Make get_sev_encryption_bit() follow the ordinary i386 calling
convention, and only call it if CONFIG_AMD_MEM_ENCRYPT is actually
enabled. This clarifies the calling code, and makes it more
maintainable.

Now that the startup32_check_sev_cbit() routine can execute from
anywhere and behaves like an ordinary function, it can be moved where it
belongs.

Move startup32_check_sev_cbit() into the .text section and turn it into
an ordinary function using the ordinary 32-bit calling convention,
instead of saving/restoring the registers that are known to be live at
the only call site. This improves maintainability, and makes it possible
to move this function out of head_64.S and into a separate compilation
unit that is specific to memory encryption.
Note that this requires the call site to be moved before the mixed mode
check, as %eax will be live otherwise.

Convert startup32_load_idt() into an ordinary function and move it into
the .text section. This involves turning the rva() immediates into ones
derived from a local label, and preserving/restoring the %ebp and %ebx
as per the calling convention.
Also move the #ifdef to the only existing call site. This makes it clear
that the function call does nothing if support for memory encryption is
not compiled in.

In preparation for moving startup32_load_idt() out of head_64.S and
turning it into an ordinary function using the ordinary 32-bit calling
convention, pull the global variable reference to boot32_idt up into
startup32_load_idt() so that startup32_set_idt_entry() does not need to
discover its own runtime physical address, which will no longer be
correlated with startup_32 once this code is moved into .text.
While at it, give startup32_set_idt_entry() static linkage.

Avoid touching register %ecx in startup32_set_idt_entry(), by folding
the MOV, SHL and ORL instructions into a single ORL which no longer
requires a temp register.
This permits ECX to be used as a function argument in a subsequent
patch.

There is no need for head_32.S and head_64.S both declaring a copy of
the global 'image_offset' variable, so drop those and make the extern C
declaration the definition.
When image_offset is moved to the .c file, it needs to be placed
particularly in the .data section because it lands by default in the
.bss section which is cleared too late, in .Lrelocated, before the first
access to it and thus garbage gets read, leading to SEV guests exploding
in early boot.
This happens only when the SEV guest kernel is loaded through grub. If
supplied with qemu's -kernel command line option, that memory is always
cleared upfront by qemu and all is fine there.

Since commit 2df8220cc511 ("kbuild: build init/built-in.a just once"),
the .version file is not touched at all when KBUILD_BUILD_VERSION is
given.
If KBUILD_BUILD_VERSION is specified and the .version file is missing
(for example right after 'make mrproper'), "No such file or director"
is shown. Even if the .version exists, it is irrelevant to the version
of the current build.

make_mmu_pages_available() must be called with mmu_lock held for write.
However, if the TDP MMU is used, it will be called with mmu_lock held for
read.
This function does nothing unless shadow pages are used, so there is no
race unless nested TDP is used.
Since nested TDP uses shadow pages, old shadow pages may be zapped by this
function even when the TDP MMU is enabled.
Since shadow pages are never allocated by kvm_tdp_mmu_map(), a race
condition can be avoided by not calling make_mmu_pages_available() if the
TDP MMU is currently in use.
I encountered this when repeatedly starting and stopping nested VM.
It can be artificially caused by allocating a large number of nested TDP
SPTEs.
For example, the following BUG and general protection fault are caused in
the host kernel.

For bus-based driver, device removal is implemented as:
1 device_remove()->
2 bus->remove()->
3 driver->remove()
Driver core needs no inform from callee(bus driver) about the
result of remove callback. In that case, commit fc7a6209d571
("bus: Make remove callback return void") forces bus_type::remove
be void-returned.
Now we have the situation that both 1 & 2 of calling chain are
void-returned, so it does not make much sense for 3(driver->remove)
to return non-void to its caller.
So the basic idea behind this change is making remove() callback of
any bus-based driver to be void-returned.
This change, for itself, is for device drivers based on acpi-bus.

s390 allows to enable CONFIG_NUMA, mainly to enable a couple of system
calls which are only present if NUMA is enabled. The NUMA specific system
calls are required by a couple of applications, which wouldn't work if the
system calls wouldn't be present.
The NUMA implementation itself maps all CPUs and memory to node 0. A
special case is the generic percpu setup code, which doesn't expect an s390
like implementation and therefore emits a message/warning:
"percpu: cpu 0 has no node -1 or node-local memory".
In order to get rid of this message, and also to provide sane CPU to node
and CPU distance mappings implement a minimal setup_per_cpu_areas()
function, which is very close to the generic variant.

* Crypto
AM65/AM62:
* General purpose Timer support (system timer is still arch timer)
Fixes:
* Bunch of fixes in crypto usage and GPIO intr
* Minor schema related fixes for audio, addressing etc.
Cleanups:
* Refactor of device tree to "disable" peripherals at SoC level
for nodes that are un-usable without board level properties.
TI K3 devices have large number of peripherals of which only a
smaller subset is actually enabled on platforms. Switching
to this approach enables two benefits: lesser confusion in
creating board level devicetrees as only relevant pinned out
device nodes need enabled, as well as smaller board device
trees as most un-used peripherals don't need to explicitly
disabled.

and take advantage of it for asynchronous destroy.
When supported, the protected guest is destroyed immediately using the

If the appropriate UV feature bit is set, there is no need to perform

Until now, destroying a protected guest was an entirely synchronous
operation that could potentially take a very long time, depending on
the size of the guest, due to the time needed to clean up the address
space from protected pages.
This patch implements an asynchronous destroy mechanism, that allows a
protected guest to reboot significantly faster than previously.
This is achieved by clearing the pages of the old guest in background.
In case of reboot, the new guest will be able to run in the same
address space almost immediately.
The old protected guest is then only destroyed when all of its memory
has been destroyed or otherwise made non protected.
Two new PV commands are added for the KVM_S390_PV_COMMAND ioctl:
KVM_PV_ASYNC_CLEANUP_PREPARE: set aside the current protected VM for
later asynchronous teardown. The current KVM VM will then continue
immediately as non-protected. If a protected VM had already been
set aside for asynchronous teardown, but without starting the teardown
process, this call will fail. There can be at most one VM set aside at
any time. Once it is set aside, the protected VM only exists in the
context of the Ultravisor, it is not associated with the KVM VM
anymore. Its protected CPUs have already been destroyed, but not its
memory. This command can be issued again immediately after starting
KVM_PV_ASYNC_CLEANUP_PERFORM, without having to wait for completion.
KVM_PV_ASYNC_CLEANUP_PERFORM: tears down the protected VM previously
set aside using KVM_PV_ASYNC_CLEANUP_PREPARE. Ideally the
KVM_PV_ASYNC_CLEANUP_PERFORM PV command should be issued by userspace
from a separate thread. If a fatal signal is received (or if the
process terminates naturally), the command will terminate immediately
without completing. All protected VMs whose teardown was interrupted
will be put in the need_cleanup list. The rest of the normal KVM
teardown process will take care of properly cleaning up all remaining
protected VMs, including the ones on the need_cleanup list.

This patch adds the device tree for the "Model A" baseboard for
the SOQuartz CM4 SoM, which is not to be confused with the
Quartz64 Model A, which is the same form factor and SoC, but is
not a CM4 carrier board.
The board features a PCIe 2 x1 slot, USB 2 host ports, CSI/DSI
connectors, an eDP FFC connector, gigabit ethernet, HDMI, and a
12V DC barrel jack. Also present is a microSD card slot, 40-pin
GPIO, and a power and reset button.

This adds a device tree for the PINE64 SOQuartz blade baseboard,
a 1U rack mountable baseboard for the CM4 form factor with PoE
support designed for the SOQuartz CM4 System-on-Module.
The board takes power from either PoE or a 5V DC input, and allows
for mounting an M.2 SSD.
The board also features one USB 2.0 host port, one HDMI output,
a 3.5mm jack for UART, and the aforementioned gigabit networking
port.

This device is a clone of Odroid Go Advance, with added PWM motor, internal
gamepad connected on USB instead of just having it be on GPIO + ADC, and
missing battery shunt resistor.
Due to missing shunt resistor and lack of a workaround in rk817_charger
driver rk817_charger is not enabled in dts.
There's also an LED on GPIO 77(I *guess* PB5 on &gpio2),
that is controlled in a weird way:
- It is set to red by setting output value to 1
- Set to green by setting output value to 0
- Set to yellow by setting gpio direction to input
I have no idea how to describe that in DTS, without adding a custom
driver, for now it's just left out.
