Pull sound updates from Takashi Iwai:
"There have been major modernization with the standard bus: in ALSA
sequencer core and HD-audio. Also, HD-audio receives the regmap
support replacing the in-house cache register cache code. These
changes shouldn't impact the existing behavior, but rather
refactoring.
In addition, HD-audio got the code split to a core library part and
the "legacy" driver parts. This is a preliminary work for adapting
the upcoming ASoC HD-audio driver, and the whole transition is still
work in progress, likely finished in 4.1.
Along with them, there are many updates in ASoC area as usual, too:
lots of cleanups, Intel code shuffling, etc.
Here are some highlights:
ALSA core:
- PCM: the audio timestamp / wallclock enhancement
- PCM: fixes in DPCM management
- Fixes / cleanups of user-space control element management
- Sequencer: modernization using the standard bus
HD-audio:
- Modernization using the standard bus
- Regmap support
- Use standard runtime PM for codec power saving
- Widget-path based power-saving for IDT, VIA and Realtek codecs
- Reorganized sysfs entries for each codec object
- More Dell headset support
ASoC:
- Move of jack registration to the card level
- Lots of ASoC cleanups, mainly moving things from the CODEC level to
the card level
- Support for DAPM routes specified by both the machine driver and DT
- Continuing improvements to rcar
- pcm512x enhacements
- Intel platforms updates
- rt5670 updates / fixes
- New platforms / devices: some non-DSP Qualcomm platforms, Google's
Storm platform, Maxmim MAX98925 CODECs and the Ingenic JZ4780 SoC

====================
Intel Wired LAN Driver Updates 2015-04-14
This series contains updates to i40e and i40evf.
Mitch provides a fix for i40e, where VFs were gone and the associated
VSI's had been removed and the rings were not stopped, which in some
circumstances cased memory corruption or DMAR errors. So stop all the
rings associated with each VF before releasing its resources. Also
cleaned up a poorly indented piece of code. Fixes VF link state, where
VF devices were assuming link is up unless told otherwise, which means
that VFs instantiated on a PF with no link, would report the wrong state.
Anjali adds support to add Flow director Sideband rules for a VF from it's
PF. Fixes a recently discovered hardware issue, where after a VFLR
hardware might be indicating to us a reset completion little too early, so
wait another 10 msec for cache to be cleaned up.
Jesse enables the user to dump the internal hardware state for better
debugging by allowing a bash script to acquire information about the
internal hardware state. The data output to the kernel log is collected
by the script and can then be sent to Intel. Also fixed a possible
failure path to allocate memory that was found by smatch. Cleaned up
unused local variables.

Commit 9a2620c877454 ("bnx2x: prevent WARN during driver unload")
switched the napi/busy_lock locking mechanism from spin_lock() into
spin_lock_bh(), breaking inter-operability with netconsole, as netpoll
disables interrupts prior to calling our napi mechanism.
This switches the driver into using atomic assignments instead of the
spinlock mechanisms previously employed.
Based on initial patch from Yuval Mintz & Ariel Elior
I basically added softirq starvation avoidance, and mixture
of atomic operations, plain writes and barriers.
Note this slightly reduces the overhead for this driver when no
busy_poll sockets are in use.

The code sets the expiry value of the timer to a relative value and
starts it with hrtimer_start_expires. That's fine, but that only works
once. The timer is started in relative mode, so the expiry value gets
overwritten with the absolut expiry time (now + expiry).
So once the timer expired, a new call to hrtimer_start_expires results
in an immidiately expired timer, because the expiry value is
already in the past.
Use the proper mechanisms to (re)start the timer in the intended way.

The networking updates from David Miller removed the iocb argument from
sendmsg and recvmsg (in commit 1b784140474e: "net: Remove iocb argument
from sendmsg and recvmsg"), but the crypto code had added new instances
of them.
When I pulled the crypto update, it was a silent semantic mis-merge, and
I overlooked the new warning messages in my test-build. I try to fix
those in the merge itself, but that relies on me noticing. Oh well.

I keep seeing
drivers/cpufreq/intel_pstate.c: In function ‘intel_pstate_init’:
drivers/cpufreq/intel_pstate.c:1187:26: warning: initialization from incompatible pointer type
struct cpuinfo_x86 *c = &boot_cpu_data;
when doing randconfig builds.
This is caused by the fact that when !CONFIG_SMP, asm/processor.h
defines cpu_info to boot_cpu_data and the local variable
struct cpu_defaults *cpu_info
overshadows it leading to this unfortunate assignment in the
preprocessed source:
struct cpu_defaults *boot_cpu_data;
struct cpuinfo_x86 *c = &boot_cpu_data;
Rename the local variable and use static_cpu_has_safe() which alleviates
the need for defining a local cpuinfo_x86 pointer.

Commit dc6c9a35b66b5 ("mm: account pmd page tables to the process")
added a counter that is incremented whenever a PMD is allocated and
decremented whenever a PMD is freed. For hugepages on PPC, common code
is used to allocated PMDs, but arch-specific code is used to free PMDs.
This results in kernel output such as "BUG: non-zero nr_pmds on freeing
mm: 1" when using hugepages.
Update the PPC hugepage PMD freeing code to decrement the count, just
as the above commit did for free_pmd_range().

If CONFIG_ARCH_DMA_ADDR_T_64BIT enabled for x86 systems and physical
memory is more than 4GB, dma_map_page may return a valid memory
address which greater than 0xffffffff. As a result, the mlx5 device page
allocator RB tree will be initialized with valid addresses greater than
0xfffffff.
However, (addr & PAGE_MASK) set the high four bytes to zeros. So, it's
impossible for the function, free_4k, to release the pages whose
addresses greater than 4GB. Memory leaks. And mlx5_ib module can't
release the pages when user try to remove the module, as a result,
system hang.

In some rare cases, IO operations may be not aligned to page
boundaries. This prevents iser from performing fast memory
registration. In order to overcome that iser uses a bounce
buffer to carry the transaction. We basically allocate a buffer
in the size of the transaction and perform a copy.
The buffer allocation using kmalloc is too restrictive since it
requires higher order (atomic) allocations for large transactions
(which may result in memory exhaustion fairly fast for some workloads).
We rewrite the bounce buffer code path to allocate scattered pages
and perform a copy between the transaction sg and the bounce sg.

and pass the relevant data_buf to bounce buffer routine.

This code was added before we had protection data length
calculation (in iser_send_command), so we needed to calc
the sg data length from the sg itself. This is not needed
anymore.

This length miss-calculation may cause a silent data corruption
in the DIX case and cause the device to reference unmapped area.

In case the user unloaded ib_iser while ep_connect is in
progress, we need to destroy the endpoint although ep_disconnect
wasn't invoked (we detect this by the iser conn state != DOWN).
However, if we got an REJECTED/UNREACHABLE CM event we move the
connection state to DOWN which will prevent us from destroying
the endpoint in the module unload stage. Fix this by setting the
connection state to TERMINATING in iser_conn_error so we can still
destroy the endpoint at unload stage.

The driver already defined the pr_format, it just hadn't
been converted to use pr_info, pr_warn, and pr_err instead
of the equivalent printks. Convert so that messages from
the driver are now properly tagged with their driver name
and can be more easily debugged.
In addition, a number of these printk's were not newline
terminated, so fix that at the same time.

Hello,
When an application using XRCs abruptly terminates, the mmaped pages
of the CQ buffers are leaked.
This comes from the fact that when resources are released in
ib_uverbs_cleanup_ucontext(), we fail to release the CQs because their
refcount is not 0.
When creating an XRC SRQ, we increment the associated CQ refcount.
This refcount is only decremented when the SRQ is released.
Therefore we need to release the SRQs prior to the CQs to make sure
that all references to the CQs are gone before trying to release these.

The current code decreases from the mss size (which is the gso_size
from the kernel skb) the size of the packet headers.
It shouldn't do that because the mss that comes from the stack
(e.g IPoIB) includes only the tcp payload without the headers.
The result is indication to the HW that each packet that the HW sends
is smaller than what it could be, and too many packets will be sent
for big messages.
An easy way to demonstrate one more aspect of the problem is by
configuring the ipoib mtu to be less than 2*hlen (2*56) and then
run app sending big TCP messages. This will tell the HW to send packets
with giant (negative value which under unsigned arithmetics becomes
a huge positive one) length and the QP moves to SQE state.

Whenever there is no path->ah to the destination, keep only defined
number of skb's. Otherwise there are cases that the driver can keep
infinite list of skb's.
For example, when one device want to send unicast arp to the destination,
and from some reason the SM doesn't respond, the driver currently keeps
all the skb's. If that unicast arp traffic stopped, all these skb's
are kept by the path object till the interface is down.

As the result of a completion error the QP can moved to SQE state by
the hardware. Since it's not the Error state, there are no flushes
and hence the driver doesn't know about that.
The fix creates a task that after completion with error which is not a
flush tracks the QP state and if it is in SQE state moves it back to RTS.

Update the cached broadcast record in the priv object after every new
join of this broadcast domain group.
These values are needed for the port configuration (MTU size) and to
all the new multicast (non-broadcast) join requests initial parameters.
For example, SM starts with 2K MTU for all the fabric, and after that it
restarts (or handover to new SM) with new port configuration of 4K MTU.
Without using the new values, the driver will keep its old configuration
of 2K and will not apply the new configuration of 4K.
