Modified files:
sys/sparc64/include tlb.h tte.h
sys/sparc64/sparc64 exception.s genassym.c pmap.c pv.c tsb.c
Log:
Modify the tte format to not include the tlb context number and to store the
virtual page number in a much more convenient way; all in one piece. This
greatly simplifies the comparison for a matching tte, and allows the fault
handlers to be much simpler due to not having to load wierd masks.
Rewrite the tlb fault handlers to account for the new format. These are also
written to allow faults on the user tsb inside of the fault handlers; the
kernel fault handler must be aware of this and not clobber the other's
registers. The faults do not yet occur due to other support that is needed
(and still under my desk).
