Raw Normal View History

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!

x86: use generic register names in struct sigcontext Switch struct sigcontext (defined in <asm/sigcontext*.h>) to using register names withut e- or r-prefixes for both 32- and 64-bit x86.
