History
Linus Torvalds c813e8c9df Filter MSR writes from user-space by default, and print a syslog entry if 
they happen outside the allowed set of MSRs, which is a single one for now,
 MSR_IA32_ENERGY_PERF_BIAS.
 
 The plan is to eventually disable MSR writes by default (they can still be
 enabled via allow_writes=on).
