Modified Files:
	src/sys/arch/i386/i386 [vmlocking]: cpu.c genassym.cf pmap.c vector.S
	src/sys/arch/i386/include [vmlocking]: cpu.h pmap.h

Log Message:
- Add ci_cpumask and use in preference to (1 << ci_cpuid). Some processors
  are bad at shifting by non-constant amounts.
- pmap_tlb_shootdown() must be called with preemption disabled.
- Defer waiting for tlb shootdown to complete after kenter_pa()/kremove().
  Spin in pmap_update() and in pmap_detactivate(), in case the LWP has been
  preempted
- When preparing to send a multicast shootdown IPI, avoid scanning the list
  of CPUs if the pmap's bitmask indicates that it's only active locally.
