* Chuck Cranor rescinded clauses in his licensejsg2014-07-111-8/+1
| | | | | | | | | | | | | on the 2nd of February 2011 in NetBSD. http://marc.info/?l=netbsd-source-changes&m=129658899212732&w=2 http://marc.info/?l=netbsd-source-changes&m=129659095515558&w=2 http://marc.info/?l=netbsd-source-changes&m=129659157916514&w=2 http://marc.info/?l=netbsd-source-changes&m=129665962324372&w=2 http://marc.info/?l=netbsd-source-changes&m=129666033625342&w=2 http://marc.info/?l=netbsd-source-changes&m=129666052825545&w=2 http://marc.info/?l=netbsd-source-changes&m=129666922906480&w=2 http://marc.info/?l=netbsd-source-changes&m=129667725518082&w=2
* the #ifdef _KERNEL can wrap the entire file. uvm_extern.h only pullsderaadt2014-07-081-10/+2
| | | | this inside #ifdef _KERNEL in any case, so nothing really changes.
* Put the PG_RELEASED changes diff back in.oga2009-07-221-3/+1
| | | | | | | | This has has been tested very very thoroughly on all archs we have excepting 88k and 68k. Please see cvs log for the individual commit messages. ok beck@, thib@
* date based reversion of uvm to the 4th May.oga2009-06-171-1/+1
| | | | | | | | | | | More backouts in line with previous ones, this appears to bring us back to a stable condition. A machine forced to 64mb of ram cycled 10GB through swap with this diff and is still running as I type this. Other tests by ariane@ and thib@ also seem to show that it's alright. ok deraadt@, thib@, ariane@
* Backout all changes to uvm after pmemrange (which will be backed outoga2009-06-161-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | separately). a change at or just before the hackathon has either exposed or added a very very nasty memory corruption bug that is giving us hell right now. So in the interest of kernel stability these diffs are being backed out until such a time as that corruption bug has been found and squashed, then the ones that are proven good may slowly return. a quick hitlist of the main commits this backs out: mine: uvm_objwire the lock change in uvm_swap.c using trees for uvm objects instead of the hash removing the pgo_releasepg callback. art@'s: putting pmap_page_protect(VM_PROT_NONE) in uvm_pagedeactivate() since all callers called that just prior anyway. ok beck@, ariane@. prompted by deraadt@.
* Since we've now cleared up a lot of the PG_RELEASED setting, remove theoga2009-06-011-3/+1
| | | | | | | | pgo_releasepg() hook and just free the page the "normal" way in the one place we'll ever see PG_RELEASED and should care (uvm_page_unbusy, called in aiodoned). ok art@, beck@, thib@
* remove PGO_OVERWRITE, PGO_WEAK and PGO_PASTEOF from the pager. They're alloga2009-03-271-4/+1
| | | | | | unused. ok art@.
* Move all of the pseudo-inline functions in uvm into C files.oga2009-03-251-19/+6
| | | | | | | | | By pseudo-inline, I mean that if a certain macro was defined, they would be inlined. However, no architecture defines that, and none has for a very very long time. Therefore mainly this just makes the code a damned sight easier to read. Some k&r -> ansi declarations while I'm in there. "just commit it" art@. ok weingart@.

* UBC was a disaster. It worked very good when it worked, but on someart2001-12-191-13/+34
| | | | | | | | | machines or some configurations or in some phase of the moon (we actually don't know when or why) files disappeared. Since we've not been able to track down the problem in two weeks intense debugging and we need -current to be stable, back out everything to a state it had before UBC. We apologise for the inconvenience.

| | | | | | | | | | UBC, but prerequsites for it. - Create a daemon that processes async I/O (swap and paging in the future) requests that need processing in process context and that were processed in the pagedaemon before. - Convert some ugly ifdef DIAGNOSTIC code to less intrusive KASSERTs. - misc other cleanups.
