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!!
