| commit 7c1fed03b9fa32d4323d5caa6a9c7dcdd7eba767 upstream |
| |
| 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. |
