USB: global suspend and remote wakeup don't mix
The hub driver was recently changed to use "global" suspend for system
suspend transitions on non-SuperSpeed buses. This means that we don't
suspend devices individually by setting the suspend feature on the
upstream hub port; instead devices all go into suspend automatically
when the root hub stops transmitting packets. The idea was to save
time and to avoid certain kinds of wakeup races.
Now it turns out that many hubs are buggy; they don't relay wakeup
requests from a downstream port to their upstream port if the
downstream port's suspend feature is not set (depending on the speed
of the downstream port, whether or not the hub is enabled for remote
wakeup, and possibly other factors).
We can't have hubs dropping wakeup requests. Therefore this patch
goes partway back to the old policy: It sets the suspend feature for a
port if the device attached to that port or any of its descendants is
enabled for wakeup. People will still be able to benefit from the
time savings if they don't care about wakeup and leave it disabled on
all their devices.
In order to accomplish this, the patch adds a new field to the usb_hub
structure: wakeup_enabled_descendants is a count of how many devices
below a suspended hub are enabled for remote wakeup. A corresponding
new subroutine determines the number of wakeup-enabled devices at or
below an arbitrary suspended USB device.
This should be applied to the 3.10 stable kernel.

boot tested on OMAP5 and compile tested on ARM and x86
with different defconfigs.
Many gadget drivers got a depends on HAS_DMA in order
to prevent build failures on !HAS_DMA architectures.
DWC3 learned how to allow a gadget driver to be modprobed
after an unsuccessful modprobe of another gadget driver. It
also got a fix to a wrong bit mask in dwc3_event_type, and
learns to return proper error codes from failed usb3_phy
initialization.
RNDIS function driver can now be built with configfs.
at91_udc now knows that we need to prepare the clock
before enabling it.
renesas_usbhs now lets gadget drivers be modprobed
multiple times.
phy-omap-usb3 got a fix for the DPLL settings.
mv_u3d_core now passes the correct cookie to free_irq().
fotg210-udc got Section mismatch fixes.

Now, this uses SLUB pretty much unmodified, but as it is the -rt kernel
with CONFIG_PREEMPT_RT set, spinlocks are mutexes, although they do
disable migration. But the SLUB code is relatively lockless, and the
spin_locks there are raw_spin_locks (not converted to mutexes), thus I
believe this bug can happen in mainline without -rt features. The -rt
patch is just good at triggering mainline bugs ;-)
Anyway, looking at where this crashed, it seems that the page variable
can be NULL when passed to the node_match() function (which does not
check if it is NULL). When this happens we get the above panic.
As page is only used in slab_alloc() to check if the node matches, if
it's NULL I'm assuming that we can say it doesn't and call the
__slab_alloc() code. Is this a correct assumption?

llist: llist_add() can use llist_add_batch()
llist_add(new, head) can simply use llist_add_batch(new, new, head),
no need to duplicate the code.
This obviously uninlines llist_add() and to me this is a win. But we
can make llist_add_batch() inline if this is desirable, in this case
gcc can notice that new_first == new_last if the caller is llist_add().

llist: fix/simplify llist_add() and llist_add_batch()
1. This is mostly theoretical, but llist_add*() need ACCESS_ONCE().
Otherwise it is not guaranteed that the first cmpxchg() uses the
same value for old_entry and new_last->next.
2. These helpers cache the result of cmpxchg() and read the initial
value of head->first before the main loop. I do not think this
makes sense. In the likely case cmpxchg() succeeds, otherwise
it doesn't hurt to reload head->first.
I think it would be better to simplify the code and simply read
->first before cmpxchg().

ipv6: only static routes qualify for equal cost multipathing
Static routes in this case are non-expiring routes which did not get
configured by autoconf or by icmpv6 redirects.
To make sure we actually get an ecmp route while searching for the first
one in this fib6_node's leafs, also make sure it matches the ecmp route
assumptions.
v2:
a) Removed RTF_EXPIRE check in dst.from chain. The check of RTF_ADDRCONF
already ensures that this route, even if added again without
RTF_EXPIRES (in case of a RA announcement with infinite timeout),
does not cause the rt6i_nsiblings logic to go wrong if a later RA
updates the expiration time later.
v3:
a) Allow RTF_EXPIRES routes to enter the ecmp route set. We have to do so,
because an pmtu event could update the RTF_EXPIRES flag and we would
not count this route, if another route joins this set. We now filter
only for RTF_GATEWAY|RTF_ADDRCONF|RTF_DYNAMIC, which are flags that
don't get changed after rt6_info construction.

The usual straighforward failure to check for dma_mapping_error after a map
operation is completed.
This patch should fix it, the reporter wandered off after filing this bz:
https://bugzilla.redhat.com/show_bug.cgi?id=954170
and I don't have hardware to test, but the fix is pretty straightforward, so I
figured I'd post it for review.

We should not allow hrtimer code to do softirq wakeups while holding scheduler

expired time. We don't much care about those anyway since we have the regular

tick: broadcast: Check broadcast mode on CPU hotplug
On ARM systems the dummy clockevent is registered with the cpu
hotplug notifier chain before any other per-cpu clockevent. This
has the side-effect of causing the dummy clockevent to be
registered first in every hotplug sequence. Because the dummy is
first, we'll try to turn the broadcast source on but the code in
tick_device_uses_broadcast() assumes the broadcast source is in
periodic mode and calls tick_broadcast_start_periodic()
unconditionally.
On boot this isn't a problem because we typically haven't
switched into oneshot mode yet (if at all). During hotplug, if
the broadcast source isn't in periodic mode we'll replace the
broadcast oneshot handler with the broadcast periodic handler and
start emulating oneshot mode when we shouldn't. Due to the way
the broadcast oneshot handler programs the next_event it's
possible for it to contain KTIME_MAX and cause us to hang the
system when the periodic handler tries to program the next tick.
Fix this by using the appropriate function to start the broadcast
source.

Paul was quick to explain that due to preemptible RCU we cannot call
rcu_read_unlock() while holding scheduler (or nested) locks when part
of the read side critical section was preemptible.
Therefore solve it by making the entire RCU read side non-preemptible.
Also pull out the retry from under the non-preempt to play nice with RT.

perf: Remove WARN_ON_ONCE() check in __perf_event_enable() for valid scenario
The '!ctx->is_active' check has a valid scenario, so
there's no need for the warning.
The reason is that there's a time window between the
'ctx->is_active' check in the perf_event_enable() function
and the __perf_event_enable() function having:
- IRQs on
- ctx->lock unlocked
where the task could be killed and 'ctx' deactivated by
perf_event_exit_task(), ending up with the warning below.
So remove the WARN_ON_ONCE() check and add comments to
explain it all.

perf: Clone child context from parent context pmu
Currently when the child context for inherited events is
created, it's based on the pmu object of the first event
of the parent context.
This is wrong for the following scenario:
- HW context having HW and SW event
- HW event got removed (closed)
- SW event stays in HW context as the only event
and its pmu is used to clone the child context
The issue starts when the cpu context object is touched
based on the pmu context object (__get_cpu_context). In
this case the HW context will work with SW cpu context
ending up with following WARN below.
Fixing this by using parent context pmu object to clone
from child context.

Base on cdc_ether, add the mii functions for RTL8152 and RTL8153.

gre: Fix MTU sizing check for gretap tunnels
This change fixes an MTU sizing issue seen with gretap tunnels when non-gso
packets are sent from the interface.
In my case I was able to reproduce the issue by simply sending a ping of
1421 bytes with the gretap interface created on a device with a standard
1500 mtu.
This fix is based on the fact that the tunnel mtu is already adjusted by
dev->hard_header_len so it would make sense that any packets being compared
against that mtu should also be adjusted by hard_header_len and the tunnel
header instead of just the tunnel header.
