3bd354abe1 Merge tag 'edac_for_3.14' of git://git.kernel.org/pub/scm/linux/kernel/git/bp/bp
Pull EDAC fixes from Borislav Petkov:
 "Fix polling timeout setting through sysfs.

  You're surely wondering why the patches are not based on an rc.  Well,
  Andrew sent you 79040cad3f ("drivers/edac/edac_mc_sysfs.c: poll
  timeout cannot be zero sent you") already (it got in in -rc2) but it
  is not enough as a fix because for one, setting too low polling
  intervals (< 1sec) don't make any sense and cause unnecessary polling
  load on the system.

  Then, even if we set some interval, we explode with

    [ 4143.094342] WARNING: CPU: 1 PID: 0 at kernel/workqueue.c:1393 __queue_work+0x1d7/0x340()

  because the workqueue setup path is used also for the timeout period
  resetting and we're doing INIT_DELAYED_WORK() on an already active
  workqueue.  Which is total bollocks.  So this is taken care of by the
  second patch.

  I've CCed stable for those two"

cb6ef42e51 EDAC: Correct workqueue setup path
We're using edac_mc_workq_setup() both on the init path, when
we load an edac driver and when we change the polling period
(edac_mc_reset_delay_period) through /sys/.../edac_mc_poll_msec.

On that second path we don't need to init the workqueue which has been
initialized already.

Thanks to Tejun for workqueue insights.

When scanning netdevices we need to check a few more conditions and
cases to build the IBoE GID table properly.  For example, under
bonding we must make sure that when a port is down, the bond IP

ddf8bd3491 IB/mlx4: Do IBoE locking earlier when initializing the GID table
Updating the GID table under IBoE requires read/write from/to shared
data structures.  These data structures are protected with the device
iboe lock.  The flows that modify the GID table start from

    1. Initializing the GID table
    2. NETDEV events
    3. INET or INET6 events

This patch makes sure that the flow of initializing the GID table is
consistent with the other two flows w.r.t on what step the lock is taken.

acc4fccf4e IB/mlx4: Make sure GID index 0 is always occupied
Make sure that for Ethernet ports, the port GID table index 0 is always
occupied with a default GID of the relevant IPv6 link-local adderss.

This provides better user experience for legacy applications that don't use
the RDMA CM and were working on index 0 prior to the IP addressing change.

Also, as GIDs are generated from IP addresses of the network devices that
are associated with the port, it's basically possible that the GID table
will be empty if no IP address was assigned.  This doesn't comply with the
IB spec section 4.1.1 "GID usage and properties".

This reverts commit d3c56568f4.

The reverted commit breaks audio through headphone line out on
the Acer TravelMate B113 (Type1Sku0) Notebook, my main work
machine. I don't know much about it but this fixes my problem.
Bisected and tested.

c8123f8c9c block: add cond_resched() to potentially long running ioctl discard loop
When mkfs issues a full device discard and the device only
supports discards of a smallish size, we can loop in
blkdev_issue_discard() for a long time. If preempt isn't enabled,
this can turn into a softlock situation and the kernel will
start complaining.

Add an explicit cond_resched() at the end of the loop to avoid
that.

Pull powerpc updates from Ben Herrenschmidt:
 "Here is some powerpc goodness for -rc2.  Arguably -rc1 material more
  than -rc2 but I was travelling (again !)

  It's mostly bug fixes including regressions, but there are a couple of
  new things that I decided to drop-in.

  One is a straightforward patch from Michael to add a bunch of P8 cache
  events to perf.

  The other one is a patch by myself to add the direct DMA (iommu
  bypass) for PCIe on Power8 for 64-bit capable devices.  This has been
  around for a while, I had lost track of it.  However it's been in our
  internal kernels we use for testing P8 already and it affects only P8
  related code.  Since P8 is still unreleased the risk is pretty much
  nil at this point"

49f5baa510 blk-mq: pair blk_mq_start_request / blk_mq_requeue_request
Make sure we have a proper pairing between starting and requeueing
requests.  Move the dma drain and REQ_END setup into blk_mq_start_request,
and make sure blk_mq_requeue_request properly undoes them, giving us
a pair of function to prepare and unprepare a request without leaving
side effects.

Together this ensures we always clean up properly after
BLK_MQ_RQ_QUEUE_BUSY returns from ->queue_rq.

1e93b8c274 blk-mq: dont assume rq->errors is set when returning an error from ->queue_rq
rq->errors never has been part of the communication protocol between drivers
and the block stack and most drivers will not have initialized it.

Return -EIO to upper layers when the driver returns BLK_MQ_RQ_QUEUE_ERROR
unconditionally.  If a driver want to return a different error it can easily
do so by returning success after calling blk_mq_end_io itself.

8423ae3d7a block: Fix cloning of discard/write same bios
Immutable biovecs changed the way bio segments are treated in such a way that
bio_for_each_segment() cannot now do what we want for discard/write same bios,
since bi_size means something completely different for them.

Fortunately discard and write same bios never have more than a single biovec, so
bio_for_each_segment() is unnecessary and not terribly meaningful for them, but
we still have to special case them in a few places.
