SubjectRE: [RFC][PATCH v3 2/3] Skip spin_locks in panic case and add WARN_ON()

>But this seems pretty clear that we don't need to self-NMI.

Thank you for your explanation.
Now I understand that we don't need self-NMI and efi_pstore can blindly continue in panic path
because setvariable() will succeed even if the previous call that took the exception didn't succeed.

I will submit an updated patch by removing spin_lock of efi_pstore_write() in panic path.
