ASoC: add helper to change platform name for all dailinks
To reuse the same machine drivers with Atom/SST, Skylake and SOF, we
need to change the default platform_name (or platforms->name in the
"modern" representation).

So far, this override was done with an automatic override, which was
broken by a set of changes for DT platforms related to deferred probe
handling.

This automatic override is actually not really needed, the machine
driver can already receive the platform name as a platform_data
parameter. This is used e.g. for HDaudio support where we have
different PCI aliases used for different platforms. We can reuse the
same mechanism and modify the machine drivers to override the dailinks
prior to registrating the card.

This will require additional work for SOF, but with this helper it'll
be just two lines of additional code per machine driver which is
reused, not the end of the world.

This helper can be simplified when all drivers have transitioned to
the "modern" representation of dailinks.

b2e9e1c881 ALSA: dice: add support for Solid State Logic Duende Classic/Mini
Duende Classic was produced by Solid State Logic in 2006, as a
first model of Duende DSP series. The following model, Duende Mini
was produced in 2008. They are designed to receive isochronous
packets for PCM frames via IEEE 1394 bus, perform signal processing by
downloaded program, then transfer isochronous packets for converted
PCM frames.

These two models includes the same embedded board, consists of several
ICs below:
 - Texus Instruments Inc, TSB41AB3 for physical layer of IEEE 1394 bus
 - WaveFront semiconductor, DICE II STD ASIC for link/protocol layer
 - Altera MAX 3000A CPLD for programs
 - Analog devices, SHARC ADSP-21363 for signal processing (4 chips)

This commit adds support for the two models to ALSA dice driver. Like
support for the other devices, packet streaming is just available.
Userspace applications should be developed if full features became
available; e.g. program uploader and parameter controller.

ASoC: pcm512x: Fix clocking calculations when not using the PLL
The rationale behind the current calculation is somewhat obscure [1]
and can yield slightly wrong dividers in certain cases, which the
machine drivers for some boards (like the HiFiBerry DAC+ Pro)
seemingly try to circumvent, by updating the rate fraction so as to
suit this calculation.

The updated calculation should correctly yield the smallest bit clock
rate that would fit the frame.

ASoC: pcm512x: Implement the set_bclk_ratio interface
Some boards, such as the HiFiBerry DAC+ Pro, use a pair of external
oscillators, to generate 44.1 or 48kHz multiples and are forced to
resort to hacks [1] in order to support 24-bit data without ending up
with fractional dividers.  This patch allows the machine driver to use
32-bit frames for 24-bit data to avoid such issues.

Although the datasheet (p. 15) seems to suggest that only a handful
of ratios are supported, it's not very explicit about it, so we allow
the full range of values supported by the underlying register in the
callback, to avoid needlessly rejecting potentially usable
configurations.

Merge tag 'libnvdimm-fixes-5.0-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm

Pull libnvdimm fixes from Dan Williams:
 "A fix for namespace label support for non-Intel NVDIMMs that implement
  the ACPI standard label method.

  This has apparently never worked and could wait for v5.1. However it
  has enough visibility with hardware vendors [1] and distro bug
  trackers [2], and low enough risk that I decided it should go in for
  -rc4. The other fixups target the new, for v5.0, nvdimm security
  functionality. The larger init path fixup closes a memory leak and a
  potential userspace lockup due to missed notifications.

    [1] https://github.com/pmem/ndctl/issues/78
    [2] https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1811785

  These have all soaked in -next for a week with no reported issues.

  Summary:

   - Fix support for NVDIMMs that implement the ACPI standard label
     methods.

   - Fix error handling for security overwrite (memory leak / userspace
     hang condition), and another one-line security cleanup"

e190161f96 ALSA: pcm: Fix tight loop of OSS capture stream
When the trigger=off is passed for a PCM OSS stream, it sets the
start_threshold of the given substream to the boundary size, so that
it won't be automatically started.  This can be problematic for a
capture stream, unfortunately, as detected by syzkaller.  The scenario
is like the following:

- In __snd_pcm_lib_xfer() that is invoked from snd_pcm_oss_read()
  loop, we have a check whether the stream was already started or the
  stream can be auto-started.
- The function at this check returns 0 with trigger=off since we
  explicitly disable the auto-start.
- The loop continues and repeats calling __snd_pcm_lib_xfer() tightly,
  which may lead to an RCU stall.

This patch fixes the bug by simply allowing the wait for non-started
stream in the case of OSS capture.  For native usages, it's supposed
to be done by the caller side (which is user-space), hence it returns
zero like before.

(In theory, __snd_pcm_lib_xfer() could wait even for the native API
 usage cases, too; but I'd like to stay in a safer side for not
 breaking the existing stuff for now.)

5cd5548ff4 KVM: x86: fix TRACE_INCLUDE_PATH and remove -I. header search paths
The header search path -I. in kernel Makefiles is very suspicious;
it allows the compiler to search for headers in the top of $(srctree),
where obviously no header file exists.

The reason of having -I. here is to make the incorrectly set
TRACE_INCLUDE_PATH working.

As the comment block in include/trace/define_trace.h says,
TRACE_INCLUDE_PATH should be a relative path to the define_trace.h

Fix the TRACE_INCLUDE_PATH, and remove the iffy include paths.

nested_get_evmcs_version() but this function checks
enlightened_vmcs_enabled flag which is not yet set so we end up returning
zero.

5ad6ece869 KVM: VMX: Move vmx_vcpu_run()'s VM-Enter asm blob to a helper function
...along with the function's STACK_FRAME_NON_STANDARD tag.  Moving the
asm blob results in a significantly smaller amount of code that is
marked with STACK_FRAME_NON_STANDARD, which makes it far less likely
that gcc will split the function and trigger a spurious objtool warning.
As a bonus, removing STACK_FRAME_NON_STANDARD from vmx_vcpu_run() allows
the bulk of code to be properly checked by objtool.

Because %rbp is not loaded via VMCS fields, vmx_vcpu_run() must manually
save/restore the host's RBP and load the guest's RBP prior to calling
vmx_vmenter().  Modifying %rbp triggers objtool's stack validation code,
and so vmx_vcpu_run() is tagged with STACK_FRAME_NON_STANDARD since it's
impossible to avoid modifying %rbp.

Unfortunately, vmx_vcpu_run() is also a gigantic function that gcc will
split into separate functions, e.g. so that pieces of the function can
be inlined.  Splitting the function means that the compiled Elf file
will contain one or more vmx_vcpu_run.part.* functions in addition to
a vmx_vcpu_run function.  Depending on where the function is split,
objtool may warn about a "call without frame pointer save/setup" in
vmx_vcpu_run.part.* since objtool's stack validation looks for exact
names when whitelisting functions tagged with STACK_FRAME_NON_STANDARD.

Up until recently, the undesirable function splitting was effectively
blocked because vmx_vcpu_run() was tagged with __noclone.  At the time,
__noclone had an unintended side effect that put vmx_vcpu_run() into a
separate optimization unit, which in turn prevented gcc from inlining
the function (or any of its own function calls) and thus eliminated gcc's
motivation to split the function.  Removing the __noclone attribute
allowed gcc to optimize vmx_vcpu_run(), exposing the objtool warning.

Kudos to Qian Cai for root causing that the fnsplit optimization is what
caused objtool to complain.

619ad846fc KVM: nSVM: clear events pending from svm_complete_interrupts() when exiting to L1
kvm-unit-tests' eventinj "NMI failing on IDT" test results in NMI being
delivered to the host (L1) when it's running nested. The problem seems to
be: svm_complete_interrupts() raises 'nmi_injected' flag but later we
decide to reflect EXIT_NPF to L1. The flag remains pending and we do NMI
injection upon entry so it got delivered to L1 instead of L2.

It seems that VMX code solves the same issue in prepare_vmcs12(), this was
introduced with code refactoring in commit 5f3d579997 ("KVM: nVMX: Rework
