My copying of linux/init.h didn't go far enough. The definition of
__used singled out gcc minor version 3, but didn't care what the major
version was. This broke when unit-at-a-time was added and gcc started
throwing out initcalls.
This results in an early boot crash when ptrace tries to initialize a
process with an empty, uninitialized register set.
