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!

2 | initramfs_data includes the compressed binary that is the | ||
3 | filesystem used for early user space. | ||
4 | Note: Older versions of "as" (prior to binutils 2.11.90.0.23 | ||
5 | released on 2001-07-14) dit not support .incbin. | ||
6 | If you are forced to use older binutils than that then the | ||
7 | following trick can be applied to create the resulting binary: | ||
8 | |||
9 | |||
10 | ld -m elf_i386 --format binary --oformat elf32-i386 -r \ | ||
11 | -T initramfs_data.scr initramfs_data.cpio.gz -o initramfs_data.o | ||
12 | ld -m elf_i386 -r -o built-in.o initramfs_data.o | ||
13 | |||
14 | initramfs_data.scr looks like this: | ||
15 | SECTIONS | ||
16 | { | ||
17 | .init.ramfs : { *(.data) } | ||
18 | } | ||
19 | |||
20 | The above example is for i386 - the parameters vary from architectures. | ||
21 | Eventually look up LDFLAGS_BLOB in an older version of the | ||
22 | arch/$(ARCH)/Makefile to see the flags used before .incbin was introduced. | ||
23 | |||
24 | Using .incbin has the advantage over ld that the correct flags are set | ||
25 | in the ELF header, as required by certain architectures. | ||
