Konstantin Belousov 319117fd57 IBRS support, AKA Spectre hardware mitigation.
It is coded according to the Intel document 336996-001, reading of the
patches posted on lkml, and some additional consultations with Intel.

For existing processors, you need a microcode update which adds IBRS
CPU features, and to manually enable it by setting the tunable/sysctl
hw.ibrs_disable to 0.  Current status can be checked in sysctl
hw.ibrs_active.  The mitigation might be inactive if the CPU feature
is not patched in, or if CPU reports that IBRS use is not required, by
IA32_ARCH_CAP_IBRS_ALL bit.
