The existing X86_FEATURE_VNMI is a synthetic feature flag that exists purely to maintain /proc/cpuinfo's ABI, the "real" Intel vNMI feature flag is tracked as VMX_FEATURE_VIRTUAL_NMIS, as the feature is enumerated through VMX MSRs, not CPUID. AMD is also gaining virtual NMI support, but in true VMX vs. SVM form, enumerates support through CPUID, i.e. wants to add real feature flag for vNMI. Redefine the syntheic X86_FEATURE_VNMI to AMD's real CPUID bit to avoid having both X86_FEATURE_VNMI and e.g. X86_FEATURE_AMD_VNMI. Signed-off-by: Sean Christopherson <seanjc@google.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.
