Last series[1] was to add basic infrastructure support for more than one watchpoint on Book3S powerpc. This series actually enables the 2nd DAWR for baremetal and powervm. Kvm guest is still not supported.
v1: https://lore.kernel.org/linuxppc-dev/20200602040106.127693-1-ravi.bangoria@linux.ibm.com
v1->v2: - Milton reported an issue with one patch in last series[1]. patch #1 fixes that. So patch#1 is new. - Rebased to powerpc/next which now has "Base support for POWER10"[2] series included.
