Description of problem:

The link https://bugzilla.openanolis.cn/show_bug.cgi?id=5885 is about support
for AMD SEV guest live migration.

The migration of this solution is very slow because API communication between
x86 and PSP is time-consuming. In order to accelerate the migration speed,
we proposed ring buffer mode to handle the migration API.
