code32_start is meant for 16-bit real-mode bootloaders to inform the kernel where the 32-bit protected mode code starts. Nothing in the protected mode kernel except the EFI stub uses it. efi_main() currently returns boot_params, with code32_start set inside it to tell efi_stub_entry() where startup_32 is located. Since it was invoked by efi_stub_entry() in the first place, boot_params is already known. Return the address of startup_32 instead. This will allow a 64-bit kernel to live above 4Gb, for example, and it's cleaner as well.
