As I have yet to understand the inner workings of emap, I'd like to know
if it is possible to wrap i386_cpu_switch_pmap() around uvm_emap
functions, like this:

u_int gen = uvm_emap_gen_return();

Sure.  Both calls just get/update the generation numbers (see uvm_emap.c).

However, there are some thoughts to revisit current UVM emap, so I would
suggest you to not spend much time on this (i.e. you can just skip these
calls around TLB flushes for now).

Alright; then I'll go directly to benchmarking/regression testing, patch is in final state for me.
