If you're the author, how come it's Ralf's copyright here?

Queued for 2.6.39, thanks!
But: this is a rather short cpu-feature-overrides.h file. You can shrink
the kernel significantly and get a little performance boost by further
defines in that file. In particular defining the symbols for cache and
TLB properties such as the cpu_dcache_line_size and cpu_icache_line_size
are very effective.
