thorpej 655b21e17d Tell uvm_pagermapin() the direction of the I/O so that it can map
with only the protection that it needs.

chs 03a4ef3a79 remove the "shareprot" pagerop. it's not needed anymore since
share maps are long gone.

kleink a51ef2c3f9 Kill duplicate uvn_attach() prototype (public, already in uvm_vnode.h). 2000-03-27 16:58:23 +00:00
kleink 6e5b64c8a0 Merge parts of chs-ubc2 into the trunk:
Add a new type voff_t (defined as a synonym for off_t) to describe offsets
into uvm objects, and update the appropriate interfaces to use it, the
most visible effect being the ability to mmap() file offsets beyond
the range of a vaddr_t.

Originally by Chuck Silvers; blame me for problems caused by merging this
into non-UBC.

chs b16ae5a8a5 put various debugging printfs under #ifdef DEBUG. 1999-10-19 16:04:45 +00:00
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 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.

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.

sommerfe f1a508e354 Prevent deadlock cited in PR4629 from crashing the system. (copyout
and system call now just return EFAULT).  A complete fix will
presumably have to wait for UBC and/or for vnode locking protocols to
be revamped to allow use of shared locks.

kleink 182e12f413 Remove inclusions of syscall (and syscall argument) related header files;
we don't need them here.

chuck 927ec8b012 bug fix: when doing uvm_vnp_sync() actually skip over blocked uvn's so
that we don't try and sync them later.   should get rid of the
"uvm_vnp_sync: dying vnode on sync list" related warnings that were
occuring during a "make install."

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.  :-)
