d9984bb3a1 Eliminate BxResolve call from the heart of cpu loop and move into instructions that really require this calculation. Yes, it blows the code of EVERY CPU method but it has >15% speedup ! 2008-01-10 19:37:56 +00:00

3ab94305a0 1. Fixed bug report
[ bochs-Bugs-1562172 ] TLB_init() fails to initialize priv_check array if USE_TLB 0
2. Paging is always exists for i386+
   To disable paging it is better to use normal model without special code, only by setting cr0.pg=0
