KVM VMX changes for 6.15 - Fix a bug where KVM unnecessarily reads XFD_ERR from hardware and thus modifies the vCPU's XFD_ERR on a #NM due to CR0.TS=1. - Pass XFD_ERR as a psueo-payload when injecting #NM as a preparatory step for upcoming FRED virtualization support. - Decouple the EPT entry RWX protection bit macros from the EPT Violation bits as a general cleanup, and in anticipation of adding support for emulating Mode-Based Execution (MBEC). - Reject KVM_RUN if userspace manages to gain control and stuff invalid guest state while KVM is in the middle of emulating nested VM-Enter. - Add a macro to handle KVM's sanity checks on entry/exit VMCS control pairs in anticipation of adding sanity checks for secondary exit controls (the primary field is out of bits).
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.
