ASoC: Updates for v3.15

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.

ASoC: Updates for v3.15

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.

When using an rbtree cache, there can be allocations the first time a
register is accessed.  This can cause an attempt to schedule while
atomic in the case that the regmap is using a spinlock.  This could be
fixed by either initializing all the registers or using a flat cache.
The register maps for tegra30_ahub and tegra30_i2s are dense and don't
save much from using a tree so convert them to flat.

While testing and documenting the msgrcv() MSG_COPY flag that Stanislav
Kinsbursky added in commit 4a674f34 ("ipc: introduce message queue
copy feature" => kernel 3.8), I discovered a couple of bugs in the
implementation.  The two bugs concern MSG_COPY interactions with other
msgrcv() flags, namely:

 (A) MSG_COPY + MSG_EXCEPT
 (B) MSG_COPY + !IPC_NOWAIT

The bugs are distinct (and the fix for the first one is obvious),
however my fix for both is a single-line patch, which is why I'm
combining them in a single mail, rather than writing two mails+patches.

 ===== (A) MSG_COPY + MSG_EXCEPT =====

With the addition of the MSG_COPY flag, there are now two msgrcv()
flags--MSG_COPY and MSG_EXCEPT--that modify the meaning of the 'msgtyp'
argument in unrelated ways.  Specifying both in the same call is a
logical error that is currently permitted, with the effect that MSG_COPY
has priority and MSG_EXCEPT is ignored.  The call should give an error
if both flags are specified.  The patch below implements that behavior.

 ===== (B) (B) MSG_COPY + !IPC_NOWAIT =====

The test code that was submitted in commit 3a665531 ("selftests: IPC
message queue copy feature test") shows MSG_COPY being used in
conjunction with IPC_NOWAIT.  In other words, if there is no message at
the position 'msgtyp'.  return immediately with the error in ENOMSG.

What was not (fully) tested is the behavior if MSG_COPY is specified
*without* IPC_NOWAIT, and there is an odd behavior.  If the queue
contains less than 'msgtyp' messages, then the call blocks until the
next message is written to the queue.  At that point, the msgrcv() call
returns a copy of the newly added message, regardless of whether that
message is at the ordinal position 'msgtyp'.  This is clearly bogus, and
problematic for applications that might want to make use of the MSG_COPY
flag.

I considered the following possible solutions to this problem:

 (1) Force the call to block until a message *does* appear at the
     position 'msgtyp'.

 (2) If the MSG_COPY flag is specified, the kernel should implicitly add
     IPC_NOWAIT, so that the call fails with ENOMSG for this case.

 (3) If the MSG_COPY flag is specified, but IPC_NOWAIT is not, generate
     an error (probably, EINVAL is the right one).

I do not know if any application would really want to have the
functionality of solution (1), especially since an application can
determine in advance the number of messages in the queue using msgctl()
IPC_STAT.  Obviously, this solution would be the most work to implement.

Solution (2) would have the effect of silently fixing any applications
that tried to employ broken behavior.  However, it would mean that if we
later decided to implement solution (1), then user-space could not
easily detect what the kernel supports (but, since I'm somewhat doubtful
that solution (1) is needed, I'm not sure that this is much of a
problem).

Solution (3) would have the effect of informing broken applications that
they are doing something broken.  The downside is that this would cause
a ABI breakage for any applications that are currently employing the
broken behavior.  However:

a) Those applications are almost certainly not getting the results they
   expect.
b) Possibly, those applications don't even exist, because MSG_COPY is
   currently hidden behind CONFIG_CHECKPOINT_RESTORE.

The upside of solution (3) is that if we later decided to implement
solution (1), user-space could determine what the kernel supports, via
the error return.

In my view, solution (3) is mildly preferable to solution (2), and
solution (1) could still be done later if anyone really cares.  The
patch below implements solution (3).

PS.  For anyone out there still listening, it's the usual story:
documenting an API (and the thinking about, and the testing of the API,
that documentation entails) is the one of the single best ways of
finding bugs in the API, as I've learned from a lot of experience.  Best
to do that documentation before releasing the API.

Pull ACPI and power management fixes from Rafael Wysocki:
 "Three of these are regression fixes, for two recent regressions and
  one introduced during the 3.13 cycle, and the fourth one is a working
  version of the fix that had to be reverted last time.

  Specifics:

   - A recent ACPI resources handling fix overlooked the fact that it
     had to update the ACPI PNP subsystem's resources parsing too and
     caused confusing warning messages to be printed during system
     intialization on some systems (with arguably buggy ACPI tables).
     Fix from Zhang Rui.

   - Moving the early ACPI initialization before timekeeping_init()
     earlier in this cycle broke fast TSC calibration on at least one
     system, so it needs to be done later, but still before
     efi_enter_virtual_mode() to allow the EFI initialization to refer
     to ACPI.

   - A change related to code duplication reduction in the cpufreq core
     inadvertently caused cpufreq intialization to fail for some CPUs
     handled by intel_pstate by adding checks that may fail for that
     driver, but aren't even necessary when it is used.  The issue is
     addressed by preventing those checks from run in the configurations
     in which they aren't needed.

   - If the Hardware Reduced ACPI flag is set in the ACPI tables, system
     suspend, hibernation and ACPI power off will only work when special
     sleep control and sleep status registeres are provided (their
     addresses in the ACPI tables are not zero).  If those registers are
     not available, the features in question have no chances to work, so
     they shouldn't even be regarded as supported.  That helps with
     power off in particular, because alternative power off methods may
     be used then and they may actually work"

For systems with multiple servers and routed fabric, all
northbridges get assigned to the first server. Fix this by also
using the node reported from the PCI bus. For single-fabric
systems, the northbriges are on PCI bus 0 by definition, which
are on NUMA node 0 by definition, so this is invarient on most
systems.

  Anyways:

   1) vmxnet3's netpoll doesn't perform the equivalent of an ISR, which
      is the correct implementation, like it should.  Instead it does
      something like a NAPI poll operation.  This leads to crashes.

      From Neil Horman and Arnd Bergmann.

   2) Segmentation of SKBs requires proper socket orphaning of the
      fragments, otherwise we might access stale state released by the
      release callbacks.

      This is a 5 patch fix, but the initial patches are giving
      variables and such significantly clearer names such that the
      actual fix itself at the end looks trivial.

      From Michael S.  Tsirkin.

   3) TCP control block release can deadlock if invoked from a timer on
      an already "owned" socket.  Fix from Eric Dumazet.

   4) In the bridge multicast code, we must validate that the
      destination address of general queries is the link local all-nodes
      multicast address.  From Linus Lüssing.

   5) The x86 BPF JIT support for negative offsets puts the parameter
      for the helper function call in the wrong register.  Fix from
      Alexei Starovoitov.

   6) The descriptor type used for RTL_GIGA_MAC_VER_17 chips in the
      r8169 driver is incorrect.  Fix from Hayes Wang.

   7) The xen-netback driver tests skb_shinfo(skb)->gso_type bits to see
      if a packet is a GSO frame, but that's not the correct test.  It
      should use skb_is_gso(skb) instead.  Fix from Wei Liu.

   8) Negative msg->msg_namelen values should generate an error, from
      Matthew Leach.

   9) at86rf230 can deadlock because it takes the same lock from it's
      ISR and it's hard_start_xmit method, without disabling interrupts
      in the latter.  Fix from Alexander Aring.

  10) The FEC driver's restart doesn't perform operations in the correct
      order, so promiscuous settings can get lost.  Fix from Stefan
      Wahren.

  11) Fix SKB leak in SCTP cookie handling, from Daniel Borkmann.

  12) Reference count and memory leak fixes in TIPC from Ying Xue and
      Erik Hugne.

  13) Forced eviction in inet_frag_evictor() must strictly make sure all
      frags are deleted, otherwise module unload (f.e.  6lowpan) can
      crash.  Fix from Florian Westphal.

  14) Remove assumptions in AF_UNIX's use of csum_partial() (which it
      uses as a hash function), which breaks on PowerPC.  From Anton
      Blanchard.

      The main gist of the issue is that csum_partial() is defined only
      as a value that, once folded (f.e.  via csum_fold()) produces a
      correct 16-bit checksum.  It is legitimate, therefore, for
      csum_partial() to produce two different 32-bit values over the
      same data if their respective alignments are different.

  15) Fix endiannes bug in MAC address handling of ibmveth driver, also
      from Anton Blanchard.

  16) Error checks for ipv6 exthdrs offload registration are reversed,
      from Anton Nayshtut.

  17) Externally triggered ipv6 addrconf routes should count against the
      garbage collection threshold.  Fix from Sabrina Dubroca.

  18) The PCI shutdown handler added to the bnx2 driver can wedge the
      chip if it was not brought up earlier already, which in particular
      causes the firmware to shut down the PHY.  Fix from Michael Chan.

  19) Adjust the sanity WARN_ON_ONCE() in qdisc_list_add() because as
      currently coded it can and does trigger in legitimate situations.
      From Eric Dumazet.

  20) BNA driver fails to build on ARM because of a too large udelay()
      call, fix from Ben Hutchings.

  21) Fair-Queue qdisc holds locks during GFP_KERNEL allocations, fix
      from Eric Dumazet.

If the HW Reduced ACPI mode bit is set in the FADT, ACPICA uses
the optional sleep control and sleep status registers for making
the system enter sleep states (including S5), so it is not possible
to use system sleep states or power it off using ACPI if the HW
Reduced ACPI mode bit is set and those registers are not available.

For this reason, add a new function, acpi_sleep_state_supported(),
checking if the HW Reduced ACPI mode bit is set and whether or not
system sleep states are usable in that case in addition to checking
the return value of acpi_get_sleep_type_data() and make the ACPI
sleep setup routines use that function to check the availability of
system sleep states.

Among other things, this prevents the kernel from attempting to
use ACPI for powering off HW Reduced ACPI systems without the sleep
control and sleep status registers, because ACPI power off doesn't
have a chance to work on them.  That allows alternative power off
mechanisms that may actually work to be used on those systems.  The
affected machines include Dell Venue 8 Pro, Asus T100TA, Haswell
Desktop SDP and Ivy Bridge EP Demo depot.

Age calculation in ipv6_create_tempaddr is different from the one
in addrconf_verify and doesn't consider ADDRCONF_TIMER_FUZZ_MINUS.
This can cause age in ipv6_create_tempaddr to be less than the one

The commit d3ab3ffd
(bonding: use rlb_client_info->vlan_id instead of ->tag)
remove the rlb_client_info->tag, but occur some issues,
The vlan_get_tag() will return 0 for success and -EINVAL for
error, so the client_info->vlan_id always be set to 0 if the
vlan_get_tag return 0 for success, so the client_info would
never get a correct vlan id.

We should only set the vlan id to 0 when the vlan_get_tag return error.

Fixes: d3ab3ffd (bonding: use rlb_client_info->vlan_id instead of ->tag)

We use the lp->lock inside the isr of at86rf230, that's why we need the
irqsave spinlock calls.
