Ummm... Looking at arch/x86/boot/compressed/head_64.S, make_boot_params() is
only called if the stub is entered through efi_pe_entry, not if entered
through efi64_stub_entry, whereas efi_main() is called in both cases. I think
entry through efi32_stub_entry may also skip make_boot_params().

The comment on make_boot_params() suggests that this function is only used if
whoever booted the kernel didn't supply it.
