For sequential workload (or request size big workload), get_active_stripe can
find cached stripe. In this case, we always hold device_lock, which exposes a
lot of lock contention for such workload. If stripe count isn't 0, we don't
need hold the lock actually, since we just increase its count. And this is the
hot code path for such workload. Unfortunately we must delete the BUG_ON.

In NUMA machine, prepare_to_wait/finish_wait in make_request exposes a
lot of contention for sequential workload (or big request size
workload). For such workload, each bio includes several stripes. So we
can just do prepare_to_wait/finish_wait once for the whold bio instead
of every stripe. This reduces the lock contention completely for such
workload. Random workload might have the similar lock contention too,
but I didn't see it yet, maybe because my stroage is still not fast
enough.

If md-mod is unloaded while some process is in poll() or select(),
then that process maintains a pointer to md_event_waiters, and when
the try to unlink from that list, they will oops.
The procfs infrastructure ensures that ->poll won't be called after
remove_proc_entry, but doesn't provide a wait_queue_head for us to
use, and the waitqueue code doesn't provide a way to remove all
listeners from a waitqueue.
So we need to:
1/ make sure no further references to md_event_waiters are taken (by
setting md_unloading)
2/ wake up all processes currently waiting, and
3/ wait until all those processes have disconnected from our
wait_queue_head.

When performing a user-request check/repair (MD_RECOVERY_REQUEST is set)
on a raid1, we allocate multiple bios each with their own set of pages.
If the page allocations for one bio fails, we currently do *not* free
the pages allocated for the previous bios, nor do we free the bio itself.
This patch frees all the already-allocate pages, and makes sure that
all the bios are freed as well.
This bug can cause a memory leak which can ultimately OOM a machine.

This was caused by that 'sd->groups == NULL' after building groups, which
was caused by the empty 'sd->span'.
The cpu's domain contained nothing because the cpu was assigned to a wrong
node, due to the following unfortunate sequence of events:
1. The hypervisor sent a topology update to the guest OS, to notify changes
to the cpu-node mapping. However, the update was actually redundant - i.e.,
the "new" mapping was exactly the same as the old one.
2. Due to this, the 'updated_cpus' mask turned out to be empty after exiting
the 'for-loop' in arch_update_cpu_topology().
3. So we ended up calling stop-machine() with an empty cpumask list, which made
stop-machine internally elect cpumask_first(cpu_online_mask), i.e., CPU0 as
the cpu to run the payload (the update_cpu_topology() function).
4. This causes update_cpu_topology() to be run by CPU0. And since 'updates'
is kzalloc()'ed inside arch_update_cpu_topology(), update_cpu_topology()
finds update->cpu as well as update->new_nid to be 0. In other words, we
end up assigning CPU0 (and eventually its siblings) to node 0, incorrectly.
Along with the following wrong updating, it causes the sched-domain rebuild
code to break and crash the system.
Fix this by skipping the topology update in cases where we find that
the topology has not actually changed in reality (ie., spurious updates).

This results in allocating less memory to hold available recoverable range

This patch fixes this issue by allocating mc_recoverable_range buffer based

So discard that - root should be allowed to shoot self in foot.
Still use it in a much less intrusive way to stop the same file being
used as bitmap on two different array, and apply other checks to
ensure the file is at least vaguely usable for bitmap storage
(is regular, is open for write. Support for ->bmap is already checked

Register/unregister tracepoint probes with struct tracepoint pointer
rather than tracepoint name.
This change, which vastly simplifies tracepoint.c, has been proposed by
Steven Rostedt. It also removes 8.8kB (mostly of text) to the vmlinux
size.
From this point on, the tracers need to pass a struct tracepoint pointer
to probe register/unregister. A probe can now only be connected to a
tracepoint that exists. Moreover, tracers are responsible for
unregistering the probe before the module containing its associated
tracepoint is unloaded.

I got a bug report yesterday from Laszlo Ersek in which he states that
his kvm instance fails to suspend. Laszlo bisected it down to this
commit 1cf7e9c68f ("virtio_blk: blk-mq support") where virtio-blk is
converted to use the blk-mq infrastructure.
After digging a bit, it became clear that the issue was with the queue
drain. blk-mq tracks queue usage in a percpu counter, which is
incremented on request alloc and decremented when the request is freed.
The initial hunt was for an inconsistency in blk-mq, but everything
seemed fine. In fact, the counter only returned crazy values when
suspend was in progress.
When a CPU is unplugged, the percpu counters merges that CPU state with
the general state. blk-mq takes care to register a hotcpu notifier with
the appropriate priority, so we know it runs after the percpu counter
notifier. However, the percpu counter notifier only merges the state
when the CPU is fully gone. This leaves a state transition where the
CPU going away is no longer in the online mask, yet it still holds
private values. This means that in this state, percpu_counter_sum()
returns invalid results, and the suspend then hangs waiting for
abs(dead-cpu-value) requests to complete which of course will never
happen.
Fix this by clearing the state earlier, so we never have a case where
the CPU isn't in online mask but still holds private state. This bug
has been there since forever, I guess we don't have a lot of users where
percpu counters needs to be reliable during the suspend cycle.

Page reclaim force-scans / swaps anonymous pages when file cache drops
below the high watermark of a zone in order to prevent what little cache
remains from thrashing.
However, on bigger machines the high watermark value can be quite large
and when the workload is dominated by a static anonymous/shmem set, the
file set might just be a small window of used-once cache. In such
situations, the VM starts swapping heavily when instead it should be
recycling the no longer used cache.
This is a longer-standing problem, but it's more likely to trigger after
commit 81c0a2bb51 ("mm: page_alloc: fair zone allocator policy")
because file pages can no longer accumulate in a single zone and are
dispersed into smaller fractions among the available zones.
To resolve this, do not force scan anon when file pages are low but
instead rely on the scan/rotation ratios to make the right prediction.

This is mostly a few additional fixes from Lars-Peter, a new driver and
cleaning up a git failure with merging the Intel branch (combined with
an xargs failure to pay attention to error codes). The history lists a
bunch of additional commits for the branch but the content of those
commits is actually present already but not recorded in history due to
git failing. Unfortunately xargs is used in the merge script and it
doesn't do a good job of noticing errors from the commands it invokes.

Quite a busy release for ASoC this time, more on janitorial work than
exciting new features but welcome nontheless:
- Lots of cleanups from Takashi for enumerations; the original API for
these was error prone so he's refactored lots of code to use more
modern APIs which avoid issues.
- Elimination of the ASoC level wrappers for I2C and SPI moving us
closer to converting to regmap completely and avoiding some
randconfig hassle.
- Provide both manually and transparently locked DAPM APIs rather than
a mix of the two fixing some concurrency issues.
- Start converting CODEC drivers to use separate bus interface drivers
rather than having them all in one file helping avoid dependency
issues.
- DPCM support for Intel Haswell and Bay Trail platforms.
- Lots of work on improvements for simple-card, DaVinci and the Renesas
rcar drivers.
- New drivers for Analog Devices ADAU1977, TI PCM512x and parts of the
CSR SiRF SoC.

Pull more networking updates from David Miller:
1) If a VXLAN interface is created with no groups, we can crash on
reception of packets. Fix from Mike Rapoport.
2) Missing includes in CPTS driver, from Alexei Starovoitov.
3) Fix string validations in isdnloop driver, from YOSHIFUJI Hideaki
and Dan Carpenter.
4) Missing irq.h include in bnxw2x, enic, and qlcnic drivers. From
Josh Boyer.
5) AF_PACKET transmit doesn't statistically count TX drops, from Daniel
Borkmann.
6) Byte-Queue-Limit enabled drivers aren't handled properly in
AF_PACKET transmit path, also from Daniel Borkmann.
Same problem exists in pktgen, and Daniel fixed it there too.
7) Fix resource leaks in driver probe error paths of new sxgbe driver,
from Francois Romieu.
8) Truesize of SKBs can gradually get more and more corrupted in NAPI
packet recycling path, fix from Eric Dumazet.
9) Fix uniprocessor netfilter build, from Florian Westphal. In the
longer term we should perhaps try to find a way for ARRAY_SIZE() to
work even with zero sized array elements.
10) Fix crash in netfilter conntrack extensions due to mis-estimation of
required extension space. From Andrey Vagin.
11) Since we commit table rule updates before trying to copy the
counters back to userspace (it's the last action we perform), we
really can't signal the user copy with an error as we are beyond the
point from which we can unwind everything. This causes all kinds of
use after free crashes and other mysterious behavior.
From Thomas Graf.
12) Restore previous behvaior of div/mod by zero in BPF filter
processing. From Daniel Borkmann.

Here are some more staging patches for 3.15-rc1. They include a
late-submission of a wireless driver that a bunch of people seem to have
the hardware for now. As it's stand-alone, it should be fine (now
passes the 0-day random build bot tests.) There are also some fixes for
the unisys drivers, as they were causing havoc on a number of different
machines. To resolve all of those issues, we just mark the driver as
BROKEN now, and we can fix it up "properly" over time.

The UEFI Forum included the ACPI spec in its portfolio in October 2013
and will host future spec iterations, following the ACPI v5.0a release.
A UEFI Forum working group named ACPI Specification Working Group (ASWG)
has been established to handle future ACPI developments, any UEFI member
can join the group and contribute to ACPI specification.
So update the ownership and developers for ACPI in Kconfig accordingly,
and add another website link to ACPI specification too.
