1999-02-26add some struct members that uvm usesArtur Grabowski
1999-02-19Allocate the u-area early in fork1 instead of in vm_fork.Artur Grabowski
Now we can return ENOMEM instead of doing a panic when we run out of memory.

1998-10-30fix !VM_PAGE_NOADD case which was incompilable.Michael Shalayeff
fix printf() strings so they won't spread all across the screen. kids tested, mother approved.
1998-09-11include pmap.h earlier, so MD pmap structures may beMichael Shalayeff
kept all together in the pmap.h file w/o spreading all over MD includes. verified on most architectures.
1998-07-28Return EINVAL when msg_iovlen or iovcnt <= 0; Make uio_resid unsigned ↵Todd C. Miller
(size_t) and don't return EINVAL if it is < 0 in sys_{read,write}. Remove check for uio_resid < 0 uiomove() now that uio_resid is unsigned and brack remaining panics with #ifdef DIAGNOSTIC. vn_rdwr() must now take a size_t * as its 9th argument so change that and clean up uses of vn_rdwr().

1998-05-11Do not allow mapping of immutable/append-only in a way that allows writing.Niklas Hallqvist
Information about the problem gathered from NetBSD, but solved in a different albeit similar way.

1998-03-30do not count proc0 faults (happens in amiga pmap_init)Niklas Hallqvist
1998-03-26correctly count ru_majflt. the fix pulled in from netbsd pr#1397 ischuck
incorrect. calling vm_pager_get() doesn't count as a "majflt" unless the pager returns VM_PAGER_OK. when walking an object chain we can get VM_PAGER_FAIL (indicating that the requested data does not reside in this object and we must continue to walk the chain) -- we don't want to count this as a majflt. i also added code to count ru_minflt.

needs it.
1998-03-01Merge of MACHINE_NEW_CONTIG (aka MNN) code from Chuck Cranor,Niklas Hallqvist
<chuck@openbsd.org>. This code is as of yet disabled on all platforms, actually not yet supported on more than mvme68k, although other platforms are expected soon, as code is already available. This code makes handling of multiple physical memory regions consistent over all platforms, as well as keeping the performance of maintaining a single continuous memory chunk. It is also a requirement for the upcoming UVM replacement VM system. What I did in this merge: just declared the pmap_map function in a MD include file per port that needs it. It's not an exported pmap interface, says Chuck. It ended up in differnt include files on differnet ports, as I tried to follow the current policy on a per-arch basis.
