Hey,

Can anyone tell me if it is destruktive or does it cause lose of 
performance if I set up
L1_CACHE_SHIFT_MAX as well as CONFIG_X86_L1_CACHE_SHIFT to the value of 10?

I've an Intel centrino processor with 1MB L1-Cache.

Thanx in advance

Axel

1 MB L1?

Isn't it L2?

This makes no sense. This define is for the cacheline size, not
the total size of the cache.
