I saw some failures in the spr tests running on a power9 powernv system:

$ TESTNAME=sprs TIMEOUT=90s ACCEL= ./powerpc/run powerpc/sprs.elf -smp
1 |grep FAIL
FAIL: WORT      ( 895):    0x00000000c0deba80 <==> 0x0000000000000000

$ MIGRATION=yes TESTNAME=sprs-migration TIMEOUT=90s ACCEL=
./powerpc/run powerpc/sprs.elf -smp 1 -append '-w' | grep FAIL
FAIL: SRR0      (  26):    0xcafefacec0debabc <==> 0x0000000000402244
FAIL: SRR1      (  27):    0xc0000006409ebab6 <==> 0x8000000000001001

On a power8 powernv:
