CVS commit: src/sys/arch/powerpc/ibm4xx
Module Name: src
Committed By: rin

In ppc4xx_tlb_find_victim(), mark kernel stack page TLBF_REF instead of
TLBF_USED. This should be originally intended behavior of this code
- 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.
