trafgen: let the kernel check min/max transm. unit boundaries
Let AF_PACKET do this job to fail in case boundaries are too small or too large. I found it quite useful for testing the kernel. Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>

fix the situation by moving the update_fdt_memmap() call into the callback function invoked by efi_exit_boot_services() right before it calls the ExitBootServices() UEFI service (which is arguably a better place for it anyway) Note that disabling the MMU in ExitBootServices() is not compliant with the UEFI spec, and carries great risk due to the fact that switching from cached to uncached memory accesses halfway through compiler generated code (i.e., involving a stack) can never be done in a way that is architecturally safe.
