src/sys/arch/sparc64/sparc64: locore.s machdep.c pmap.c
Log Message:
- in _bus_dmamap_unload(), pmap_page_protect() and pmap_clear_reference()
switch the dcache_flush_page() into a dcache_flush_page_all()
- in both pmap_kremove()/pmap_remove(), remove the blast_dcache() call
and replace it with dcache_flush_page_all()
- in pmap_get_page() [used to allocate PTP's], always call pmap_zero_page(pa)
- flush the dcache of the dst page in pmap_{copy,zero}_page() by redirecting
throught a C function that calls the (renamed) asm. the old asm code had a
comment about needing to do this...
- add a couple of membar #Sync's that the USIII manual recommends
based on discussions with chuq@, skrll@ and mar...@.
these help my SB2000 / SB2500 with both disk / nfs builds and other tasks,
sometimes lasting for several hours before failing or asserting.
