When attempting to remove by index a set of LMBs a lot of messages are displayed on the console, even when everything goes fine: pseries-hotplug-mem: Attempting to hot-remove LMB, drc index 8000002d Offlined Pages 4096 pseries-hotplug-mem: Memory at 2d0000000 was hot-removed The 2 messages prefixed by "pseries-hotplug-mem" are not really helpful for the end user, they should be debug outputs. In case of error, because some of the LMB's pages couldn't be offlined, the following is displayed on the console: pseries-hotplug-mem: Attempting to hot-remove LMB, drc index 8000003e pseries-hotplug-mem: Failed to hot-remove memory at 3e0000000 dlpar: Could not handle DLPAR request "memory remove index 0x8000003e" Again, the 2 messages prefixed by "pseries-hotplug-mem" are useless, and the generic DLPAR prefixed message should be enough. These 2 first changes are mainly triggered by the changes introduced in drmgr: https://groups.google.com/g/powerpc-utils-devel/c/Y6ef4NB3EzM/m/9cu5JHRxAQAJ Also, when adding a bunch of LMBs, a message is displayed in the console per LMB like these ones: pseries-hotplug-mem: Memory at 7e0000000 (drc index 8000007e) was hot-added pseries-hotplug-mem: Memory at 7f0000000 (drc index 8000007f) was hot-added pseries-hotplug-mem: Memory at 800000000 (drc index 80000080) was hot-added pseries-hotplug-mem: Memory at 810000000 (drc index 80000081) was hot-added When adding 1TB of memory and LMB size is 256MB, this leads to 4096 messages to be displayed on the console. These messages are not really helpful for the end user, so moving them to the DEBUG level.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
