Texas Instruments K3 SoCs contain an RTI (Real Time Interrupt) module
which can be used as a watchdog. This IP provides a support for
windowed watchdog mode, in which the watchdog must be petted within
a certain time window. If it is petted either too soon, or too late,
a watchdog error will be triggered.

If the heartbeat module param is not specified we would get an error
message
watchdog: f1020300.watchdog: driver supplied timeout (4294967295) out of range
watchdog: f1020300.watchdog: falling back to default timeout (171)
This is because we were initialising heartbeat to -1. By removing the
initialisation (thus letting the C run time initialise it to 0) we
silence the warning message and the default timeout is still used.

Currently the watchdog core does not initialize the last_hw_keepalive
time during watchdog startup. This will cause the watchdog to be pinged
immediately if enough time has passed from the system boot-up time, and
some types of watchdogs like K3 RTI does not like this.
To avoid the issue, setup the last_hw_keepalive time during watchdog
startup.

Many watchdog drivers use watchdog_stop_on_reboot() helper in order
to stop the watchdog on system reboot. Unfortunately, this logic is
coded in driver's probe function and doesn't allows user to decide what
to do during shutdown/reboot.
On the other side, Xen and Qemu watchdog drivers (xen_wdt and i6300esb)
may be configured to either send NMI or turn off/reboot VM as
the watchdog action. As the kernel may stuck at any state, sending NMIs
can't reliably reboot the VM.
At Arista, we benefited from the following set-up: the emulated watchdogs
trigger VM reset and softdog is set to catch less severe conditions to
generate vmcore. Just before reboot watchdog's timeout is increased
to some good-enough value (3 mins). That keeps watchdog always running
and guarantees that VM doesn't stuck.
Provide new stop_on_reboot module parameter to let user control
watchdog's reboot policy.

Given that this driver probes only on DT based platforms and those DT

When an EVMCS enabled L1 guest on KVM will tries doing enlightened VMEnter
with EVMCS GPA = 0 the host crashes because the
evmcs_gpa != vmx->nested.hv_evmcs_vmptr
condition in nested_vmx_handle_enlightened_vmptrld() will evaluate to
false (as nested.hv_evmcs_vmptr is zeroed after init). The crash will
happen on vmx->nested.hv_evmcs pointer dereference.
Another problematic EVMCS ptr value is '-1' but it only causes host crash
after nested_release_evmcs() invocation. The problem is exactly the same as
with '0', we mistakenly think that the EVMCS pointer hasn't changed and
thus nested.hv_evmcs_vmptr is valid.
Resolve the issue by adding an additional !vmx->nested.hv_evmcs
check to nested_vmx_handle_enlightened_vmptrld(), this way we will
always be trying kvm_vcpu_map() when nested.hv_evmcs is NULL
and this is supposed to catch all invalid EVMCS GPAs.
Also, initialize hv_evmcs_vmptr to '0' in nested_release_evmcs()
to be consistent with initialization where we don't currently
set hv_evmcs_vmptr to '-1'.

KVM: s390: Fully do the CPU resets as intended
With 7de3f1423f ("KVM: s390: Add new reset vcpu API") we clarified
the meaning of the reset ioctl to fully reset the CPU and not only the
parts that can not be handled by userspace. Turns out that we missed
some parts.
Previously all fields of structure kvm_lapic_irq were not initialized
before it was passed to kvm_bitmap_or_dest_vcpus(). Which will cause
an issue when any of those fields are used for processing a request.
For example not initializing the msi_redir_hint field before passing
to the kvm_bitmap_or_dest_vcpus(), may lead to a misbehavior of
kvm_apic_map_get_dest_lapic(). This will specifically happen when the
kvm_lowest_prio_delivery() returns TRUE due to a non-zero garbage
value of msi_redir_hint, which should not happen as the request belongs
to APIC fixed delivery mode and we do not want to deliver the
interrupt only to the lowest priority candidate.
This patch initializes all the fields of kvm_lapic_irq based on the
values of ioapic redirect_entry object before passing it on to
kvm_bitmap_or_dest_vcpus().

Enable ENCLS-exiting (and thus set vmcs.ENCLS_EXITING_BITMAP) only if
the CPU supports SGX1. Per Intel's SDM, all ENCLS leafs #UD if SGX1
is not supported[*], i.e. intercepting ENCLS to inject a #UD is
unnecessary.
Avoiding ENCLS-exiting even when it is reported as supported by the CPU
works around a reported issue where SGX is "hard" disabled after an S3
suspend/resume cycle, i.e. CPUID.0x7.SGX=0 and the VMCS field/control
are enumerated as unsupported. While the root cause of the S3 issue is
unknown, it's definitely _not_ a KVM (or kernel) bug, i.e. this is a
workaround for what is most likely a hardware or firmware issue. As a
bonus side effect, KVM saves a VMWRITE when first preparing vmcs01 and
vmcs02.
Note, SGX must be disabled in BIOS to take advantage of this workaround
[*] The additional ENCLS CPUID check on SGX1 exists so that SGX can be
globally "soft" disabled post-reset, e.g. if #MC bits in MCi_CTL are
cleared. Soft disabled meaning disabling SGX without clearing the
primary CPUID bit (in leaf 0x7) and without poking into non-SGX
CPU paths, e.g. for the VMCS controls.

Commit b9c6ff94e4 ("iommu/amd: Re-factor guest virtual APIC
(de-)activation code") accidentally left out the ir_data pointer when
calling modity_irte_ga(), which causes the function amd_iommu_update_ga()
to return prematurely due to struct amd_ir_data.ref is NULL and
the "is_run" bit of IRTE does not get updated properly.
This results in bad I/O performance since IOMMU AVIC always generate GA Log
entry and notify IOMMU driver and KVM when it receives interrupt from the
PCI pass-through device instead of directly inject interrupt to the vCPU.
Fixes by passing ir_data when calling modify_irte_ga() as done previously.

VMD subdevices are created with a PCI domain ID of 0x10000 or
higher.
These subdevices are also handled like all other PCI devices by
dmar_pci_bus_notifier().
However, when dmar_alloc_pci_notify_info() take records of such devices,
it will truncate the domain ID to a u16 value (in info->seg).
The device at (e.g.) 10000:00:02.0 is then treated by the DMAR code as if
it is 0000:00:02.0.
In the unlucky event that a real device also exists at 0000:00:02.0 and
also has a device-specific entry in the DMAR table,
dmar_insert_dev_scope() will crash on:
BUG_ON(i >= devices_cnt);
That's basically a sanity check that only one PCI device matches a
single DMAR entry; in this case we seem to have two matching devices.
Fix this by ignoring devices that have a domain number higher than
what can be looked up in the DMAR table.
This problem was carefully diagnosed by Jian-Hong Pan.

"A few fixes that should go into this release. This contains:
- Fix for a corruption issue with the s390 dasd driver (Stefan)
- Fixup/improvement for the flush insertion change that we had in
this series (Ming)
- Fix for the partition suppor for host aware zoned devices
(Shin'ichiro)
- Fix incorrect blk-iocost comparison (Tejun)
The diffstat looks large, but that's a) mostly dasd, and b) the flush
fix from Ming adds a big comment"

afs_put_addrlist() casts kfree() to rcu_callback_t. Apart from being wrong
in theory, this might also blow up when people start enforcing function
types via compiler instrumentation, and it means the rcu_head has to be
first in struct afs_addr_list.
Use kfree_rcu() instead, it's simpler and more correct.

Lockdep reports "WARNING: lock held when returning to user space!" due to
async write holding freeze lock over the write. Apparently aio.c already
deals with this by lying to lockdep about the state of the lock.
Do the same here. No need to check for S_IFREG() here since these file ops
are regular-only.

Fix up two bugs in the coversion to xino_mode:
1. xino=off does not always end up in disabled mode
2. xino=auto on 32bit arch should end up in disabled mode
Take a proactive approach to disabling xino on 32bit kernel:
1. Disable XINO_AUTO config during build time
2. Disable xino with a warning on mount time
As a by product, xino=on on 32bit arch also ends up in disabled mode.
We never intended to enable xino on 32bit arch and this will make the
rest of the logic simpler.
