- Fix rare crashe in the intr_lapic_tlb_bcast() handler: save and setup
%fs on i386, %gs on amd64 registers, before using them. Otherwise, it
might be invalid/garbage, eg. IPI can interrupt userspace.
- Explicitly initialize per-CPU emap generation number.
Thanks <drochner> for reporting and testing of patch.
