This makes __prombss its own section, and for now store
it in .bss.
This will give us the ability later to store it elsewhere
and/or free it after boot (it's about 8KB).

"of: overlay: add missing of_node_get() in __of_attach_node_sysfs"
added a missing of_node_get() to __of_attach_node_sysfs(). This
results in a refcount imbalance for nodes attached with
dlpar_attach_node(). The calling sequence from dlpar_attach_node()
to __of_attach_node_sy

There is a matching of_node_put() in __of_detach_node_sysfs()
Remove misleading comment from function header comment for
of_detach_node().
This patch may result in memory leaks from code that directly calls

From: Frank Rowand
The refcount of a newly added overlay node decrements to one
(instead of zero) when the overlay changeset is destroyed. This
change will cause the final decrement be to zero.
After applying this patch, new validation warnings will be
reported from the devicetree unittest duri
From: Frank Rowand
Add checks:
- attempted kfree due to refcount reaching zero before overlay
is removed
- properties linked to an overlay node when the node is removed
- node refcount > one during node removal in a changeset destroy,
if the node was created by the changeset
After
From: Frank Rowand
Add checks to (1) overlay apply process and (2) memory freeing
triggered by overlay release. The checks are intended to detect
possible memory leaks and invalid overlays.
The checks revealed bugs in existing code. Fixed the bugs.
While fixing bugs, noted other issues, which
There's some antiquated debug output that's trying
to do a hand-made hexdump and turning into horrible
1-byte-per-line output these days.
Use print_hex_dump() instead

Adds a driver that implements support for enabling and accessing PAPR
SCM regions. Unfortunately due to how the PAPR interface works we can't
use the existing of_pmem driver (yet) because:
a) The guest is required to use the H_SCM_BIND_MEM h-call to add

This patch implements support for discovering storage class memory
devices at boot and for handling hotplug of new regions via RTAS
hotplug events.

Unfortunately you seem to have made a mistake. My email address is
