The best would be to:

1. rename all the feature bits which have inconsistent names in their
    #defines and in /proc/cpuinfo;
2. generate the /proc/cpuinfo table
    (arch/x86/kernel/cpu/feature_names.c) automatically from
    cpufeature.h.

2. is quite trivial, and 1. can be done largely automatically.  I will 
experiment with this.
