We have soooo many syscalls declared in .c files. We had a bug due | to this a while back. Problem is, we have no anointed header in which to | place them. include/linux/syscalls.h would suit. And unistd.h for | arch-specific syscalls. But that's not appropriate to this patch. I am working on this. Is anyone else? I have parts 2.6.1-non-arch* ready for testing, I believe, except that it will likely require more changes/additions. I have begun on 2.6.1-arch* but still have a ways to go. Caveats: I have only patched 2.6.1. I will update patches for 2.6.2-rc-current. I have only tested by building allmodconfig on P4. Have not test-booted yet.

I'd really like to see the extern go, if only to discourage that particular bit of cargo cult programming.
