Re: [PATCH 0/4] Fixes for SEV-SNP CC blob and CPUID table handling

["Yao, Jiewen" <jiewen.yao@intel.com>]

Hi Roth
I got weird merge conflict when I try to apply the patches from email.

Would you please resubmit the patch based on latest code base?

Once I see the new version, I will try to merge them again.

Thank you
Yao, Jiewen
