map accurately tracks the same flag in the segments belonging to it.
The map's copy can be set only if all the segments are coherent.
This finally gets NFS writes fully working on my PCI ex(4) card.
- Track unmanaged mappings of RAM more closely by allocating a pvo
for them. This allows us to check more accurately for multiple
cache-mode-incompatible mappings.
- As part of the above, implement pmap_steal_memory(). This has the
beneficial side-effect of moving a fair chunk of kernel data
structures into KSEG0.
now carries the name of the attachment (e.g. "tlp_pci" or "audio"),
and cfattach structures are registered at boot time on a per-driver
basis. The cfdriver and cfattach pointers are cached in the device
structure when attached.
There are several optimizations here:
1) Objects on _rtld_list_main do not participate in the DAG structures
at all. This is okay because all symbols must be resolvable at
link/load time, and _rtld_list_main is always searched first, so
any references from those objects must necessarily be resolved to
other objects on _rtld_list_main.
(Making this work completely required setting obj->main a bit
earlier; hence the RTLD_MAIN hack.)
2) Objects on _rtld_list_main are not put on _rtld_list_global,
preventing an extra search.
3) A bit is used to keep track of whether an object is on
_rtld_list_global, so we don't have to do a silly linear search.
4) A small attempt is made to prevent objects being put on the DAG
lists multiple times (using a silly linear search).
The sum of this appears to be a ~10% (.3s) reduction in Mozilla's
startup time on my 800MHz box.
Also, make sure _rtld_objmain->path is always set, just to make the
debug output nicer.

to do it this way for this type of system (the goal being to encapsulate
as much information about the board as possible into one file).
layers. Common middle layer shared by kbd_zs and sunkbd is moved into
the new file. Move shared config directives to files.sun and adjust
ports' files.* accordingly.
Need this to support console/Xsun on Mr.Coffee JavaStation.
