Modified Files: src/sys/arch/powerpc/ibm4xx: pmap.c Log Message: In ppc4xx_tlb_find_victim(), mark kernel stack page TLBF_REF instead of TLBF_USED. This should be originally intended behavior of this code segment, because - TLBF_USED is already checked just before, so marking this page TLBF_USED is no-op. - TLBF_REF flag exempts that page from being flushed from TLB in next scan, when kernel stack may be still there with high probability.
