Linux-2.6.12-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! 2005-04-16 18:20:36 -04:00			`# List of files in the vdso, has to be asm only for now`

[PATCH] ppc64: add PT_NOTE section to vDSO This patch from Roland adds a PT_NOTE section to both 32 and 64 bits vDSOs to expose the kernel version to glibc, thus avoiding a uname syscall on every launch. This is equivalent to the patches Roland posted already for x86 and x86-64. Note: the 64 bits .note is actually using the 32 bits format. This is normal. The ELF spec specifies a different format for 64 bits .note, but for some reason, this was never properly implemented, the core dumps for example are all using 32 bits format .note, and binutils cannot even read a 64 bits format .note. Talking to our toolchain folks, they think we'd rather stick to 32 bits format .note everywhere and get the spec fixed some day ...
