The dwc3 wrapper driver should not be fiddling with the core interrupts.
Disabling the core interrupts in prepare stops xhci from proper operation.
So remove disable/enable of core interrupts from prepare/complete.

....
The reason is that the SATA controller has no working clock at this
point, and thus ahci_enable_ahci() fails to enable the controller. In
case that there is no SATA disk attached, the imx_sata_disable() gets
called in ahci_imx_error_handler(), and both sata_clk and sata_ref_clk
will be disabled there. Because all the imx_sata_enable() calls
afterward will return immediately due to imxpriv->no_device check, the
SATA controller working clock sata_clk will never get any chance to be
enabled again.
This is a regression caused by commit 90870d79d4f2 (ahci-imx: Port to
library-ised ahci_platform). Before the commit, only sata_ref_clk is
managed by the driver in enable/disable function. But after the commit,
all the clocks are enabled/disabled in a row by ahci platform helpers
ahci_platform_enable[disable]_clks. Since ahb_clk is a bus clock which
does not have gate at all, and i.MX low-power hardware module already
manages sata_clk across suspend/resume cycle, the only clock that needs
to be managed by software is sata_ref_clk.
So instead of using ahci_platform_enable[disable]_clks to manage all
the clocks in a row from imx_sata_enable[disable], we should manage
only sata_ref_clk in there.

In ISOC transfers, when free_slot points to the last TRB (i.e. Link
TRB), and all queued requests meet Missed Interval Isoc error, busy_slot
points to trb0.
busy_slot->trb0
trb1
...
free_slot->trb31(Link TRB)
After end transfer and receiving the XferNotReady event, trb_left is
caculated as 1 which is wrong, and no TRB will be primed to the
endpoint.
The root cause is free_slot is not increased the same way as busy_slot.
When busy_slot is increased by one, it checks if points to a link TRB
after increasement, but free_slot checks it before increasement.
free_slot should behave the same as busy_slot to make the trb_left
caculation correct.

When setting the rate of a clock, by default the clock framework will
change the parent of the clock to the most suitable one in
__clk_mux_determine_rate() (most suitable by looking at the clock rate).
This is a rather dangerous default, and causes problems on AM43x when
using display and ethernet. There are multiple ways to select the clock
muxes on AM43x, and some of those clock paths have the same source
clocks for display and ethernet. When changing the clock rate for the
display subsystem, the clock framework decides to change the display mux
from the dedicated display PLL to a shared PLL which is used by the
ethernet, and then changes the rate of the shared PLL, breaking the
ethernet.
As I don't think there ever is a case where we want the clock framework
to automatically change the parent clock of a clock mux, this patch sets
the CLK_SET_RATE_NO_REPARENT for all ti,mux-clocks.

GCC 4.6.4 spits out the following warning when building perf_event_v7.c:

arch/arm/kernel/perf_event_v7.c:1927:6: warning: 'bit' may be used uninitialized in this function
While upgrading the version of gcc may solve this, the code can also be
organised to be more efficient by not carrying more local variables than
is necessary across the armv7pmu_get_event_idx function call. If we set
'bit' to -1 (which is invalid for clear_bit) we can use that as an
indication whether we need to clear a bit after this function.

A number of configurations spit out warnings similar to:

warning: (SOC_IMX6 && SOC_VF610 && ARCH_OMAP4) selects PL310_ERRATA_727915 which has unmet direct dependencies (CACHE_L2X0)
Clean up the dependencies here:
* PL310 symbols should only be selected when CACHE_L2X0 is enabled.
* Since the cache-l2x0 code detects PL310 presence at runtime, and we will
eventually get rid of CACHE_PL310, surround these errata options with an
if CACHE_L2X0 conditional rather than repeating the dependency against
each.

So from just a quick look we seem to have enough information to
accurately figure out whether a given gem bo is used as a frontbuffer
and where exactly: We have obj->pin_count as a first check with no
false negatives and only negligible false positives. And then we can
just walk the modeset objects and figure out where exactly a buffer is
used as scanout.
Except that we can't due to locking order: If we already hold
dev->struct_mutex we can't acquire any modeset locks, so could
potential chase freed pointers and other evil stuff.
So we need something else. For that introduce a new set of bits
obj->frontbuffer_bits to track where a buffer object is used. That we
can then chase without grabbing any modeset locks.
Of course the consumers of this (DRRS, PSR, FBC, ...) still need to be
able to do their magic both when called from modeset and from gem
code. But that can be easily achieved by adding locks for these
specific subsystems which always nest within either kms or gem
locking.
This patch just adds the relevant update code to all places.
Note that if we ever support multi-planar scanout targets then we need
one frontbuffer tracking bit per attachment point that we expose to
userspace.
v2:
- Fix more oopsen. Oops.
- WARN if we leak obj->frontbuffer_bits when freeing a gem buffer. Fix
the bugs this brought to light.
- s/update_frontbuffer_bits/update_fb_bits/. More consistent with the
fb tracking functions (fb for gem object, frontbuffer for raw bits).
And the function name was way too long.
v3: Size obj->frontbuffer_bits correctly so that all pipes fit in.
v4: Don't update fb bits in set_base on failure. Noticed by Chris.
v5: s/i915_gem_update_fb_bits/i915_gem_track_fb/ Also remove a few
local enum pipe variables which are now no longer needed to make the
function arguments no drop over the 80 char limit.

It doesn't make sense to never again schedule the work, since by the
time we might want to re-enable psr the world might have changed and
we can do it again.
The only exception is when we shut down the pipe, but that's an
entirely different thing and needs to be handled in psr_disable.
Note that later patch will again split psr_exit into psr_invalidate
and psr_flush. But the split is different and this simplification
helps with the transition.
v2: Improve the commit message a bit.

We have _enable/_disable interfaces now for the modeset sequence and
intel_edp_psr_exit for workarounds.
The callsites in intel_display.c are all redundant with the modeset
sequence enable/disable calls in intel_ddi.c. The one in
intel_sprite.c is real and needs to be switched to psr_exit.
If this breaks anything then we need to augment the enable/disable
functions accordingly.

It's not needed and further more will get in the way of a sane
locking scheme - psr_exit _can't_ take modeset locks due to lock
inversion, and at least once dp mst hits the connector list
is no longer static.
But since we track all state in dev_priv->psr there is no need
at all.

The acquire ctx will typically be declared on the stack, which means we

was triggering WARN_ON()s because 'contended' had garbage value.

sysctl handler proc_sctp_do_hmac_alg(), proc_sctp_do_rto_min() and
proc_sctp_do_rto_max() do not properly reflect some error cases
when writing values via sysctl from internal proc functions such
as proc_dointvec() and proc_dostring().
In all these cases we pass the test for write != 0 and partially
do additional work just to notice that additional sanity checks
fail and we return with hard-coded -EINVAL while proc_do*
functions might also return different errors. So fix this up by
simply testing a successful return of proc_do* right after
calling it.
This also allows to propagate its return value onwards to the user.
While touching this, also fix up some minor style issues.

====================
netfilter fixes for net
The following patchset contains netfilter updates for your net tree,
they are:
1) Fix refcount leak when dumping the dying/unconfirmed conntrack lists,
from Florian Westphal.
2) Fix crash in NAT when removing a netnamespace, also from Florian.
3) Fix a crash in IPVS when trying to remove an estimator out of the
sysctl scope, from Julian Anastasov.
4) Add zone attribute to the routing to calculate the message size in
ctnetlink events, from Ken-ichirou MATSUZAWA.
5) Another fix for the dying/unconfirmed list which was preventing to
dump more than one memory page of entries (~17 entries in x86_64).
6) Fix missing RCU-safe list insertion in the rule replacement code
in nf_tables.
7) Since the new transaction infrastructure is in place, we have to
upgrade the chain use counter from u16 to u32 to avoid overflow
after more than 2^16 rules are added.
8) Fix refcount leak when replacing rule in nf_tables. This problem
was also introduced in new transaction.
9) Call the ->destroy() callback when releasing nft-xt rules to fix
module refcount leaks.
10) Set the family in the netlink messages that contain set elements
in nf_tables to make it consistent with other object types.
11) Don't dump NAT port information if it is unset in nft_nat.
12) Update the MAINTAINERS file, I have merged the ebtables entry
into netfilter. While at it, also removed the netfilter users
mailing list, the development list should be enough.

With commit aed3f9d498b ("staging: comedi: addi_apci_1564:
absorb apci1564_reset()"), the apci 1564 driver has gained
a dependency on the addi watchdog module, which is not reflected
correctly in Kconfig, and that can lead to link errors
when the watchdog is disabled.
This adds an explicit 'select', like it is done in the other
addi apci drivers that need it.

Commit bd0fa9bb455d introduced a failure path to cpufreq_update_policy() if
cpufreq_driver->get(cpu) returns NULL. However, it jumps to the 'no_policy'
label, which exits without unlocking any of the locks the function acquired
earlier. This causes later calls into cpufreq to hang.
Fix this by creating a new 'unlock' label and jumping to that instead.

drm/i915: Track which ring a context ran on
Previously we dropped the association of a context to a ring. It is
however very important to know which ring a context ran on (we could
have reused the other member, but I was nitpicky).
This is very important when we switch address spaces, which unlike
context objects, do change per ring.
As an example, if we have:
RCS BCS
ctx A
ctx A
ctx B
ctx B
Without tracking the last ring B ran on, we wouldn't know to switch the
address space on BCS in the last row.
But this is not really true, because we are already checking to != from (with
"from" being = ring->last_context) and that should be enough to make sure we
switch to the right address space.
We would have a problem if we switched the context object for every ring (since
then we would fail to do it in some situations) but we only switch it for the
render ring, so we don't care.
