powerpc/drcinfo: Fix bugs 'ibm,drc-info' property | expand

Message

Michael Bringmann May 22, 2018, 4:36 p.m. UTC

This patch set corrects some errors and omissions in the previous
set of patches adding support for the "ibm,drc-info" property to
powerpc systems.

Unfortunately, some errors in the previous patch set break things
in some of the DLPAR operations.  In particular when attempting to
hot-add a new CPU or set of CPUs, the original patch failed to
properly calculate the available resources, and aborted the operation.
In addition, the original set missed several opportunities to compress
and reuse common code, especially, in the area of device processing.

---
Changes in V4:
  -- Update code for latest kernel checkins.
  -- Fix bug with virtual devices.
  -- Rebase on top of 4.17-rc5 kernel
  -- Simplify parser code for "ibm,drc-info" property
