If the DMAs are not being quiesced properly, it may lead to
stability issues, so the recommendation is to wait till DMAs are
stopped.
After setting the stop bit of RIRB/CORB DMA, we should wait for
stop bit to be set.

M-Audio Profire 610 has an unexpected value in version field of its config
ROM, thus ALSA dice driver is not assigned to the model due to a mismatch
of modalias.
This commit adds an entry to support the model. I expect the entry is
also for Profire 2626.
I note that Profire 610 uses TCD2220 (so-called Dice Jr.), and supports a
part of Extended Application Protocol (EAP).

Payloads of NM entries are not supposed to contain NUL. When we run
into such, only the part prior to the first NUL goes into the
concatenation (i.e. the directory entry name being encoded by a bunch
of NM entries). We do stop when the amount collected so far + the
claimed amount in the current NM entry exceed 254. So far, so good,
but what we return as the total length is the sum of *claimed*
sizes, not the actual amount collected. And that can grow pretty
large - not unlimited, since you'd need to put CE entries in
between to be able to get more than the maximum that could be
contained in one isofs directory entry / continuation chunk and
we are stop once we'd encountered 32 CEs, but you can get about 8Kb
easily. And that's what will be passed to readdir callback as the
name length. 8Kb __copy_to_user() from a buffer allocated by
__get_free_page()

The following commit:
34e2c555f3e1 ("cpufreq: Add mechanism for registering utilization update callbacks")
overlooked the fact that update_load_avg(), where CFS invokes cpufreq
utilization update callbacks, becomes an empty stub on UP kernels.
In consequence, if !CONFIG_SMP, cpufreq governors are never invoked
from CFS and they do not have a chance to evaluate CPU performace
levels and update them often enough.
Needless to say, things don't work as expected then.
Fix the problem by making the !CONFIG_SMP stub of update_load_avg()
invoke cpufreq update callbacks too.

UDP tunnel segmentation code relies on the inner offsets being set for
an UDP tunnel GSO packet, but the inner *_complete() functions will
set the inner offsets only if 'encapsulation' is set before calling
them. Currently, udp_gro_complete() sets 'encapsulation' only after
the inner *_complete() functions are done. This causes the inner
offsets having invalid values after udp_gro_complete() returns, which
in turn will make it impossible to properly segment the packet in case
it needs to be forwarded, which would be visible to the user either as
invalid packets being sent or as packet loss.
This patch fixes this by setting skb's 'encapsulation' in
udp_gro_complete() before calling into the inner complete functions,
and by making each possible UDP tunnel gro_complete() callback set the
inner_mac_header to the beginning of the tunnel payload.

qede requires qed to provide enough resources to accommodate 16 combined
channels, but that upper-bound isn't actually being enforced by it.
Instead, qed inform back to qede how many channels can be opened based on
available resources - but that calculation doesn't really take into account
the resources requested by qede; Instead it considers other FW/HW available
resources.
As a result, if a user would increase the number of channels to more than
16 [e.g., using ethtool] the chip would hang.
This change increments the resources requested by qede to 64 combined
channels instead of 16; This value is an upper bound on the possible
available channels [due to other FW/HW resources].

Pull power management and ACPI fixes from Rafael Wysocki:

sti-cpufreq, ARM64 cpuidle, Operating Performance Points framework,
generic device properties framework) and one fix for a hotplug-related
deadlock in ACPICA that's been there forever, but is nasty enough.
Specifics:
- Fix for a recent regression in the intel_pstate driver causing it
to fail to restore the HWP (HW-managed P-states) configuration of
the boot CPU after suspend-to-RAM (Rafael Wysocki).
- Fix for two recent regressions in the intel_pstate driver, one that
can trigger a divide by zero if the driver is accessed via sysfs
before it manages to take the first sample and one causing it to
fail to update a structure field used in a trace point, so the
information coming from it is less useful (Rafael Wysocki).
- Fix for a problem in the sti-cpufreq driver introduced during the
4.5 cycle that causes it to break CPU PM in multi-platform kernels
by registering cpufreq-dt (which subsequently doesn't work)
unconditionally and preventing the driver that would actually work
from registering (Sudeep Holla).
- Stable-candidate fix for an ARM64 cpuidle issue causing idle state
usage counters to be incorrectly updated for idle states that were
not entered due to errors (James Morse).
- Fix for a recently introduced issue in the OPP (Operating
Performance Points) framework causing it to print bogus error
messages for missing optional regulators (Viresh Kumar).
- Fix for a recently introduced issue in the generic device
properties framework that may cause it to attempt to dereferece and
invalid pointer in some cases (Heikki Krogerus).
- Fix for a deadlock in the ACPICA core that may be triggered by
device (eg Thunderbolt) hotplug (Prarit Bhargava)"

"Fixes for i915, amdgpu/radeon and imx.
The IMX fix is for an autoloading regression found in Fedora. The
radeon fixes, are the same fix to amdgpu/radeon to avoid a hardware
lockup in some circumstances with a bad mode, and a double free bug I
took a few hours chasing down the other morning.
The i915 fixes are across the board, all stable material, and fixing
some hangs and suspend/resume issues, along with a live status
regressions"

I had relied on the kbuild robot for cross build coverage, however it
only builds alpha_defconfig. Switch from HPAGE_SIZE to PMD_SIZE, which
is more widely defined.

With the newly introduced helper functions the skb pulling is hidden
in the checksumming function - and undone before returning to the
caller.
The IGMP and MLD query parsing functions in the bridge still
assumed that the skb is pointing to the beginning of the IGMP/MLD
message while it is now kept at the beginning of the IPv4/6 header.
If there is a querier somewhere else, then this either causes
the multicast snooping to stay disabled even though it could be
enabled. Or, if we have the querier enabled too, then this can
create unnecessary IGMP / MLD query messages on the link.
Fixing this by taking the offset between IP and IGMP/MLD header into
account, too.

These platform drivers are lacking MODULE_ALIAS so module autoloading
doesn't work. Tested on corgi and poodle with kernel 4.4.

Do not load one entry beyond the end of the syscall table when the
syscall number of a traced process equals to __NR_Linux_syscalls.
Similar bug with regular processes was fixed by commit 3bb457af4fa8
("[PARISC] Fix bug when syscall nr is __NR_Linux_syscalls").
This bug was found by strace test suite.
