In commit 77b533411595 ("KVM: s390: VSIE: sort out virtual/physical
address in pin_guest_page"), only pin_scb() has been updated. This
means that in unpin_scb() a virtual address was still used directly as
physical address without conversion. The resulting physical address is
obviously wrong and most of the time also invalid.
Since commit d0ef8d9fbebe ("KVM: s390: Use kvm_release_page_dirty() to
unpin "struct page" memory"), unpin_guest_page() will directly use
kvm_release_page_dirty(), instead of kvm_release_pfn_dirty(), which has
since been removed.
One of the checks that were performed by kvm_release_pfn_dirty() was to
verify whether the page was valid at all, and silently return
successfully without doing anything if the page was invalid.
When kvm_release_pfn_dirty() was still used, the invalid page was thus
silently ignored. Now the check is gone and the result is an Oops.
This also means that when running with a V!=R kernel, the page was not
released, causing a leak.
The solution is simply to add the missing virt_to_phys().
Fixes: 77b533411595 ("KVM: s390: VSIE: sort out virtual/physical address in pin_guest_page")

Bananapi R4 Board contains a MT6682A pmic which is compatible to rt5190a.
Add its node to the i2 controller.
The BananaPi R4 board has a MediaTek MT6682A PMIC, a rebrand of the
Richtek RT5190A chip, connected to the I2C0 bus.
Add the relevant node and, while at it, also configure the regulators
from this PMIC that are used on this board.
Only Buck2/Buck3 voltage can be controlled by software.
BUCK4 input is 5V from BUCK1 output, and the resistor (mapped to RP30/RP31
on BPI-R4) configures BUCK4 output to 1.8V.
LDO input is 3.3V from 3.3VD, and the resistor (mapped to RP38/RP40 on
BPI-R4) configures LDO output to 1.8V.

Commit
09d35045cd0f ("x86/sev: Avoid WARN()s and panic()s in early boot code")
replaced a panic() that could potentially hit before the kernel is even
mapped with a deadloop, to ensure that execution does not proceed when the
condition in question hits.
As Tom suggests, it is better to terminate and return to the hypervisor
in this case, using a newly invented failure code to describe the
failure condition.

At present, the SEV guest driver exclusively handles SNP guest messaging. All
routines for sending guest messages are embedded within it.
To support Secure TSC, SEV-SNP guests must communicate with the AMD Security
Processor during early boot. However, these guest messaging functions are not
accessible during early boot since they are currently part of the guest
driver.
Hence, relocate the core SNP guest messaging functions to SEV common code and
provide an API for sending SNP guest messages.
No functional change, but just an export symbol added for
snp_send_guest_request() and dropped the export symbol on
snp_issue_guest_request() and made it static.

Currently, the sev-guest driver is the only user of SNP guest messaging. All
routines for initializing SNP guest messaging are implemented within the
sev-guest driver and are not available during early boot.
In preparation for adding Secure TSC guest support, carve out APIs to allocate
and initialize the guest messaging descriptor context and make it part of
coco/sev/core.c. As there is no user of sev_guest_platform_data anymore,
remove the structure.

The sysfs core now allows instances of 'struct bin_attribute' to be
moved into read-only memory. Make use of that to protect them against
accidental or malicious modifications.
