The IA64 patch adds -g to CFLAGS. All the debugging information bloats
vmlinux. For the bootable kernel, I run
strip -g vmlinux -o /boot/efi/vmlinux
You can boot from the unstripped vmlinux, the IA64 loader ignores the
debug data. But the oversized kernels are slower to load and they take
up a lot of space in /boot/efi. Don't understand your compile problem,
make -j4 modules vmlinux
works for me in native IA64 mode (not cross compiling).
