Including some tuning for non selected x86 CPUs too.
when it has moderate overhead. This is intended for generic
distributions kernels.

Seriously, it doesn't parse. I can't decide if "when" in that sentence is
the wrong word, or if it snuck in uncapitalized and shouldn't be there at
all. I don't feel to "too" in the first sentence belongs, it doesn't refer
to several things.

Its okay. You want the biggest possible X86_L1_CACHE_SHIFT for
X86_GENERIC, and it is the one for MPENTIUM4 (128 bytes).
Otherwise you will degrade performance on P4 when running generic kernel.
