Second patch tries to unmap "mapping" which is not declared. I'm on
top of jjs/master and your TPM_MEMREMAP patches are already there, so
the first patch applied cleanly. Using it, kernel still panicked on
boot:
EFI stub: Booting Linux Kernel...
EFI stub: EFI_RNG_PROTOCOL unavailable, no randomness supplied
EFI stub: Using DTB from configuration table
EFI stub: Exiting boot services and installing virtual address map...
