blk_mq_wait_for_tags() is only able to wait for "normal" tags,
not reserved tags. Pass in which one we should attempt to get
a tag for, so that waiting for reserved tags will work.
Reserved tags are used for internal commands, which are usually
serialized. Hence no waiting generally takes place, but we should
ensure that it actually works if users need that functionality.

If "pcie_bus_config == PCIE_BUS_PERFORMANCE", we don't initialize "smpss",
so we pass a pointer to garbage into pcie_bus_configure_set(), where we
compute "mps" based on the garbage. We then pass the garbage "mps" to
pcie_write_mps(), which ignores it in the PCIE_BUS_PERFORMANCE case.
Coverity isn't smart enough to deduce that we ignore the garbage (it's a
lot to expect from a human, too), so initialize "smpss" to a safe value in
all cases.

Some PCI functions used to be marked __devinit. When CONFIG_HOTPLUG was
not set, these functions were discarded after boot. A few callers of these
__devinit functions were marked __ref to indicate that they could safely
call the __devinit functions even though the callers were not __devinit.
But CONFIG_HOTPLUG and __devinit are now gone, and the need for the __ref
annotations is also gone, so remove them. Relevant historical commits:

While using the sysfs new_id interface, the user can unintentionally feed
incorrect values if the driver static table has a matching entry. This is
possible since only the device and vendor fields are mandatory and the rest
are optional. As a result, store_new_id() will fill in default values that
are then passed on to the driver and can have unintended consequences.
As an example, consider the ixgbe driver and the 82599EB network card:
echo "8086 10fb" > /sys/bus/pci/drivers/ixgbe/new_id
This will pass a pci_device_id with driver_data = 0 to ixgbe_probe(), which
uses that zero to index a table of card operations. The zeroth entry of
the table does *not* correspond to the 82599 operations.
This change returns an error if the user attempts to add a dynid for a
vendor/device combination for which a static entry already exists.
However, if the user intentionally wants a different set of values, she
must provide all the 7 fields and that will be accepted.

- cpufreq_for_each_valid_entry: iterate over each entry that contains
a valid frequency.

Address a regression caused by commit ad332c8a45:
(ACPI / EC: Clear stale EC events on Samsung systems)
After the earlier patch, there was found to be a race condition on some
earlier Samsung systems (N150/N210/N220). The function acpi_ec_clear was
sometimes discarding a new EC event before its GPE was triggered by the
system. In the case of these systems, this meant that the "lid open"
event was not registered on resume if that was the cause of the wake,
leading to problems when attempting to close the lid to suspend again.
After testing on a number of Samsung systems, both those affected by the
previous EC bug and those affected by the race condition, it seemed that
the best course of action was to process rather than discard the events.
On Samsung systems which accumulate stale EC events, there does not seem
to be any adverse side-effects of running the associated _Q methods.
This patch adds an argument to the static function acpi_ec_sync_query so
that it may be used within the acpi_ec_clear loop in place of
acpi_ec_query_unlocked which was used previously.
With thanks to Stefan Biereigel for reporting the issue, and for all the
people who helped test the new patch on affected systems.

To specify multiple elements in this type, added a repeat value.
So new format is:
[be|le]:[s|u]bits/storagebitsXr[>>shift].
Here r is specifying how may times, real/storage bits are repeating.
When X is value is 0 or 1, then repeat value is not used in the format,

This callback is introduced to overcome some limitations of existing

read_raw_multi is similar, both are used to request values from the
device. The current read_raw callback allows only two return values.
The new read_raw_multi allows returning multiple values. Instead of
passing just address of val and val2, it passes length and pointer
to values. Depending on the type and length of passed buffer, iio
client drivers can return multiple values.

When reading from trace_pipe, if tracing is off but nothing was read
it should block. If something is read and tracing is off, then EOF
is returned. If tracing is on and there's nothing to read, it will block.
But because the check of whether tracing is off and something was read
is done after the block on the pipe, it is hit or miss if the EOF is
returned or not leading to inconsistent behavior.

commit 0eba801b64 tried to fix a race
where nat initialisation can happen after ctnetlink-created conntrack
has been created.
However, it causes the nat module(s) to be loaded needlessly on
systems that are not using NAT.
Fortunately, we do not have to create null bindings in that case.
conntracks injected via ctnetlink always have the CONFIRMED bit set,
which prevents addition of the nat extension in nf_nat_ipv4/6_fn().
We only need to make sure that either no nat extension is added
or that we've created both src and dst manips.
