The 32-bit 7300LC CPU and the 64-bit PCX-W 8500 CPU use different
diag instructions to save or restore the CPU registers to/from
the shadow registers.
Implement those per-CPU architecture diag instructions to fix those
parts of the HP ODE testcases (L2DIAG and WDIAG, section 1) which test
the shad
Split trans_diag into per-operation functions.

Don't do all the decode for diag in trans_diag; do it in
decodetree instead. Add {get,put}shadowregs for ODE tests.

This series adds ARM Nested Virtualization support in KVM mode.
This is a respin of previous contributions from Miguel [1] and Haibo [2].
This was tested with Marc's v11 [3] on Ampere HW with fedora L1 guest and
L2 guests booted without EDK2. However it does not work yet with
EDK2 but it looks unr

KVM_CAP_ARM_EL2 must be supported by the cpu to enable ARM_FEATURE_EL2.
In case the host does support NV, expose the feature.

For now let's only import the pieces needed to run NV on KVM.
Later on this will be replaced by a standard and comprehensive
linux header update using scripts/update-linux-headers.sh.
For now the changes are taken from

Up to now virt support on guest has been only supported with TCG.
Now it becomes feasible to use it with KVM acceleration.
Also check only in-kernel GICv3 is used along with KVM EL2.

Allow virt arm machine to set the interrupt ID for the KVM
GIC maintenance interrupt.
This setting must be done before the KVM_DEV_ARM_VGIC_CTRL_INIT
hence the choice to perform the setting in the GICv3 realize
instead of proceeding the same way as kvm_arm_pmu_set_irq().

Hi Maintainers, this is my first attempt trying to standardise the
grammar around migration qtests. I am not sure at multiple places on
whether a particular string is placed at the right place with the
right grammar. Please comment on the patch, if anything you feel can
be improvised in the existi
