Hi,
here's v2 with some of Shuah's comments integrated.
If no one has anything against it, I'll route them all through tip.
Thx.
--- Changelog:
v0: --
here's something from my todo list: remove all in-kernel tools use of that MSR and lastly drop it from the allowed-MSRs-list in the filtering.
Out-of-tree tools should do a similar, trivial conversion.
Constructive comments are, as always, appreciated.
