[$] A possible end to the FSGSBASE saga
The FSGSBASE
patch series is up to its thirteenth version as of late May. It
enables some "new"
instructions for the x86 architecture, opening the way for a number of
significant performance improvements. One might think that such a patch
series would be a shoo-in, but FSGSBASE has had a troubled history;
meanwhile, the delays in getting it merged may have led to a number of
users installing root holes on their Linux systems in the hope of improving
security.
