80de1e9903 Upon further investigation, in uvm_map_pageable(), entry->protection is the 
right access_type to pass to uvm_fault_wire().  This way, if the entry has
VM_PROT_WRITE, and the entry is marked COW, the copy will happen immediately
in uvm_fault(), as if the access were performed.

6b655611b1 Wired kernel mappings are wired; pass VM_PROT_READ|VM_PROT_WRITE for

2580d306ab Change the vm_map's "entries_pageable" member to a r/o flags member, which 
has PAGEABLE and INTRSAFE flags.  PAGEABLE now really means "pageable",
not "allocate vm_map_entry's from non-static pool", so update all map
creations to reflect that.  INTRSAFE maps are maps that are used in
interrupt context (e.g. kmem_map, mb_map), and thus use the static
map entry pool (XXX as does kernel_map, for now).  This will eventually
change now these maps are locked, as well.

00a1f75cf6 In uvm_pagermapin(), pass VM_PROT_READ|VM_PROT_WRITE as access_type, to 
ensure we don't take mod/ref emulation faults in an interrupt context
(e.g. during the i/o operation).  This is safe because:
	- For a pageout operation, the page is already known to be
	  modified, and the pagedaemon will pmap_clear_modify() after
	  the pageout has completed.
	- For a pagein operation, pagers must already pmap_clear_modify()
	  after the pagein operation is complete, because the i/o may have
	  been done with e.g. programmed i/o.
XXX It would be nice to know the i/o direction so that we can call
XXX pmap_enter() with only the protection and access_type necessary.

5832084eaf bus_dmamem_map() maps DMA safe memory, which is usually one or more 
managed pages, into KVA space.  Since the pages are managed, we should
use pmap_enter(), not pmap_kenter_pa().

Also, when entering the mappings, enter with an access_type of
VM_PROT_READ | VM_PROT_WRITE.  We do this for a couple of reasons:

	(1) On systems that have H/W mod/ref attributes, the hardware
	    may not be able to track mod/ref done by a bus master.

	(2) On systems that have to do mod/ref emulation, this prevents
	    a mod/ref page fault from potentially happening while in an
	    interrupt context, which can be problematic.

This latter change is fairly important if we ever want to be able to
transfer DMA-safe memory pages to anonymous memory objects; we will need
to know that the pages are modified, or else data could be lost!

Note that while the pages are unowned (i.e. "just DMA-safe memory pages"),
they won't consume any swap resources, as the mappings are wired, and
the pages aren't on the active or inactive queues.

7becac6b9a Don't use pmap_kenter_pgs() for entering pager_map mappings. The pages 
are still owned by the object which is paging, and so the test for a kernel
object in uvm_unmap_remove() will cause pmap_remove() to be used instead
of pmap_kremove().

This was a MAJOR source of pmap_remove() vs pmap_kremove() inconsistency
(which caused the busted kernel pmap statistics, and a cause of much
locking hair on MP systems).

416a47bc88 Define OUIs in a more uniform way. OUIs are fixed entities registered 
with IEEE, so use the "real" OUIs for definitions.
Now unfortunately vendors differ in how the MII ID register bits are
used wrt bit and byte ordering. There is a straightforward way - bits
numbered from LSB to MSB - used by AMD, Intel, NS and QS. This is used
by the current MII_OUI() conversion macro. ICS, Seeq, SiS and TI count
the bits as they appear on the wire, and some differ completely.
Account for these cases by "xx" prefixed OUI definitions which compensate
for this, so the MII_OUI() macro can still be used.
Add AMD (the "real" AMD this time) and the 79c973 PCnet internal PHY.

e5f47f6307 Rewrite the USB keyboard console attachment (again). Grumble, Macintosh 
firmware sets the "stdin" property of /chosen to be a pseudo-hid (yes, they
even spell it incorrectly) that merges all keyboard input into one stream,
so we can't find the USB controller we're attached to.  Instead, just give
it to the first USB keyboard found during autoconfiguration.  So that we
have SOMETHING available early on, use OpenFirmware i/o to do keyboard
input to the console wsdisplay until the USB code attaches the keyboard.
