POWER9 with the DAWR disabled causes problems for partition migration. Either we have to fail the migration (since we lose the DAWR) or we silently drop the DAWR and allow the migration to pass. This patch does the latter and allows the migration to pass (at the cost of silently losing the DAWR). This is not ideal but hopefully the best overall solution. This approach has been acked by Paulus. With this patch kvmppc_set_one_reg() will store the DAWR in the vcpu but won't actually set it on POWER9 hardware.

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.
