This check is unnecessary as x86 update_cr8_intercept() which calls
this VMX/SVM specific callback already performs this check.

Intel SDM section 25.2 OTHER CAUSES OF VM EXITS specifies the following
on INIT signals: "Such exits do not modify register state or clear pending
events as they would outside of VMX operation."
When commit 4b9852f4f389 ("KVM: x86: Fix INIT signal handling in various CPU states")
was applied, I interepted above Intel SDM statement such that
INIT_SIGNAL exit don’t consume the LAPIC INIT pending event.
However, when Nadav Amit run matching kvm-unit-test on a bare-metal
machine, it turned out my interpetation was wrong. i.e. INIT_SIGNAL
exit does consume the LAPIC INIT pending event.
(See: https://www.spinics.net/lists/kvm/msg196757.html)
Therefore, fix KVM code to behave as observed on bare-metal.

Commit 4b9852f4f389 ("KVM: x86: Fix INIT signal handling in various CPU states")
fixed KVM to also latch pending LAPIC INIT event when vCPU is in VMX
operation.
However, current API of KVM_SET_MP_STATE allows userspace to put vCPU
into KVM_MP_STATE_SIPI_RECEIVED or KVM_MP_STATE_INIT_RECEIVED even when
vCPU is in VMX operation.
Fix this by introducing a util method to check if vCPU state latch INIT
signals and use it in KVM_SET_MP_STATE handler.

fixed KVM to also latch pending LAPIC INIT event when vCPU is in VMX

However, current API of KVM_SET_VCPU_EVENTS defines this field as
part of SMM state and only set pending LAPIC INIT event if vCPU is
specified to be in SMM mode (events->smi.smm is set).
Change KVM_SET_VCPU_EVENTS handler to set pending LAPIC INIT event
by latched_init field regardless of if vCPU is in SMM mode or not.

It's enough to check the exit value and issue a direct call to avoid
the retpoline for all the common vmexit reasons.
Of course CONFIG_RETPOLINE already forbids gcc to use indirect jumps
while compiling all switch() statements, however switch() would still
allow the compiler to bisect the case value. It's more efficient to
prioritize the most frequent vmexits instead.
The halt may be slow paths from the point of the guest, but not
necessarily so from the point of the host if the host runs at full CPU
capacity and no host CPU is ever left idle.

There are various of flows which require tids flushing
(disconnection, suspend, etc...).
Currently, when the driver instructs the FW to flush
he masks all the data tids(0-7).
However, the driver doesn't set the management tid (#15)
which cause the FW not to flush it.
When the FW tries to remove the mgmt queue he throws an assert
since it is not an empty queue.
instead of just set only the data tids set everything and let
the FW ignore the invalid tids.

Add platform support for the new IP found on sam9x60 SoC. For this
version, if the peripheral clk is above 100MHz, the HALFR bit must be
set. This bit is available only if the IP can generate a random number
every 168 cycles (instead of 84).

Julian Wiedmann says:
====================
s390/qeth: updates 2019-11-14
please apply the following qeth patches to net-next.
Along with the usual cleanups, this
(1) reduces collateral packet loss in the RX path when dealing with
bad packets and/or allocation errors, and
(2) simplifies how the L3 driver deals with mcast IP addresses.

Given the way how the sysfs attributes are registered / unregistered,
the show/store helpers will never be called with a NULL drvdata.
