ALSA: hda - Fix invalid multi-io creation on VAIO-Z laptops
VAIO-Z laptops need to use the specific DAC for the speaker output
by some unknown reason although the codec itself supports the flexible
connection. So we implemented a workaround by a new flag,
no_primary_hp, for assigning the speaker pin first.
This worked until 3.8 kernel, but it got broken because the driver
learned for a better multi-io pin mapping, and not it can assign two
mic pins for multi-io. Since the multi-io requires to be the primary
output, the hp and two mic pins are assigned in prior to the speaker
in the end.
Although the machine has two mic pins, one of them is used as a noise-
canceling headphone, thus it's no real retaskable mic jack. Thus, at
best, we can disable the multi-io assignment and make the parser
behavior back to the state before the multi-io.
This patch adds again a new flag, no_multi_io, to indicate that the
device has no multi-io capability, and set it in the fixup for
VAIO-Z. The no_multi_io flag itself can be used generically, added
via a helper line, too.

ALSA: hda - Add snd_hda_jack_detect_state() helper function
snd_hda_jack_detect() function returns a boolean value for a jack
plugged in or not, but it also returns always true when the
corresponding pin is phantom (i.e. fixed). This is OK in most cases,
but it makes the generic parser misbehaving about the auto-mute or
auto-mic switching, e.g. when one of headphone pins is a fixed.
Namely, the driver decides whether to mute the speaker or not, just
depending on the headphone plug state: if one of the headphone jacks
is seen as active, then the speaker is muted. Thus this will result
always in the muted speaker output.
So, the problem is the function returns a boolean, after all, although
we need to think of "phantom" jack. Now a new function,
snd_hda_jack_detect_state() is introduced to return these tristates.
The generic parser uses this function for checking the headphone or
mic jack states.
Meanwhile, the behavior of snd_hda_jack_detect() is kept as is, for
keeping compatibility in other driver codes.

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.

of realizing that it modifies its argument and returns a
remainder. The side-effect from this would be bogus numbers

sched: Fix HRTICK
David reported that the HRTICK sched feature was borken; which was enough
motivation for me to finally fix it ;-)
We should not allow hrtimer code to do softirq wakeups while holding scheduler
locks. The hrtimer code only needs this when we accidentally try to program an
expired time. We don't much care about those anyway since we have the regular
tick to fall back to.

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.
