pseries supports two types of credits - Default (uses normal priority FIFO) and Qality of service (QoS uses high priority FIFO). The user decides the number of QoS credits and sets this value with HMC interface. The total credits for QoS capabilities can be changed dynamically with HMC interface which invokes drmgr to communicate to the kernel. This patch creats 'update_total_credits' entry for QoS capabilities so that drmgr command can write the new target QoS credits in sysfs. Instead of using this value, the kernel gets the new QoS capabilities from the hypervisor whenever update_total_credits is updated to make sure sync with the QoS target credits in the hypervisor.

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.
