In ppc6xx_tlb_pte_check() the pp variable is used only once to pass it to a function parameter with the same name. Remove the local and inline the value. Also use named constant for the hex value to make it clearer. Signed-off-by: BALATON Zoltan <balaton@eik.bme.hu> --- target/ppc/mmu_common.c | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-)
