sure that you don't confuse that with CPU_TLB_SIZE?

CPU_TLB_SIZE will always be a 2^n value because of its definition

#define CPU_TLB_SIZE (1 << CPU_TLB_BITS)


but honestly, I don't know (that's why i asked in the first place ;-) )

can someone back up thiemo's opinion? (or can you give me a hint on where this 
constraint is necessary?)

thanks!!
