#     x86/cpufeatures: Add CPUID_LNX_5 to track recently added Linux-defined word
#     
#     Add CPUID_LNX_5 to track cpufeatures' word 21, and add the appropriate
#     compile-time assert in KVM to prevent direct lookups on the features in
#     CPUID_LNX_5.  KVM uses X86_FEATURE_* flags to manage guest CPUID, and so
#     must translate features that are scattered by Linux from the Linux-defined
#     bit to the hardware-defined bit, i.e. should never try to directly access
#     scattered features in guest CPUID.
#     
#     Opportunistically add NR_CPUID_WORDS to enum cpuid_leafs, along with a
#     compile-time assert in KVM's CPUID infrastructure to ensure that future
#     additions update cpuid_leafs along with NCAPINTS.
#     
#     No functional change intended.
#
