting the
value.
Ashish implements context flags for headwb and headwb_addr so that we
do not have to keep them always enabled.
Shannon updates the admin queue API for the new firmware, which adds
set_pf_content, nvm_config_read/write, replaces set_phy_reset with
set_phy_debug and removes nvm_read/write_reg_se. Cleans up the driver
to use the stored base_queue value since there is no need to read the
PCI register for the PF's base queue on every single transmit queue
enable and disable as we already have the value stored from reading
the capability features at startup.
Anjali changes the notion of source and destination for FD_SB in ethtool
to align i40e with other drivers. Adds flow director statistics to
the PF stats. Fixes a bug in ethtool for flow director drop packet
filter where the drop action comes down as a ring_cookie value, so allow
it as a special value that can be used to configure destination control.
Mitch fixes the i40evf to keep the driver from going down when it is
already in a down state. This prevents a CPU soft lock in napi_disable().
Also change the i40evf to check the admin queue error bits since the
firmware can indicate any admin queue error states to the driver via
some bits in the length registers.
Neerav separates out the DCB capability and enabled flags because currently
if the firmware reports DCB capability the driver enables
I40E_FLAG_DCB_ENABLED flag. When this flag is enabled the driver inserts
a tag when transmitting a packet from the port even if there are no DCB
traffic classes configured at the port. So by adding the additional flag,
I40E_FLAG_DCB_CAPABLE, that will be set when the DCB capability is present
and the existing enabled flag will only be set if there are more than one
traffic classes configured at the port.
Greg fixes the i40e driver to not automatically accept tagged packets by
default so that the system must request a VLAN tag packet filter to get
packets with that tag. Greg also converts i40e to use the in-kernel
ether_addr_copy() instead of mempcy().
Jesse removes the FTYPE field from the receive descriptor to match the
hardware implementation.

When an initiator sends an allocation length bigger than what its
command consumes, the target should only return the actual response data
and set the residual length to the unused part of the allocation length.
Add a helper function that command handlers (INQUIRY, READ CAPACITY,
etc) can use to do this correctly, and use this code to get the correct
residual for commands that don't use the full initiator allocation in the
handlers for READ CAPACITY, READ CAPACITY(16), INQUIRY, MODE SENSE and
REPORT LUNS.
This addresses a handful of failures as reported by Christophe with

After relatively recent changes in the ACPI-based PCI hotplug
(ACPIPHP) code, the acpiphp_check_host_bridge() executed for PCI
host bridges via acpi_pci_root_scan_dependent() doesn't do anything
useful, because those bridges do not have hotplug contexts. That
happens by mistake, so fix it by making acpiphp_enumerate_slots()
add hotplug contexts to PCI host bridges too and modify
acpiphp_remove_slots() to drop those contexts for host bridges
as appropriate.

A similar check is performed at the end of sbc_parse_cdb() and is now
enforced if the SYNCHRONIZE CACHE command's backend supports
->execute_sync_cache().
(Add check_lba goto to avoid *_max_sectors checks - nab)

In case the transport is iser we should not include the
iscsi target info in the sendtargets text response pdu.
This causes sendtargets response to include the target
info twice.
Modify iscsit_build_sendtargets_response to filter
transport types that don't match.

In case the discovery session is carried over iser, we can't
access the assumed network portal since the default portal is
used. In this case we don't really need to allocate the fastreg
pool, just prepare to the text pdu that will follow.

free_msi_irqs() is leaking memory, since list_for_each_entry(entry,
&dev->msi_list, list) {...} is never executed, because dev->msi_list is
made empty by the loop just above this one.
Fix it by relying on zero termination of attribute array like
populate_msi_sysfs() does.

No need to read the PCI register for the PF's base queue on every single Tx
queue enable and disable as we already have the value stored from reading
the capability features at startup.

A drop action comes down as a ring_cookie value, so allow it as
a special value that can be used to configure destination control.
Also fix the output to filter read command accordingly.
