David Greenman 0e195446b7 Bug fixes and performance improvements from John Dyson and myself: ... 1) check va before clearing the page clean flag. Not doing so was causing the vnode pager error 5 messages when paging from NFS. (pmap.c) 2) put back interrupt protection in idle_loop. Bruce didn't think it was necessary, John insists that it is (and I agree). (swtch.s) 3) various improvements to the clustering code (vm_machdep.c). It's now enabled/used by default. 4) bad disk blocks are now handled properly when doing clustered IOs. (wd.c, vm_machdep.c) 5) bogus bad block handling fixed in wd.c. 6) algorithm improvements to the pageout/pagescan daemons. It's amazing how well 4MB machines work now.		1994-04-20 07:06:57 +00:00
