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!

asm-generic: rename termios.h, signal.h and mman.h The existing asm-generic versions are incomplete and included by some architectures. New architectures should be able to use a generic version, so rename the existing files and change all users, which lets us add the new files.

[PATCH] IA64,sparc: local DoS with corrupted ELFs This prevents cross-region mappings on IA64 and SPARC which could lead to system crash. They were correctly trapped for normal mmap() calls, but not for the kernel internal calls generated by executable loading. This code just moves the architecture-specific cross-region checks into an arch-specific "arch_mmap_check()" macro, and defines that for the architectures that needed it (ia64, sparc and sparc64). Architectures that don't have any special requirements can just ignore the new cross-region check, since the mmap() code will just notice on its own when the macro isn't defined.
