Joerg Roedel bffe30dd9f x86/sev-es: Use __copy_from_user_inatomic() ... The #VC handler must run in atomic context and cannot sleep. This is a problem when it tries to fetch instruction bytes from user-space via copy_from_user(). Introduce a insn_fetch_from_user_inatomic() helper which uses __copy_from_user_inatomic() to safely copy the instruction bytes to kernel memory in the #VC handler.
