chs f3a668ed84 eliminate the PMAP_NEW option by making it required for all ports.
ports which previously had no support for PMAP_NEW now implement
the pmap_k* interfaces as wrappers around the non-k versions.

thorpej 23e83a7ac7 When handling the MADV_FREE case, if the amap or aobj has more than
one reference, go through the deactivate path; the page may actually
be in use by another process.

Fixes kern/8239.

thorpej 3f176180d5 Garbage collect thread_sleep()/thread_wakeup() left over from the old
Mach VM code.  Also nuke iprintf(), which was no longer used anywhere.

Add proclist locking where appropriate.

thorpej a448b59581 Implement uao_flush(). This is pretty much identical to the "amap flush"
code in uvm_map_clean().

chs f455dd6596 add a `flags' argument to uvm_pagealloc_strat().
define a flag UVM_PGA_USERESERVE to allow non-kernel object
allocations to use pages from the reserve.
use the new flag for allocations in pmap modules.

thorpej 5dd4b45577 Don't use the nointr pool page allocator for the uao_swhash_elt pool. We
need to ensure that these come from a non-pageable kernel map, otherwise
we can run into a deadlock condition (as noticed by Chuck Silvers).
1998-09-18 19:27:20 +00:00
thorpej 5a4981d9b8 Use the pool allocator w/ the "nointr" pool page allocator for uvm_aobj
and uao_swhash_elt structures.  Also, fix a bug in uao_set_swlot() where
if setting the swslot to 0 (freeing swap resources), and no swslot was
currently allocated, a new entry would be allocated anyhow (revealed during
pool'ification).

drochner 9b25897ec0 minor consistency nit: the page index into an anon object is always
assigned to from integer types, and it is compared to integers. So
let it be an integer instead of vsize_t.

mrg f2caacc717 initial import of the new virtual memory system, UVM, into -current.
UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code.  i provided some help
getting swap and paging working, and other bug fixes/ideas.  chuck
silvers <chuq@chuq.com> also provided some other fixes.

this is the UVM kernel code portion.


this will be KNF'd shortly.  :-)
