perf test: S390 does not support watchpoints in test 22
S390 does not support the perf_event_open system call for attribute type PERF_TYPE_BREAKPOINT. This results in test failure for test 22: [root@s8360046 perf]# ./perf test 22 22: Watchpoint : 22.1: Read Only Watchpoint : FAILED! 22.2: Write Only Watchpoint : FAILED! 22.3: Read / Write Watchpoint : FAILED! 22.4: Modify Watchpoint : FAILED! [root@s8360046 perf]# Add s390 support to avoid these tests being executed on s390 platform: [root@s8360046 perf]# ./perf test 22 [root@s8360046 perf]# ./perf test -v 22 22: Watchpoint : Disabled [root@s8360046 perf]# Signed-off-by: Thomas Richter <tmricht@linux.ibm.com> Reviewed-by: Ravi Bangoria <ravi.bangoria@linux.ibm.com> Cc: Heiko Carstens <heiko.carstens@de.ibm.com> Cc: Hendrik Brueckner <brueckner@linux.vnet.ibm.com> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Link: http://lkml.kernel.org/r/20180928105335.67179-1-tmricht@linux.ibm.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
