Cyrix ARR problem in split MTRR code

Hi,

I noticed a problem in the split MTRR code that is special casing ARR #3 on Cyrix 6x86(MX) / MII CPUs. I wrote the code for the original (monolithic) mtrr.c, but I don't have my old Cyrix 6x86MX mainboard anymore. The problem is obvious though, one liner fix is attached. Patrick Mochel should have been more careful. :-)

Best regards,
Zoltán Böszörményi
