Until now, the EFI stub was only setting the 32 bit cmd_line_ptr in
the setup_header structure, so on 64 bit platforms this could be truncated.
This patch adds setting the upper bits of the buffer address in
ext_cmd_line_ptr. This case was likely never hit, as the allocation
for this buffer is

This is a very simple test that makes system calls with TF set.
This test currently fails when running the 32-bit build on a 64-bit
kernel on an Intel CPU. This bug is fixed by a patch in -mm called
"ptrace-x86-fix-the-tif_forced_tf-logic-in-handle_signal.patch":
