When we enable storage keys for a guest lazily, we reset the ACC and F values. That is correct assuming that these are 0 on a clear reset and the guest obviously has not used any key setting instruction. We also zero out the change and reference bit. This is not correct as the architecture prefers over-indication instead of under-indication for the keyless->keyed transition. This patch fixes the behaviour and always sets guest change and guest reference for all guest storage keys on the keyless -> keyed switch.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
