4bdbe49cd3 The "active" and "inactive" members of struct uvmexp were removed in 
rev. 1.118 of uvm_extern.h with the merge of yamt-pdpolicy in 2006. So
they shouldn't still be documented as part of the structure. Bump date.

467a0fa1ae Bump date for uarea swap-out removal. 2009-10-21 22:18:37 +00:00
rmind
40cf6f3659 Remove uarea swap-out functionality: 
- Addresses the issue described in PR/38828.
- Some simplification in threading and sleepq subsystems.
- Eliminates pmap_collect() and, as a side note, allows pmap optimisations.
- Eliminates XS_CTL_DATA_ONSTACK in scsipi code.
- Avoids few scans on LWP list and thus potentially long holds of proc_lock.
- Cuts ~1.5k lines of code.  Reduces amd64 kernel size by ~4k.
- Removes __SWAP_BROKEN cases.

Tested on x86, mips, acorn32 (thanks <mpumford>) and partly tested on
acorn26 (thanks to <bjh21>).

Discussed on <tech-kern>, reviewed by <ad>.

8975a0856f adjust the UBC mapping code to support non-vnode uvm_objects. 
this means we can no longer look at the vnode size to determine how many
pages to request in a fault, which is good since for NFS the size can change
out from under us on the server anyway.  there's also a new flag UBC_UNMAP
for ubc_release(), so that the file system code can make the decision about
whether to cache mappings for files being used as executables.
