I assume that we may have both: CPUs that may have ability to support multiple
transactions, CPUs that support only one, CPUs that support none (as today), as
well as different devices - transaction capable and not.
So, it seems there is a room for compilers to do their work and for class

Hey Daniel,
Here's the sched_clock_register conversion that Stephen did earlier
this summer, as part of extending the generic sched_clock code to
support 64bit counters. Unfortunately the prereqs for this series missed
getting into tip/timers/core for 3.12, so I never sent out this pull
request
Just making it more obvious 'err' refers to the status of the in flight
request (aka saved_areq) and not the new async request we might start.

Races between host->areq being NULL or not are resulting in mmcqd
hung_task panics. Like this one:

this message.
<6>[ 240.501223] mmcqd/1
mmc_start_req() only handles *asynchronous* requests and is easily
confused with mmc_start_request and __mmc_start_req() (both of which
only handle synchronous requests). Renaming should hopefully make
it clearer this function is used to harvest completions and start
new requests.

This is an intermediate step to fixing the locking around the
access to host->areq. Reduce the number of "if (saved_areq) vs

Hexagon does not have a prom.h header, so it is probably broken with
CONFIG_OF enabled. In any case, remove unnecessary prom.h include in
preparation to make prom.h optional.

Once prom.h is no longer implicitly included, we need to include setup.h

Huh? HSW has MOVBE so we won't #UD on it and MOVBE

In order to enable lockdep on seqcount/seqlock structures, we
must explicitly initialize any locks.
The u64_stats_sync structure, uses a seqcount, and thus we need
to introduce a u64_stats_init() function and use it to initialize
the structure.
This unfortunately adds a lot of fairly trivial init
While enabling lockdep on seqlocks, I ran accross the warning below
caused by the ipv6 stats being updated in both irq and non-irq context.
This is a novice attempt to correct the issue, and with this patch
the warning goes away. Any better solutions would be appreciated!

After adding lockdep support to seqlock/seqcount structures,
I started seeing the following warning:
[1.070907] ==
[1.072015] [ INFO: SOFTIRQ-safe -> SOFTIRQ-unsafe lock order detected ]
[1.073181] 3.11.0+ #67 Not tainted

Currently seqlocks and seqcounts don't support lockdep.
After running across a seqcount related deadlock in the timekeeping
code, I used a less-refined and more focused variant of this patch
to narrow down the cause of the issue.
This is a first-pass attempt to properly enable lockdep functionali
I wanted to send this out again for feedback.
This patch series enables lockdep for seqcount/seqlock structures,
as well as provides the required cleanups to explicitly initialize
the seqcount structures on u64_stat_sync users.
In addition the last two patches in this provide naive fixes to
