When the HCA is configured in SRIOV IB mode (that is, at least one of
the ports is IB) and the probe_vf module param isn't specified,
mlx4_init_one() failed because of the following condition:
if (ib_ports && (num_vfs_argc > 1 || probe_vfs_argc > 1)) {
.....
}
The root cause for that is a mistake in the initialization of num_vfs_argc
and probe_vfs_argc. When num_vfs / probe_vf aren't given, their argument
count counterpart should be 0, fix that.

In macvtap device delete and open calls can race and
this causes a list curruption of the vlan queue_list.
The race intself is triggered by the idr accessors
that located the vlan device. The device is stored
into and removed from the idr under both an rtnl and
a mutex. However, when attempting to locate the device
in idr, only a mutex is taken. As a result, once cpu
perfoming a delete may take an rtnl and wait for the mutex,
while another cput doing an open() will take the idr
mutex first to fetch the device pointer and later take
an rtnl to add a queue for the device which may have
just gotten deleted.
With this patch, we now hold the rtnl for the duration
of the macvtap_open() call thus making sure that
open will not race with delete.

Pull networking fixes from David Miller:

fallout from changing SCSI_NETLINK from being used via 'select' to

I applied a set of 5 patches written by Michal Marek, and then I
carefully audited all of the remaining config files, basically:
1) I scanned every arch config file, and if it mentioned CONFIG_INET
or CONFIG_UNIX, I made sure it had CONFIG_NET=y
2) After that, I scanned every arch config file, and if it did not
have CONFIG_NET=y I made sure it did not reference any networking
config options.

make sure to sign extend lower 32 bits in 64-bit register
before calling C helpers from JITed code, otherwise 'int k'
argument of bpf_internal_load_pointer_neg_helper() function
will be added as large unsigned integer, causing packet size
check to trigger and abort the program.
It's worth noting that JITed code for 'A = A op K' will affect
upper 32 bits differently depending whether K is simm13 or not.
Since small constants are sign extended, whereas large constants
are stored in temp register and zero extended.
That is ok and we don't have to pay a penalty of sign extension
for every sethi, since all classic BPF instructions have 32-bit
semantics and we only need to set correct upper bits when
transitioning from JITed code into C.
- though instructions 'A &= 0' and 'A *= 0' are odd, JIT compiler
should not optimize them out

blk-mq uses percpu_ref for its usage counter which tracks the number
of in-flight commands and used to synchronously drain the queue on
freeze. percpu_ref shutdown takes measureable wallclock time as it
involves a sched RCU grace period. This means that draining a blk-mq
takes measureable wallclock time. One would think that this shouldn't
matter as queue shutdown should be a rare event which takes place
asynchronously w.r.t. userland.
Unfortunately, SCSI probing involves synchronously setting up and then
tearing down a lot of request_queues back-to-back for non-existent
LUNs. This means that SCSI probing may take more than ten seconds
when scsi-mq is used.
This will be properly fixed by implementing a mechanism to keep
q->mq_usage_counter in atomic mode till genhd registration; however,
that involves rather big updates to percpu_ref which is difficult to
apply late in the devel cycle (v3.17-rc6 at the moment). As a
stop-gap measure till the proper fix can be implemented in the next
cycle, this patch introduces __percpu_ref_kill_expedited() and makes
blk_mq_freeze_queue() use it. This is heavy-handed but should work
for testing the experimental SCSI blk-mq implementation.

The "by8" implementation introduced in commit 22cddcc7df ("crypto: aes
- AES CTR x86_64 "by8" AVX optimization") is failing crypto tests as it
handles counter block overflows differently. It only accounts the right
most 32 bit as a counter -- not the whole block as all other
implementations do. This makes it fail the cryptomgr test #4 that
specifically tests this corner case.

Add an API, ccp_present(), that checks for the presence of a CCP

should register it's crypto alogorithms.

"This week and last we've been fixing some corner cases related to

This pull request contains:
- Fix from Christoph, avoiding a stack overflow when FUA insertion
would recursive infinitely.
- Fix from David Hildenbrand on races between the timeout handler and
uninitialized requests. Fixes a real issue that virtio_blk has run
into.
- A few fixes from me:
- Ensure that request deadline/timeout is ordered before the
request is marked as started.
- A potential oops on out-of-memory, when we scale the queue
depth of the device and retry.
- A hang fix on requeue from SCSI, where the hardware queue
would be stopped when we attempt to re-run it (and hence
nothing would happen, stalling progress).
- A fix for commit 2da78092, where the cleanup path was moved
to RCU, but a debug might_sleep() was inadvertently left in
the code. This causes warnings for people"

Pull parisc fixes from Helge Deller:
"We avoid using -mfast-indirect-calls for 64bit kernel builds to
prevent building an unbootable kernel due to latest gcc changes.
In the pdc_stable/firmware-access driver we fix a few possible stack
overflows and we now call secure_computing_strict() instead of
secure_computing() which fixes upcoming SECCOMP patches in the
for-next trees"
* 'parisc-3.17-7' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux:
parisc: Only use -mfast-indirect-calls option for 32-bit kernel builds
parisc: pdc_stable.c: Avoid potential stack overflows
parisc: pdc_stable.c: Cleaning up unnecessary use of memset in conjunction with strncpy
parisc: ptrace: use secure_computing_strict()
In spite of what the GCC manual says, the -mfast-indirect-calls has
never been supported in the 64-bit parisc compiler. Indirect calls have
always been done using function descriptors irrespective of the
-mfast-indirect-calls option.
Recently, it was noticed that a function descriptor was always requested
when the -mfast-indirect-calls option was specified. This caused
problems when the option was used in application code and doesn't make
any sense because the whole point of the option is to avoid using a
function descriptor for indirect calls.
Fixing this broke 64-bit kernel builds.
I will fix GCC but for now we need the attached change. This results in
the same kernel code as before.

In the brcmf_count_20mhz_channels function we are looping through a list

Pull networking fixes from David Miller:
1) If the user gives us a msg_namelen of 0, don't try to interpret
anything pointed to by msg_name. From Ani Sinha.
2) Fix some bnx2i/bnx2fc randconfig compilation errors.
The gist of the issue is that we firstly have drivers that span both
SCSI and networking. And at the top of that chain of dependencies
we have things like SCSI_FC_ATTRS and SCSI_NETLINK which are
selected.
But since select is a sledgehammer and ignores dependencies,
everything to select's SCSI_FC_ATTRS and/or SCSI_NETLINK has to also
explicitly select their dependencies and so on and so forth.
Generally speaking 'select' is supposed to only be used for child
nodes, those which have no dependencies of their own. And this
whole chain of dependencies in the scsi layer violates that rather
strongly.
So just make SCSI_NETLINK depend upon it's dependencies, and so on
and so forth for the things selecting it (either directly or
indirectly).
