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.

The rationale behind the current calculation is somewhat obscure [1]
and can yield slightly wrong dividers in certain cases, which the

suit this calculation.

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.

This has apparently never worked and could wait for v5.1. However it

-rc4. The other fixups target the new, for v5.0, nvdimm security

potential userspace lockup due to missed notifications.

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.

kvm-unit-tests' eventinj "NMI failing on IDT" test results in NMI being

be: svm_complete_interrupts() raises 'nmi_injected' flag but later we

injection upon entry so it got delivered to L1 instead of L2.

net/mlx4_core: Fix error handling when initializing CQ bufs in the driver
Procedure mlx4_init_user_cqes() handles returns by copy_to_user
incorrectly. copy_to_user() returns the number of bytes not copied.
Thus, a non-zero return should be treated as a -EFAULT error
(as is done elsewhere in the kernel). However, mlx4_init_user_cqes()
error handling simply returns the number of bytes not copied
(instead of -EFAULT).
Note, though, that this is a harmless bug: procedure mlx4_alloc_cq()
(which is the only caller of mlx4_init_user_cqes()) treats any
non-zero return as an error, but that returned error value is processed
internally, and not passed further up the call stack.

sctp: set flow sport from saddr only when it's 0
Now sctp_transport_pmtu() passes transport->saddr into .get_dst() to set
flow sport from 'saddr'. However, transport->saddr is set only when
transport->dst exists in sctp_transport_route().
If sctp_transport_pmtu() is called without transport->saddr set, like
when transport->dst doesn't exists, the flow sport will be set to 0
from transport->saddr, which will cause a wrong route to be got.
Commit
6e91b578bf3f ("sctp: re-use sctp_transport_pmtu in
sctp_transport_route") made the issue be triggered more easily
since sctp_transport_pmtu() would be called in sctp_transport_route()
after that.
In gerneral, fl4->fl4_sport should always be set to
htons(asoc->base.bind_addr.port), unless transport->asoc doesn't exist
in sctp_v4/6_get_dst(), which is the case:
sctp_ootb_pkt_new() ->
sctp_transport_route()
For that, we can simply handle it by setting flow sport from saddr only
when it's 0 in sctp_v4/6_get_dst().
