[ Please CC me I am not subscribed to this ML ] [1] says: " This option is only required for vmlinux on 64-bit, to enforce 2MiB alignment, so set it in LDFLAGS_vmlinux instead of KBUILD_LDFLAGS. Also drop the ld-option check: this option was added in binutils-2.18 and all the other places that use it already don't have the check.
This reduces the size of the intermediate ELF files arch/x86/boot/setup.elf and arch/x86/realmode/rm/realmode.elf by about 2MiB each. The binary versions are unchanged. Move the LDFLAGS settings to all be together and just after CFLAGS settings are done.
