        syssrc/sys/arch/i386/i386 [sommerfeld_i386mp_1]: pmap.c

Log Message:
Preliminary TLB shootdown support.
In liu of previous deferred invalidation support, use TLB shootdown
queues even on uniprocessor.

Defer enabling global page support in CR4 until processor class has
been identified.  On a GENERIC kernel which includes 386 support,
turning on global page support before identifycpu has set cpu_class
results in stale global TLB entries which confuse the MP BIOS probe
code.
