Modified files:
sys/sparc64/include tlb.h
Log:
1. Certain tlb operations need to be atomic, so disable interrupts for
their duration. This is still only effective as long as they are
only used in the static kernel. Code in modules may cause instruction
faults which makes these break in different ways anyway.
2. Add a load bearing membar #Sync.
3. Add an inline for demapping an entire context.
