Convert all top-level nested VM-Enter consistency check functions to return 0/-EINVAL instead of failure codes, since now they can only ever return one failure code. This also does not give the false impression that failure information is always consumed and/or relevant, e.g. vmx_set_nested_state() only cares whether or not the checks were successful. nested_check_host_control_regs() can also now be inlined into its caller, nested_vmx_check_host_state, since the two have effectively become the same function. Based on a patch by Sean Christopherson. 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.
