tdx_mig_setup is assigned to the cgs migration framework's
savevm_state_setup API (invoked on the source side) and loadvm_state_setup
API (invoked on the destination side). The setup work includes:
- create a kvm_device from the tdx-mig driver in KVM. The device fd is
returned for later communication with the device.
- negotiate with the driver for the size if the memory to map, this
includes:
-- KVM_SET_DEVICE_ATTR: sets the configurable attr (only the migration
buffer size currently) of the device to KVM. The migration flow
currently finds and send dirty pages one by one, so the migration
buffer size set to the driver is 4KB (TAGET_PAGE_SIZE);
-- KVM_GET_DEVICE_ATTR: gets the negotiated kvm_device's attr. This
obtains from KVM the sizes of the 4 parts (i.e. mbmd buffer size,
migration buffer size, mac list buffer size, and gpa list buffer
size) of shared memory.
- map the 4 parts of shared memory.

Pull in recent TDX updates, which are not backwards compatible.
It's just to make this series runnable. It will be updated by script
scripts/update-linux-headers.sh
once TDX support is upstreamed in linux kernel

The next version of Linux will introduce boolean statistics, which
can only have 0 or 1 values. Convert them to the new QAPI fields

Update to c5eb0a61238d ("Linux 5.18-rc6"). Mechanical search and
replace of vfio defines with white space massaging.

The SEV FW >= 0.23 added a new command that can be used to query the
attestation report containing the SHA-256 digest of the guest memory
and VMSA encrypted with the LAUNCH_UPDATE and sign it with the PEK.
Note, we already have a command (LAUNCH_MEASURE) that can be used to
query the SHA-256 digest of the guest memory encrypted through the
LAUNCH_UPDATE. The main difference between previous and this command
is that the report is signed with the PEK and unlike the LAUNCH_MEASURE
command the ATTESATION_REPORT command can be called while the guest
is running.
Add a QMP interface "query-sev-attestation-report" that can be used
to get the report encoded in base64.
