Linux kernel source tree

In some cases, the handling of quirks is split between platform-specific code and generic code, or it is done entirely in generic code, but the relevant bug does not trigger on some platforms; for example, this will be the case for "ignore guest PAT". Allow unaffected vendor modules to disable handling of a quirk for all VMs via a new entry in kvm_caps. Such quirks remain available in KVM_CAP_DISABLE_QUIRKS2, because that API tells userspace that KVM *knows* that some of its past behavior was bogus or just undesirable. In other words, it's plausible for userspace to refuse to run if a quirk is not listed by KVM_CAP_DISABLE_QUIRKS2, so preserve that and make it part of the API. As an example, mark KVM_X86_QUIRK_CD_NW_CLEARED as auto-disabled on Intel systems. 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 reStructuredText 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.
