stable inclusion from stable-5.10.13 commit cffcb5e0fe2c994f0aa5d01b3c16e3f8a59350aa bugzilla: 47995 -------------------------------- commit 9a78e158 upstream. VMX also uses KVM_REQ_GET_NESTED_STATE_PAGES for the Hyper-V eVMCS, which may need to be loaded outside guest mode. Therefore we cannot WARN in that case. However, that part of nested_get_vmcs12_pages is _not_ needed at vmentry time. Split it out of KVM_REQ_GET_NESTED_STATE_PAGES handling, so that both vmentry and migration (and in the latter case, independent of is_guest_mode) do the parts that are needed.
