Extract the reserved SPTE check and print helpers in get_mmio_spte() to new helpers so that KVM can also WARN on reserved badness when making a SPTE. Tag the checking helper with __always_inline to improve the probability of the compiler generating optimal code for the checking loop, e.g. gcc appears to avoid using %rbp when the helper is tagged with a vanilla "inline". No functional change intended. Signed-off-by: Sean Christopherson <seanjc@google.com> Message-Id: <20210622175739.3610207-48-seanjc@google.com> 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.
