This adds a few last pieces of the support for radix guests: * Implement the backends for the KVM_PPC_CONFIGURE_V3_MMU and KVM_PPC_GET_RMMU_INFO ioctls for radix guests * On POWER9, allow secondary threads to be on/off-lined while guests are running. * Set up LPCR and the partition table entry for radix guests. * Don't allocate the rmap array in the kvm_memory_slot structure on radix. * Don't try to initialize the HPT for radix guests, since they don't have an HPT. * Take out the code that prevents the HV KVM module from initializing on radix hosts. At this stage, we only support radix guests if the host is running in radix mode, and only support HPT guests if the host is running in HPT mode. Thus a guest cannot switch from one mode to the other, which enables some simplifications. Signed-off-by: Paul Mackerras <paulus@ozlabs.org> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
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.
