vgic_poke_irq() checks that the attr argument passed to the vgic device
ioctl is sane. Make this check tighter by moving it to after the last
attr update.

kvm_set_gsi_routing_irqchip_check
kvm_set_gsi_routing_irqchip_check(expect_failure=true) is used to check
the error code returned by the kernel when trying to setup an invalid
gsi routing table. The ioctl fails if "pin >= KVM_IRQCHIP_NUM_PINS", so
kvm_set_gsi_routing_irqchip_check() should test the error only when
"intid >= KVM_IRQCHIP_NUM_PINS+32". The issue is that the test check is
"intid >= KVM_IRQCHIP_NUM_PINS", so for a case like "intid =
KVM_IRQCHIP_NUM_PINS" the test wrongly assumes that the kernel will
return an error. Fix this by using the right check.

The guest in vgic_irq gets its arguments in a struct. This struct used
to fit nicely in a single register so vcpu_args_set() was able to pass
it by value by setting x0 with it. Unfortunately, this args struct grew
after some commits and some guest args became random (specically
kvm_supports_irqfd).
Fix this by passing the guest args as a pointer (after allocating some
guest memory for it).

For ARM64, if no vgic is setup before the dirty log perf test, the
userspace irqchip would be used, which would affect the dirty log perf
test result.

KVM now correctly handles the OS Lock for its guests. When set, KVM
blocks all debug exceptions originating from the guest. Add test cases
to the debug-exceptions test to assert that software breakpoint,
hardware breakpoint, watchpoint, and single-step exceptions are in fact
blocked.

The stages synchronize guest and host execution.
This helps the reader and constraits the execution of the test -- if the
observed staging differs from the expected the test fails.

In order to achieve good test coverage we need to be able to invoke the
MEM_OP ioctl with all possible parametrizations.
However, for a given test, we want to be concise and not specify a long
list of default values for parameters not relevant for the test, so the
readers attention is not needlessly diverted.
Add a macro that enables this and convert the existing test to use it.
The macro emulates named arguments and hides some of the ioctl's
redundancy, e.g. sets the key flag if an access key is specified.

Split success case/copy test from error test, making them independent.
This means they do not share state and are easier to understand.
Also, new test can be added in the same manner without affecting the old
ones. In order to make that simpler, introduce functionality for the
setup of commonly used variables.

Add a selftest that enables populating a VM with the maximum amount of
guest memory allowed by the underlying architecture. Abuse KVM's
memslots by mapping a single host memory region into multiple memslots so
that the selftest doesn't require a system with terabytes of RAM.
Default to 512gb of guest memory, which isn't all that interesting, but
should work on all MMUs and doesn't take an exorbitant amount of memory
or time. E.g. testing with ~64tb of guest memory takes the better part
of an hour, and requires 200gb of memory for KVM's page tables when using
4kb pages.
To inflicit maximum abuse on KVM' MMU, default to 4kb pages (or whatever
the not-hugepage size is) in the backing store (memfd). Use memfd for
the host backing store to ensure that hugepages are guaranteed when
requested, and to give the user explicit control of the size of hugepage
being tested.
By default, spin up as many vCPUs as there are available to the selftest,
and distribute the work of dirtying each 4kb chunk of memory across all
vCPUs. Dirtying guest memory forces KVM to populate its page tables, and
also forces KVM to write back accessed/dirty information to struct page
when the guest memory is freed.
On x86, perform two passes with a MMU context reset between each pass to
coerce KVM into dropping all references to the MMU root, e.g. to emulate
a vCPU dropping the last reference. Perform both passes and all
rendezvous on all architectures in the hope that arm64 and s390x can gain
similar shenanigans in the future.
Measure and report the duration of each operation, which is helpful not
only to verify the test is working as intended, but also to easily
evaluate the performance differences different page sizes.
Provide command line options to limit the amount of guest memory, set the
size of each slot (i.e. of the host memory region), set the number of
vCPUs, and to enable usage of hugepages.

Extract the code for allocating guest memory via memfd out of
vm_userspace_mem_region_add() and into a new helper, kvm_memfd_alloc().
A future selftest to populate a guest with the maximum amount of guest
memory will abuse KVM's memslots to alias guest memory regions to a
single memfd-backed host region, i.e. needs to back a guest with memfd
memory without a 1:1 association between a memslot and a memfd instance.

The main thing that the selftest verifies is that KVM copies x2APIC's
ICR[63:32] to/from ICR2 when userspace accesses the vAPIC page via
KVM_{G,S}ET_LAPIC. KVM previously split x2APIC ICR to ICR+ICR2 at the
time of write (from the guest), and so KVM must preserve that behavior
for backwards compatibility between different versions of KVM.
It will also test other invariants, e.g. that KVM clears the BUSY
flag on ICR writes, that the reserved bits in ICR2 are dropped on writes
from the guest, etc...

Commit 2c212e1baedc ("KVM: s390: Return error on SIDA memop on normal
guest") fixed the behavior of the SIDA memops for normal guests. It
would be nice to have a way to test whether the current kernel has
the fix applied or not. Thus add a check to the KVM selftests for
these two memops.

For SEV-ES VMs with mirrors to be intra-host migrated they need to be
able to migrate with the mirror. This is due to that fact that all VMSAs
need to be added into the VM with LAUNCH_UPDATE_VMSA before
lAUNCH_FINISH. Allowing migration with mirrors allows users of SEV-ES to
keep the mirror VMs VMSAs during migration.
Adds a list of mirror VMs for the original VM iterate through during its
migration. During the iteration the owner pointers can be updated from
the source to the destination. This fixes the ASID leaking issue which
caused the blocking of migration of VMs with mirrors.

Introduce a new test for Hyper-V nSVM extensions (Hyper-V on KVM) and add
a test for enlightened MSR-Bitmap feature:
- Intercept access to MSR_FS_BASE in L1 and check that this works
with enlightened MSR-Bitmap disabled.
- Enabled enlightened MSR-Bitmap and check that the intercept still works
as expected.
- Intercept access to MSR_GS_BASE but don't clear the corresponding bit
from clean fields mask, KVM is supposed to skip updating MSR-Bitmap02 and
thus the consequent access to the MSR from L2 will not get intercepted.
- Finally, clear the corresponding bit from clean fields mask and check
that access to MSR_GS_BASE is now intercepted.
The test works with the assumption, that access to MSR_FS_BASE/MSR_GS_BASE
is not intercepted for L1. If this ever becomes not true the test will
fail as nested_svm_exit_handled_msr() always checks L1's MSR-Bitmap for
L2 irrespective of clean fields. The behavior is correct as enlightened
MSR-Bitmap feature is just an optimization, KVM is not obliged to ignore
updates when the corresponding bit in clean fields stays clear.

Introduce a test for enlightened MSR-Bitmap feature (Hyper-V on KVM):
- Intercept access to MSR_FS_BASE in L1 and check that this works
with enlightened MSR-Bitmap disabled.
- Enabled enlightened MSR-Bitmap and check that the intercept still works
as expected.
- Intercept access to MSR_GS_BASE but don't clear the corresponding bit
from 'hv_clean_fields', KVM is supposed to skip updating MSR-Bitmap02 and
thus the consequent access to the MSR from L2 will not get intercepted.
- Finally, clear the corresponding bit from 'hv_clean_fields' and check
that access to MSR_GS_BASE is now intercepted.
The test works with the assumption, that access to MSR_FS_BASE/MSR_GS_BASE
is not intercepted for L1. If this ever becomes not true the test will
fail as nested_vmx_exit_handled_msr() always checks L1's MSR-Bitmap for
L2 irrespective of 'hv_clean_fields'. The behavior is correct as
enlightened MSR-Bitmap feature is just an optimization, KVM is not obliged
to ignore updates when the corresponding bit in 'hv_clean_fields' stays
clear.

Instead of just resetting 'hv_clean_fields' to 0 on every enlightened
vmresume, do the expected cleaning of the corresponding bit on enlightened
vmwrite. Avoid direct access to 'current_evmcs' from evmcs_test to support
the change.

Pull asm-generic updates from Arnd Bergmann:
"There are three sets of updates for 5.18 in the asm-generic tree:
- The set_fs()/get_fs() infrastructure gets removed for good.
This was already gone from all major architectures, but now we can
finally remove it everywhere, which loses some particularly tricky
and error-prone code. There is a small merge conflict against a
parisc cleanup, the solution is to use their new version.
- The nds32 architecture ends its tenure in the Linux kernel.
The hardware is still used and the code is in reasonable shape, but
the mainline port is not actively maintained any more, as all
remaining users are thought to run vendor kernels that would never
be updated to a future release.
- A series from Masahiro Yamada cleans up some of the uapi header
files to pass the compile-time checks"

The nds32 architecture, also known as AndeStar V3, is a custom 32-bit
RISC target designed by Andes Technologies. Support was added to the
kernel in 2016 as the replacement RISC-V based V5 processors were
already announced, and maintained by (current or former) Andes
employees.
As explained by Alan Kao, new customers are now all using RISC-V,
and all known nds32 users are already on longterm stable kernels
provided by Andes, with no development work going into mainline
support any more.
While the port is still in a reasonably good shape, it only gets
worse over time without active maintainers, so it seems best
to remove it before it becomes unusable. As always, if it turns
out that there are mainline users after all, and they volunteer
to maintain the port in the future, the removal can be reverted.

Add some coverage of event generation to mixer-test. Rather than doing a
separate set of writes designed to trigger events we add a step to the
existing write_and_verify() which checks to see if the value we read back
from non-volatile controls matches the value before writing and that an
event is or isn't generated as appropriate. The "tests" for events then
simply check that no spurious or missing events were detected. This avoids
needing further logic to generate appropriate values for each control type
and maximises coverage.
When checking for events we use a timeout of 0. This relies on the kernel
generating any event prior to returning to userspace when setting a control.
That is currently the case and it is difficult to see it changing, if it
does the test will need to be updated. Using a delay of 0 means that we
don't slow things down unduly when checking for no event or when events

We don't check behaviour for volatile controls since we can't tell what
the behaviour is supposed to be for any given control.

Attempt to write various invalid values for control types we know about and
check that something sensible happens. The ABI isn't quite as clearly
defined as one might like, rather than generating an error when an invalid
value is written many devices will silently rewrite the value into one that
is valid for the control. The exact value chosen is not predictable so in
the case the write succeeds we just check that the value we read back is
one that is valid for the control.

This field is only used to pass along the parsed Test object from
parse_tests().
Everywhere else the `result` field is ignored.
Instead make parse_tests() explicitly return a KunitResult and Test so
we can retire the `result` field.

Build of bpf and tc-testing selftests fails when the relative path of
the build directory is specified.
make -C tools/testing/selftests O=build0
make[1]: Entering directory '/linux_mainline/tools/testing/selftests/bpf'
../../../scripts/Makefile.include:4: *** O=build0 does not exist. Stop.
make[1]: Entering directory '/linux_mainline/tools/testing/selftests/tc-testing'
../../../scripts/Makefile.include:4: *** O=build0 does not exist. Stop.
Makefiles of bpf and tc-testing include scripts/Makefile.include file.
This file has sanity checking inside it which checks the output path.
The output path is not relative to the bpf or tc-testing. The sanity
check fails. Expand the output path to get rid of this error. The fix is
the same as mentioned in commit 150a27328b68 ("bpf, preload: Fix build
when $(O) points to a relative path").

It is because libmnl.h is put in the directory of
