Linux kernel source tree
e5ed0fb010
Snapshot the state of the processor registers that govern page walk into a new field of struct kvm_mmu. This is a more natural representation than having it *mostly* in mmu_role but not exclusively; the delta right now is represented in other fields, such as root_level. The nested MMU now has only the CPU role; and in fact the new function kvm_calc_cpu_role is analogous to the previous kvm_calc_nested_mmu_role, except that it has role.base.direct equal to !CR0.PG. For a walk-only MMU, "direct" has no meaning, but we set it to !CR0.PG so that role.ext.cr0_pg can go away in a future patch. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> |

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.
