First of all, thanks for splitting the patch - it is much easier to
review this way.

Then, this patch should be 12.1, i.e., the first of the split because otherwise
the previous one - which should be the next - fails building due to

drivers/crypto/ccp/psp-dev.c:26:32: fatal error: uapi/linux/psp-sev.h: No such file or directory
 #include <uapi/linux/psp-sev.h>
                                ^
Just swap them in their order.

Also, those SEV commands should be __packed, see below.

With that addressed:
