pmap.c vm_machdep.c
sys/arch/i386/include: cpu.h i82489var.h pmap.h
Log message:
Just like on amd64. Instead of keeping a bitmap of which cpus a pmap
is active on, save a curpmap pointer in cpu_info. This lets us simplify
a few things and do lazy context switching from a user process to a
kernel thread. There's a new IPI introduced for forcing a cr3 reload
when we're tearing down a dead pmap.
kettenis@ ok (after I polished a few minor things)
