In arch/alpha/include/asm/thread_info.h, THREAD_SIZE is defined as
(2*PAGE_SIZE). I tried editing arch/alpha/kernel/vmlinux.lds.S and making
that substitution manually, and the build succeeds. "thread_info.h" is
being included, so I have no idea why the build is breaking. gcc
version is 4.3.4 (Debian 4.3.4-5), and binutils version is
2.19.91.20091006.
