David Greenman 7609ab12e4 Initialize b_vnbuf.le_next before returning a new buffer in getpbuf and 
trypbuf. Move a couple of splbio's to be slightly less conservative.

David Greenman 6185408336 Don't ever clear B_BUSY on a pbuf (or any other flag for that matter). 
This appears to be the cause of some buffer confusion that leads to
a panic during heavy paging.

Garrett Wollman f23b4c91c4 Fix up some sloppy coding practices: 
- Delete redundant declarations.
- Add -Wredundant-declarations to Makefile.i386 so they don't come back.
- Delete sloppy COMMON-style declarations of uninitialized data in
  header files.
- Add a few prototypes.
- Clean up warnings resulting from the above.

NB: ioconf.c will still generate a redundant-declaration warning, which
is unavoidable unless somebody volunteers to make `config' smarter.

David Greenman 8339815ff9 Made pmap_kenter "TLB safe". ...and then removed all the pmap_updates that 
are no longer needed because of this.

David Greenman 16f62314cd Incorporated post 1.1.5 work from John Dyson. This includes performance 
improvements via the new routines pmap_qenter/pmap_qremove and pmap_kenter/
pmap_kremove. These routine allow fast mapping of pages for those
architectures that have "normal" MMUs. Also included is a fix to the
pageout daemon to properly check a queue end condition.
