[PATCH v2 0/8] powerpc/watchpoint: Enable 2nd DAWR on baremetal and powervm

From: Ravi Bangoria
Date: Wed Jun 03 2020 - 23:35:36 EST


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@xxxxxxxxxxxxx

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.
