8e8678e740 KVM: s390: Add capability that forwards operation exceptions
Setting KVM_CAP_S390_USER_OPEREXEC will forward all operation
exceptions to user space. This also includes the 0x0000 instructions
managed by KVM_CAP_S390_USER_INSTR0. It's helpful if user space wants
to emulate instructions which do not (yet) have an opcode.

While we're at it refine the documentation for
KVM_CAP_S390_USER_INSTR0.

61cee97f40 KVM: selftests: Add wrappers for mmap() and munmap() to assert success
Add and use wrappers for mmap() and munmap() that assert success to reduce
a significant amount of boilerplate code, to ensure all tests assert on
failure, and to provide consistent error messages on failure.

No functional change intended.

KVM selftests changes for 6.18

 - Add #DE coverage in the fastops test (the only exception that's guest-
   triggerable in fastop-emulated instructions).

 - Fix PMU selftests errors encountered on Granite Rapids (GNR), Sierra
   Forest (SRF) and Clearwater Forest (CWF).

 - Minor cleanups and improvements

8911c7dbc6 KVM: arm64: selftests: Create a VGICv3 for 'default' VMs
Start creating a VGICv3 by default unless explicitly opted-out by the
test. While having an interrupt controller is nice, the real benefit
here is clearing a hurdle for EL2 VMs which mandate the presence of a
VGIC.

3223906677 KVM: s390: selftests: Streamline uc_skey test to issue iske after sske
In some rare situations a non default storage key is already set on the
memory used by the test. Within normal VMs the key is reset / zapped
when the memory is added to the VM. This is not the case for ucontrol
VMs. With the initial iske check removed this test case can work in all
situations. The function of the iske instruction is still validated by
the remaining code.

63e7151989 KVM: s390: selftests: fix ucontrol memory region test
With the latest patch, attempting to create a memslot from userspace
will result in an EEXIST error for UCONTROL VMs, instead of EINVAL,
since the new memslot will collide with the internal memslot. There is
no simple way to bring back the previous behaviour.

This is not a problem, but the test needs to be fixed accordingly.

LoongArch KVM changes for v6.14

1. Clear LLBCTL if secondary mmu mapping changed.
2. Add hypercall service support for usermode VMM.

This is a really small changeset, because the Chinese New Year
(Spring Festival) is coming. Happy New Year!

67730e6c53 KVM: selftests: Use canonical $(ARCH) paths for KVM selftests directories
Use the kernel's canonical $(ARCH) paths instead of the raw target triple
for KVM selftests directories.  KVM selftests are quite nearly the only
place in the entire kernel that using the target triple for directories,
tools/testing/selftests/drivers/s390x being the lone holdout.

Using the kernel's preferred nomenclature eliminates the minor, but
annoying, friction of having to translate to KVM's selftests directories,
e.g. for pattern matching, opening files, running selftests, etc.

Opportunsitically delete file comments that reference the full path of the
file, as they are obviously prone to becoming stale, and serve no known
purpose.
