Linux-2.6.12-rc2v2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

32 | The 2.4 kernel changed the kernel start address from 0x310000 | ||

37 | If you're using aboot 0.7 or later, the bootloader will examine the | ||
38 | ELF headers to determine where to transfer control. Unfortunately, | ||
39 | most older bootloaders -- APB or MILO -- hardcoded the kernel start | ||
40 | address rather than examining the ELF headers, and the result is a | ||
41 | hard lockup. | ||
