CVS commit: src/sys/arch/powerpc/ibm4xx

Module Name:    src
Committed By:   rin
Date:           Fri Feb 21 13:16:16 UTC 2020

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.
