amount of memory using an char array.
The new code can be compiled with both gcc and clang.
struct shash_desc contains a flexible array member member ctx declared with
CRYPTO_MINALIGN_ATTR, so sizeof(struct shash_desc) aligns the beginning
of the array declared after struct shash_desc with long long.
No trailing padding is required because it is not a struct type that can
be used in an array.
The CRYPTO_MINALIGN_ATTR is required so that desc is aligned with long long
as would be the case for a struct containing a member with
CRYPTO_MINALIGN_ATTR.
If you want to get to the ctx at the end of the shash_desc as before you can do
so using shash_desc_ctx(shash)

In ib_uverbs_open_qp, the sharable xrc target qp is created as a
"pseudo" qp and added to a list of qp's sharing the same physical
QP. This is done before the "pseudo" qp is assigned a uobject.
There is a race condition here if an async event arrives at the
physical qp. If the event is handled after the pseudo qp is added to
the list, but before it is assigned a uobject, the kernel crashes in
ib_uverbs_qp_event_handler, due to trying to dereference a NULL
uobject pointer.
Note that simply checking for non-NULL is not enough, due to error
flows in ib_uverbs_open_qp. If the failure is after assigning the
uobject, but before the qp has fully been created, we still have a
problem.
Thus, in ib_uverbs_qp_event_handler, we test that the uobject is
present, and also that it is live.

The emu10k1 voice allocator takes voice_lock spinlock. When there is
no empty stream available, it tries to release a voice used by synth,
and calls get_synth_voice. The callback function,
snd_emu10k1_synth_get_voice(), however, also takes the voice_lock,
thus it deadlocks.
The fix is simply removing the voice_lock holds in
snd_emu10k1_synth_get_voice(), as this is always called in the
spinlock context.

Pull do_umount fix from Andy Lutomirski:
"This fix really ought to be safe. Inside a mountns owned by a
non-root user namespace, the namespace root almost always has
MNT_LOCKED set (if it doesn't, then there's a bug, because rootfs
could be exposed). In that case, calling umount on "/" will return
-EINVAL with or without this patch.
Outside a userns, this patch will have no effect. may_mount, required
by umount, already checks
ns_capable(current->nsproxy->mnt_ns->user_ns, CAP_SYS_ADMIN)
so an additional capable(CAP_SYS_ADMIN) check will have no effect.
That leaves anything that calls umount on "/" in a non-root userns
while chrooted. This is the case that is currently broken (it
remounts ro, which shouldn't be allowed) and that my patch changes to
-EPERM. If anything relies on *that*, I'd be surprised"

The main 'md' thread is needed for processing writes, so if it blocks
write requests could be delayed.
Starting a new thread requires some GFP_KERNEL allocations and so can
wait for writes to complete. This can deadlock.
So instead, ask a workqueue to start the sync thread.
There is no particular rush for this to happen, so any work queue
will do.
MD_RECOVERY_RUNNING is used to ensure only one thread is started.

In general we don't allow an array to be stopped if it is in use.
However if the array hasn't really been started yet, then any
apparent use is an anomily, probably due to 'udev' or similar
having a look to see what is there.
This means that if something goes wrong while assembling an array
it cannot reliably be un-assembled - STOP_ARRAY could fail.
There is no value here, so change do_md_stop() to succeed
despite concurrent opens if the array has not yet been
activated. i.e. if ->pers is NULL.

The interesting bits are:
- Quite a bit of work on the tracing front. Uprobes is enabled and
the ftrace code is reworked to get some of the lost performance
back if CONFIG_FTRACE is enabled.
- To improve boot time with CONFIG_DEBIG_PAGEALLOC, support for the
IPTE range facility is added.
- The rwlock code is re-factored to improve writer fairness and to be
able to use the interlocked-access instructions.
- The kernel part for the support of the vector extension is added.
- The device driver to access the CD/DVD on the HMC is added, this

Pull x86 seccomp changes from Ingo Molnar:
"This tree includes x86 seccomp filter speedups and related preparatory
work, which touches core seccomp facilities as well.
The main idea is to split seccomp into two phases, to be able to enter
a simple fast path for syscalls with ptrace side effects.
There's no substantial user-visible (and ABI) effects expected from
this, except a change in how we emit a better audit record for
SECCOMP_RET_TRACE events"
